–
BYD Auto Co. Ltd. is a Chinese automobile manufacturer based in Xian, Shaanxi Province, and a wholly owned subsidiary of BYD Company. It was founded in 2003, following BYD Companys acquisition of Tsinchuan Automobile Company in 2002 and its principal activity is the design, development, manufacture and distribution of passenger cars and buses sold under the BYD brand. It also has a 50,50 joint venture with Daimler AG, Shenzhen BYD Daimler New Technology Co. Ltd. which develops and manufactures luxury electric cars sold under the Denza brand. BYD Auto sold a total of 506,189 passenger cars in China in 2013, making it the tenth-largest selling brand, in 2015, BYD Auto was the best selling global electric vehicle brand, ahead of General Motors and Nissan. For a second running, BYD was the worlds top selling plug-in electric car manufacturer with over 100,000 units delivered in 2016. In October 2016, BYD Auto became the second largest global plug-in car manufacturer after the Renault-Nissan Alliance. In 2008, BYD Auto began selling its first mass-produced, plug-in hybrid vehicle, China subsidizes oil, and Chinese automakers see opportunities in less mature electric vehicles because Western companies have yet to develop much of a lead in the technology. In late December 2008, Warren Buffett spent $230 million on the acquisition of a 10% stake in BYD Autos parent, in 2009, the company sold 448,400 cars in China, and two-thirds of sales were its BYD F3 model. In the same year, BYD began the export of its cars to Africa, South America, some of its first all-electric vehicles were offered via fleet sales to government buyers in China. The BYD Qin plug-in hybrid, launched in the Chinese market in December 2013, the car also ranked seventh among the worlds top 10 best selling plug-in cars in 2014. In 2015, the Qin remained as the top selling new energy vehicle in China. The BYD Qin was the second best selling plug-in hybrid car in 2015. Three BYD Auto models topped the Chinese ranking of best-selling new energy cars in 2016. The BYD Tang plug-in hybrid SUV was the top selling car with 31,405 units delivered, followed by the BYD Qin. As of December 2016, the BYD Qin, with 68,655 units sold since its inception, as of 2015, BYD was in the process of opening its first passenger car factory in Brazil to focus on supplying electric vehicles for taxis and car-sharing schemes. BYD ended 2015 as the top selling manufacturer of highway legal light-duty plug-in electric vehicles, with 61,772 passenger vehicles sold. BYD Auto was followed by Tesla Motors with 50,580 units sold in 2015, accounting for heavy-duty vehicles, BYD total sales rises to 69,222 units. BYD continued as the top selling plug-in car manufacturer in 2016 with over 100,000 units sold, up 64% from 2015

Car classification
–
Governments and private organizations have developed car classification schemes that are used for innumerable purposes including regulation, description and categorization, among others. This article details commonly used classification schemes in use worldwide, vehicles can be categorized in numerous ways. Regulatory agencies may also establish a vehicle classification system for determining a tax amount, in the United Kingdom, a vehicle is taxed according to the vehicles construction, engine, weight, type of fuel and emissions, as well as the purpose for which it is used. Other jurisdictions may determine vehicle tax based upon environmental principles, such as the user pays principle, another standard for road vehicles of all types that is used internationally, is ISO 3833-1977. In the United States, since 2010 the Insurance Institute for Highway Safety uses a scheme it has developed that takes into account a combination of both shadow and weight. The United States Federal Highway Administration has developed a scheme used for automatically calculating road use tolls. There are two categories depending on whether the vehicle carries passengers or commodities. Vehicles that carry commodities are further subdivided by number of axles and number of units, the United States Environmental Protection Agency has developed a classification scheme used to compare fuel economy among similar vehicles. Passenger vehicles are classified based on a total interior passenger. Trucks are classified based upon their gross vehicle weight rating, heavy duty vehicles are not included within the EPA scheme. A similar set of classes is used by the Canadian EPA, in Australia, the Federal Chamber of Automotive Industries publishes its own classifications. This is a table listing several different methods of vehicle classification. Straddling the boundary between car and motorbike, these vehicles have engines under 1.0 litre, typically only two