As of 1985
2904-668: The most common fuels are residue oils . Günter Mau argues that no uniform standards for such fuels exist, which is why they have several different colloquial names, including Marine Intermediate Fuel , Heavy Fuel Oil , Marine Bunker Fuel , and Bunker C Fuel . Heavy fuel oils were also used in the Jumo 205 two-stroke diesel aircraft engine. In the 1960s, residue oils were "concocted on the basis of refinery waste". Residue oils are of very low quality with high viscosity and low cetane numbers , but cheap and thus economical to use. Dongfeng Motor Corporation Dongfeng Motor Corporation Ltd.

Former truck models: UD Trucks ceased its Japanese bus production in 2011, but in 2014 launched
3168-572: The percentage of consumer offerings was likely lower as passenger car counts may include microvans , tiny commercial vehicles that are popular in China. Between 1978 and 1985 alongside the market-based Chinese economic reforms instituted by Deng Xiaoping , Dongfeng was transformed from a manufacturer of two heavy-duty trucks with fragmented operations and ownership into a single, centrally managed enterprise. This process included placing all Dongfeng operations—from part manufacture to vehicle assembly—under
3234-404: The petrol or gasoline used in spark-ignition engines, making them less volatile with a higher flash point and giving them higher energy density . They are therefore easier and safer to handle and occupy less volume for a given amount of energy. Two stroke diesels usually burn even heavier grades of fuel oil than standard diesel fuels . In two-stroke marine diesel engines for sea-going craft,

Specific to EMD two-stroke engines ( 567 , 645 , and 710 ): Specific to GM two-stroke ( 6-71 ) and related on-road/off-road/marine two-stroke engines: Fuels used in diesel engines can be composed of heavier hydrocarbon oils than
3366-551: The remaining ones are fixed by the mechanical design of the engines. The scavenging ports are open from 45 degrees before BDC, to 45 degrees after BDC. However, some manufacturers make the scavenging port timing asymmetric by offsetting the crankshaft. The remaining, adjustable, parameters have to do with exhaust valve and injection timing (these two parameters are not necessarily symmetrical about TDC or, for that matter, BDC), they are established to maximize combustion gas exhaust and to maximize charge air intake. A single camshaft operates

As the Chinese economy improved, and as a result of the Sino-Soviet split , production of military trucks came into the spotlight again, and construction of the Second Automobile Works ( 第二汽车制造厂 ) was included in the third five-year plan in 1965. The company was officially founded in 1969 at a village of 100 residents, that would later grow to become Shiyan city. This remote location
3564-469: The stages overlap through most of the engine's operation. This makes its thermodynamic and aerodynamic processes more complex. Because the four-stroke cylinder fires only every other revolution, the power output of the two-stroke cycle is theoretically twice as much. However, the scavenging losses make this advantage difficult to achieve in practice. In most EMD and GM (i.e. Detroit Diesel ) two-stroke engines, very few parameters are adjustable and all

But in 1995, the company was experiencing financial difficulties as was the case with many Chinese automobile manufacturers at this time. The situation was still dire in 1998 precipitating a 1999 restructuring of the company. In 1992, the company changed its name to Dongfeng, or "East Wind" in Chinese. This state owned enterprise has come into conflict with authority at both

In collaboration with Blohm + Voss in Hamburg , MAN Nürnberg built the first double-acting piston two-stroke engine for marine use in 1913/1914. Paul Henry Schweitzer argues that
3894-464: Was also the first civilian truck by the company. At its peak the EQ140 held a domestic market share of 66%. In 1986, Dongfeng surpassed 100,000 vehicles produced annually. In 1987, a new 3-ton model was launched. Traditionally manufacturing commercial vehicles, by 2001 these made up about 73% of Dongfeng's production. By 2012, that figure had reversed, and 73% of manufactures were passenger cars. However,
3960-522: Was chosen as its topography consisted of over 40 shallow valleys, allowing factories to be concealed, while also being on the route of the Xiangyang–Chongqing railway . Due to its remote countryside location with limited equipment, the company only managed to produce 200 automobiles by 1972. In 1975, the first EQ240 2.5-ton Dongfeng truck was produced, followed by the EQ140 5-ton model in 1978, which
