Q:What is the 4GB2 engine?: 1, DOHC and VVT DOHC VVT Technology: the technology in the MITSUBISHI 4A91 optimization, better than Honda's VTEC and TOYOTA's VVTI technology, low fuel consumption, low emission and high performance. 2, aluminum magnesium alloy pressure casting cylinder: domestic MITSUBISHI 4G series of economical small displacement engines are cast iron cylinder block. Jianghuai 4GB2 uses aluminum magnesium cylinder to make the engine weight less than 1.3 of the displacement 4G engine, and the engine is lightweight, which can improve the heat dissipation capability, speed up performance and fuel economy of the 80%

Q:What is the difference between the car's brake and the engine brake?: The engine brake is by the engine itself (by changing the low side and so on with the engine brake car in a form)

Q:Cloud 490 engine how: Diesel engine production means for the late 90s into the technological transformation facilities, in the same industry leading level.

Q:W12 engine and V12 engine which strong? The: V-type arrangement: the cylinder was two columns, installed in a crankshaft, two cylinders for the V-shaped arrangement, hence the name, a little bit for the small size, but the higher cost.

Q:Is China really a country that doesn't build an engine?: It is a false proposition that China can not build an engine. The real argument is that China can not build a high engine that is in line with the world's advanced level. Because of the lack of basic materials and processes as well as previous laymen and other reasons, with the international advanced level of nature is not a small gap, consistent with the level of Chinese current engine series and the western world about the level in 90s, but is now gradually catch up with.

Q:What is the problem of engine torque failure?: According to your feedback, it may be caused by clutch slipping. It is suggested that you contact the local 4S shop for inspection and maintenance. Torque sensor can consult Lan Ling technology procurement.

Q:Motor engines. Internal combustion engines. What's the difference between engines?: Motor: that is motor, engine. The working principle is that the starter rotor is driven by electromagnetic induction, and the small gear on the rotor drives the engine flywheel to rotate. An engine is a machine capable of converting other forms of energy into mechanical energy, including, for example, internal combustion engines (gasoline engines, etc.), external combustion engines (Stryn engines, steam engines, etc.), motors, etc..

Q:Why China does not have advanced aero engines, ship engines, and even the world's leading car engines are not?: Second, the modern aero engine and ship engine principle of the same, but the implementation of technology on the aviation engine more sophisticated, so the production of advanced ship engine country distribution is much broader, such as the United States.

Q:What are the criteria for judging the performance of an automobile engine?: 3. front engine and front wheel drive (FF): it is the layout that is gradually becoming popular in domestic and international cars in 1990s. In order to shorten the length of the vehicle, reduce car quality, often before the engine is arranged on the front axle, transmission after things move forward, transmission and drive axle as a whole, fixed on the engine side, the power is delivered directly to the front wheel, reduce chassis height, improve handling and stability at high speed. Such as the common Audi 100 sedan, and mini car (Xiali, Alto) with front engine, front wheel drive transmission system arrangement, common front engine, front axle drive car also has two kinds of structure: one is the motor axis and front axle parallel to the horizontal type (such as Xiali car); two is the engine a vertical (such as Santana, Audi and other car).

Q:Suzuki k10b g13b how about the engine?: The engine is almost no opponent in the small displacement.