passengers, and are sometimes unorthodox in construction. Some microcars are three-wheelers, while the majority have four wheels, microcars were popular in post-war Europe, where their appearance led them to be called Bubble cars. More recent microcars are often electric powered, the size of ultracompact cars will be less than minicars, but have engine greater than 50cc displacement and able to transport 1 or 2 persons. Ultracompact cars cannot use standard, because of strict safety standards for minicars. The regulation about running capacity and safety performance of cars will be published in early autumn. Today, there are smaller than ultracompact cars, called category-1 motorized vehicles which it has 50cc displacement or less

Compact car
–
The dimension standards are absolute, meaning special consideration is not made for SUVs, CUVs, minivans, station wagons or hatchbacks. Compact car is a largely North American term denoting an automobile smaller than a mid-size car, Compact cars usually have wheelbases between 100 inches and 109 inches. The United States Environmental Protection Agency defines a car as measuring between 100 cubic feet and 109 cubic feet of combined passenger and cargo volume capacity. Vehicle class size is defined in the U. S. by environmental laws in the Code of Federal Regulations, Title 40—Protection of Environment, Section 600. 315-82 Classes of comparable automobiles. Passenger car classes are defined based on interior volume index or seating capacity, in the United States, the compact car segment currently holds a 16% share of the market. This segment is dominated by import models, one of the first truly small cars on the U. S. market, in the sense that it was considerably smaller than the standard- size cars of its day, was the Austin Bantam that appeared in 1930. Production of the British-based city car lasted only four years with a total of 20,000 units, although other little cars such as the Crosley focused on low price and economy, Americans did not take easily to small cars. The U. S. market after World-War II experienced growth in sales in standard-sized cars, by 1947, Chevrolet had prototypes of the Cadet, an economy car developed by Earle S. MacPherson. Ford also experimented with a car and, unlike Chevrolets Cadet, production ensued for the European market as a large car. In 1950, Nash introduced a convertible Rambler model and it was built on a 100-inch wheelbase to which a station wagon, hardtop, and sedan versions were added. Compared to European standards, they were large, conceived by George W. Mason, the term compact was coined by George W. Romney as a euphemism for small cars with a wheelbase of 110 inches or less. The Nash Rambler established a new segment, it became known as Americas first small car. Several competitors to the Nash Rambler arose from the ranks of Americas other independent automakers, other early compact cars included the Henry J from Kaiser-Frazer, as well as the Willys Aero and the Hudson Jet. In 1952, Ford Division assistant general manager Robert S. McNamara started the Market Research Unit, in 1954,64,500 of over 5 million cars sold in the United States were imports or small American cars. Ford alone sold over 1.4 million big cars, yet 5 percent of those surveyed said they would consider a small car. These models also gave rise to compact vans that were sized similarly to the Volkswagen Type 2 microbus and were based from the Falcon, Corvair, and Valiant automobile platforms. Ford Division marketing research manager George Brown said smaller cars appealed to people with a college education, the cars had to offer not only high gas mileage but also headroom, legroom, and plenty of trunk space. Within a few years after that, the compacts had given rise to a new class called the car, named after the Ford Mustang

BYD F3DM
–
The BYD F3DM was a plug-in hybrid compact sedan manufactured by BYD Auto with an all-electric range of 37 miles and a hybrid electric powertrain that can extend the range an additional 300 miles. The F3DM is the worlds first mass-produced plug-in hybrid automobile and went on sale to government agencies, during its first year in the market the F3DM plug-in sold only 48 vehicles. Sales to the public began in Shenzhen in March 2010. Cumulative sales in China reached 3,284 units through October 2013, when sales ended, a testing program was launched in the U. S. on December 2010 with the participation of the Housing Authority of the City of Los Angeles. The F3DM was expected to go on sale in the U. S. in 2012 at a price of US$28,800 before any government incentives, in October 2011 BYD announced that retail sales will be delayed due to the lack of charging infrastructure. In April 2012 BYD announced that due to its low sales, the F3DM was to be replaced by the BYD Qin plug-in hybrid, Qin deliveries in China began in mid December 2013. As of May 2013, the F3DM was no longer in production, the F3DM was introduced at the 2008 Geneva Motor Show, preceded by the F6DM concept car which was first unveiled in the North American International Auto Show in January 2008. BYD Auto uses a 16 kWh lithium iron phosphate batteries for the F3DM, BYD has said their LiFePO4 batteries are inherently safe because they are more chemically stable, although they pack less energy in each cell, compared with more conventional lithium-ion batteries. The F3DM battery pack consist of 1003. 3-volt cells stored under the cabin, BYD says the car will have a 60 miles all-electric range as well as a gasoline engine that allows operation in hybrid mode that extend the range for an additional 300 miles. The electric range assumes the car is traveling at a constant speed of 50 km/h, the F3DM has a roof-mounted large solar panel capable of providing electric energy to run vehicle accessories such as the radio and climate control. At that point, the F3DM’s 1-liter 3-cylinder engine kicks in to bring the battery charge as close as possible to 30%, the F3DM has a direct connection between the gasoline engine and the wheels that is useful when accelerating onto a highway, just like the Prius. Under high-load circumstances, the 68 horsepower gasoline engine combines with the motors to deliver a total of 168 horsepower. BYD calls the F3DM is a vehicle because it allows the driver to manually switch from all-electric to plug-in hybrid operation. The hybrid powertrain uses a 1. 0-liter engine with battery-assisted acceleration at low speeds, the estimated fuel economy is 30 mpg‑US. On December 15,2008, the F3DM began selling for 149,800 yuan, in April 2009, the CEO Wang Chuanfu announced the price will be lowered to increase sales, but currently the price of a 2010 F3DM is up to 169,800 yuan. Wang also wants an independent verification of the cars on-road performance, during its first year in the market the F3DM plug-in sold only 48 vehicles to corporate and government customers. During 2009 BYD Auto sold 290,963 of the gasoline-powered F3s, among the reasons cited for the slow sales are the lack of infrastructure to charge, the high battery cost, and also the batteries have been reported to be unreliable. As the F3DM nearly doubles the price of cars that run on conventional fuel, similar subsidies are expected in other cities

Inline-four engine
–
The inline-four engine or straight-four engine is a type of inline internal combustion four-cylinder engine with all four cylinders mounted in a straight line, or plane along the crankcase. The single bank of cylinders may be oriented in either a vertical or a plane with all the pistons driving a common crankshaft. Where it is inclined, it is called a slant-four. In a specification chart or when an abbreviation is used, an engine is listed either as I4 or L4. The inline-four layout is in primary balance and confers a degree of mechanical simplicity which makes it popular for economy cars. However, despite its simplicity, it suffers from an imbalance which causes minor vibrations in smaller engines. These vibrations become more powerful as engine size and power increase, the inline-four is the most common engine configuration in modern cars, while the V6 engine is the second most popular. This inline engine configuration is the most common in cars with a displacement up to 3.0 L, in practice, the displacement of inline-four petrol engines in cars rarely exceeds this figure. For example, the largest engine of this form on the U. S. market in model year 2015 is the Toyota 2TR-FE, however, there are some notable exceptions. Early vehicles also tended to have engines with larger displacements to develop horsepower, the Model A Ford was built with a 3.3 L inline-four engine. Inline-four diesel engines, which are lower revving than gasoline engines, Mitsubishi still employs a 3.0 L inline-four diesel. Generally, European and Asian manufacturers of trucks with a vehicle weight rating between 7.5 and 18 tonnes use inline four-cylinder diesel engines with displacements around 5 L. The MAN D0834 engine is a 4.6 L inline-4 with 220 hp and 627 lb·ft, the Isuzu Forward is a medium-duty truck which is available with a 5.2 L inline-four engine that delivers 210 hp and 470 lb·ft. The Hino Ranger is a medium-duty truck which is available with a 5.1 L inline-four engine that delivers 175 hp and 465 lb·ft, the earlier Hino Ranger even had a 5.3 L inline-four engine. The Kubota M135X is a tractor with a 6.1 L inline-four and this turbo-diesel engine has a bore of 118 mm and a relatively long stroke of 140 mm. One of the strongest Powerboat-4-cylinders is the Volvo Penta D4-300 turbodiesel and this is a 3.7 L-inline-4 with 300 hp and 516 lb·ft. Brunswick Marine built a 127 kW3.7 L 4-cylinder gasoline engine for their Mercruiser Inboard/outboard line, the block was formed from one half of a Ford 460 cubic inch V8 engine. This engine was produced in the 1970s and 1980s, One of the largest inline-four engines is the MAN B&W 4K90 marine engine

Turbocharger
–
Turbochargers were originally known as turbosuperchargers when all forced induction devices were classified as superchargers. Nowadays the term supercharger is usually applied only to mechanically driven forced induction devices, compared to a mechanically driven supercharger, turbochargers tend to be more efficient, but less responsive. Twincharger refers to an engine with both a supercharger and a turbocharger, turbochargers are commonly used on truck, car, train, aircraft, and construction equipment engines. They are most often used with Otto cycle and Diesel cycle internal combustion engines and they have also been found useful in automotive fuel cells. Forced induction dates from the late 19th century, when Gottlieb Daimler patented the technique of using a pump to force air into an internal combustion engine in 1885. During World War I French engineer Auguste Rateau fitted turbochargers to Renault engines powering various French fighters with some success, in 1918, General Electric engineer Sanford Alexander Moss attached a turbocharger to a V12 Liberty aircraft engine. Turbochargers were first used in aircraft engines such as the Napier Lioness in the 1920s. Ships and locomotives equipped with turbocharged diesel engines began appearing in the 1920s, turbochargers were also used in aviation, most widely used by the United States. During World War II, notable examples of U. S. aircraft with turbochargers include the B-17 Flying Fortress, B-24 Liberator, P-38 Lightning, and P-47 Thunderbolt. Turbochargers are widely used in car and commercial vehicles because they allow smaller-capacity engines to have improved fuel economy, reduced emissions, higher power, in contrast to turbochargers, superchargers are mechanically driven by the engine. Belts, chains, shafts, and gears are common methods of powering a supercharger, for example, on the single-stage single-speed supercharged Rolls-Royce Merlin engine, the supercharger uses about 150 horsepower. Yet the benefits outweigh the costs, for the 150 hp to drive the supercharger the engine generates an additional 400-horsepower, a net gain of 250 hp. This is where the principal disadvantage of a supercharger becomes apparent, another disadvantage of some superchargers is lower adiabatic efficiency as compared to turbochargers. Adiabatic efficiency is a measure of an ability to compress air without adding excess heat to that air. Even under ideal conditions, the compression process always results in elevated temperature, however. Roots superchargers impart significantly more heat to the air than turbochargers, thus, for a given volume and pressure of air, the turbocharged air is cooler, and as a result denser, containing more oxygen molecules, and therefore more potential power than the supercharged air. In practical application the disparity between the two can be dramatic, with turbochargers often producing 15% to 30% more power based solely on the differences in adiabatic efficiency. By comparison, a turbocharger does not place a direct mechanical load on the engine, although turbochargers place exhaust back pressure on engines, in contrast to supercharging, the primary disadvantage of turbocharging is what is referred to as lag or spool time

Manual transmission
–
A manual transmission, also known as a manual gearbox, stick shift, n-speed manual, standard, MT, or in colloquial U. S. English, a stick, is a type of transmission used in motor vehicle applications. The number of gear ratios is often expressed for automatic transmissions as well. Manual transmissions often feature a clutch and a movable gear stick. This type of transmission is called a sequential manual transmission. In a manual transmission, the flywheel is attached to the engines crankshaft, the clutch disk is in between the pressure plate and the flywheel, and is held against the flywheel under pressure from the pressure plate. When the engine is running and the clutch is engaged, the flywheel spins the clutch plate, as the clutch pedal is depressed, the throw out bearing is activated, which causes the pressure plate to stop applying pressure to the clutch disk. This makes the clutch plate stop receiving power from the engine, when the clutch pedal is released, the throw out bearing is deactivated, and the clutch disk is again held against the flywheel, allowing it to start receiving power from the engine. Manual transmissions are characterized by gear ratios that are selectable by locking selected gear pairs to the shaft inside the transmission. Conversely, most automatic transmissions feature epicyclic gearing controlled by brake bands and/or clutch packs to select gear ratio, automatic transmissions that allow the driver to manually select the current gear are called manumatics. A manual-style transmission operated by computer is called an automated transmission rather than an automatic. Operating aforementioned transmissions often use the pattern of shifter movement with a single or multiple switches to engage the next sequence of gear selection. The earliest form of a transmission is thought to have been invented by Louis-René Panhard. This type of transmission offered multiple gear ratios and, in most cases and these transmissions are called sliding mesh transmissions or sometimes crash boxes, because of the difficulty in changing gears and the loud grinding sound that often accompanied. Newer manual transmissions on cars have all gears mesh at all times and are referred to as constant-mesh transmissions, in both types, a particular gear combination can only be engaged when the two parts to engage are at the same speed. To shift to a gear, the transmission is put in neutral. The vehicle also slows while in neutral and that slows other transmission parts, so the time in neutral depends on the grade, wind, for both upshifts and downshifts, the clutch is released while in neutral. Some drivers use the only for starting from a stop. Even though automobile and light truck transmissions are now almost universally synchronized, transmissions for trucks and machinery, motorcycles

Automatic transmission
–
The number of forward gear ratios is often expressed for manual transmissions as well. The most popular form found in automobiles is the automatic transmission. Similar but larger devices are used for heavy-duty commercial and industrial vehicles. This system uses a coupling in place of a friction clutch. These systems have a set of gear ranges, often with a parking pawl that locks the output shaft of the transmission to keep the vehicle from rolling either forward or backward. Some machines with limited speed ranges or fixed engine speeds, such as forklifts and lawn mowers. Despite superficial similarity to other transmissions, traditional automatic transmissions differ significantly in internal operation and drivers feel from semi-automatics and CVTs. In contrast to conventional automatic transmissions, a CVT uses a belt or other torque transmission scheme to allow a number of gear ratios instead of a fixed number of gear ratios. A semi-automatic retains a clutch like a transmission, but controls the clutch through electrohydraulic means. The ability to shift gears manually, often via paddle shifters, can also be found on certain automated transmissions, semi-automatics, the obvious advantage of an automatic transmission to the driver is the lack of a clutch pedal and manual shift pattern in normal driving. This allows the driver to operate the car with as few as two limbs, allowing amputees and other disabled individuals to drive, the automatic transmission was invented in 1921 by Alfred Horner Munro of Regina, Saskatchewan, Canada, and patented under Canadian patent CA235757 in 1923. Being a steam engineer, Munro designed his device to use compressed air rather than hydraulic fluid and they were incorporated into GM-built tanks during World War II and, after the war, GM marketed them as being battle-tested. However, a Wall Street Journal article credits ZF Friedrichshafen with the invention, zFs origins were in manufacturing gears for airship engines beginning in 1915, the company was founded by Ferdinand von Zeppelin. Modern automatic transmissions can trace their origins to an early horseless carriage gearbox that was developed in 1904 by the Sturtevant brothers of Boston and this unit had two forward speeds, the ratio change being brought about by flyweights that were driven by the engine. At higher engine speeds, high gear was engaged, as the vehicle slowed down and engine RPM decreased, the gearbox would shift back to low. Unfortunately, the metallurgy of the time wasnt up to the task, and owing to the abruptness of the gear change, the next significant phase in the automatic transmissions development occurred in 1908 with the introduction of Henry Fords remarkable Model T. The pedals actuated the transmissions friction elements to select the desired gear, in 1934, both REO and General Motors developed semi-automatic transmissions that were less difficult to operate than a fully manual unit. These designs, however, continued to use a clutch to engage the engine with the transmission, parallel to the development in the 1930s of an automatically shifting gearbox was Chryslers work on adapting the fluid coupling to automotive use

Renminbi
–
The renminbi /ˌrɛnmɪnˈbiː/ is the official currency of the Peoples Republic of China. The yuan is the unit of the renminbi, but is also used to refer to the Chinese currency in general. The distinction between the terms renminbi and yuan is similar to that between sterling and pound, which refer to the British currency and its primary unit. One yuan is subdivided into 10 jiao, and a jiao in turn is subdivided into 10 fen, the ISO code for renminbi is CNY, or also CNH when traded in off-shore markets such as Hong Kong. The currency is often abbreviated RMB, or indicated by the yuan sign ¥, in Chinese texts the currency may also be indicated with the Chinese character for the yuan, 圆. The renminbi is legal tender in mainland China, but not in Hong Kong or Macau, renminbi is sometimes accepted in Hong Kong and Macau, and are easily exchanged in the two territories, with banks in Hong Kong allowing people to maintain accounts in RMB. The currency is issued by the Peoples Bank of China, the authority of China. Until 2005, the value of the renminbi was pegged to the US dollar and it has previously been claimed that the renminbis official exchange rate was undervalued by as much as 37. 5% against its purchasing power parity. Since 2006, the exchange rate has been allowed to float in a narrow margin around a fixed base rate determined with reference to a basket of world currencies. The Chinese government has announced that it gradually increase the flexibility of the exchange rate. As a result of the rapid internationalization of the renminbi, it became the worlds 8th most traded currency in 2013, and 5th in 2015. On 1 October 2016, the RMB became the first emerging market currency to be included in the IMFs special drawing rights basket, a variety of currencies circulated in China during the Republic of China era, most of which were denominated in the unit yuán. Each was distinguished by a name, such as the fabi, the gold yuan. During the era of the economy, the value of the renminbi was set to unrealistic values in exchange with western currency. The unrealistic levels at which exchange rates were pegged led to a black market in currency transactions. In the late 1980s and early 1990s, China worked to make the RMB more convertible, through the use of swap centres, the exchange rate was brought to realistic levels and the dual track currency system was abolished. As of 2013, the renminbi is convertible on current accounts, the ultimate goal has been to make the RMB fully convertible. From 1949 until the late 1970s, the state fixed Chinas exchange rate at a highly overvalued level as part of the countrys import -substitution strategy

The history of the started in a backyard in Stuttgart-West as the Werkstätte für Feinmechanik und Elektrotechnik on November 15,1886. One year later, Bosch presented the first low voltage magneto for gas engines, twenty years later, the first magneto for automobiles followed. The first factory was opened by Bosch in Stuttgart in 1901, in 1906, the company produced its 100, 000-th magneto. In the same year, Bosch introduced the 8-hours day for workers, in 1910, the Feuerbach plant was founded and built close to Stuttgart. In this factory, Bosch started to produce headlights in 1913, in 1917, Bosch was transformed into a corporation. In 1926, Bosch started to produce windscreen wipers, and in 1927, Bosch bought the gas appliances production from Junkers & Co. in 1932. In the same year, the company developed its first power drill, in 1937, Bosch was transformed into a limited liability company. Boschs subsidiary, Dreilinden Maschinenbau GmbH was a manufacturer in Kleinmachnow. This subsidiary employed forced laborers, prisoners of war and concentration camp detainees, there are two books published by Angela Martin and Hanna Sjöberg that report about Boschs use of slave labor. Since 2006, there is a commemoration in the forced labor camp. On March 12,1942, the founder, Robert Bosch. After the second war, Bosch established a partnership with the Japanese company Denso. In 1964, the Robert Bosch Stiftung was founded, Bosch founded a new development center in Schwieberdingen in 1968, and headquarters moved to Gerlingen in 1970. In 1981, the company participated on an equity basis in the Telefonbau & Normalzeit GmbH that was renamed Telenorma in 1985, in 1994, this part of the company was renamed as Bosch Telecom GmbH. In 2000, Bosch sold the Private Networks area, in 2001, Bosch acquired the Mannesmann Rexroth AG which was later renamed to Bosch Rexroth AG
