Q:Motorcycle Engine Type Four Stroke What does it mean
Two-stroke engine to burn gasoline and oil mixed oil, while the four-stroke engine only burn pure gasoline.
Q:What kind of engine is oil efficient?
Many owners choose, often mainly look at the manufacturers to provide the same speed fuel consumption data, determine whether fuel-efficient, in fact, there are many parameters affecting fuel consumption. The weight factors -- influence on a car fuel consumption is actually the biggest weight. At the same distance, the more heavy the car does, the more fuel it needs. People often say that the Japanese car engine fuel, in addition to outside factors, the Japanese car weighs more often than cars in Europe and America light is also a very important reason.
Q:What is the driving brake? Parking brake; the meaning of engine brake; what does emergency braking mean?

Q:How about the tu3af engine?
By updating the engine control software, the use of electronic solar term door, increase control thermostat, new outfit three waycatalytic measures (the engine body changes and ultimately, PSA little) TU3JP to meet the European IV emission standard, and the maximum torque increase
Q:What is the meaning of the car's engine VVT, CVT?
, Reduce the fuel consumption.VVT technology is the development trend of car power.
Q:Passat, Teana, Reiz which car V6 engine is the best

Q:What does engine brake deceleration mean?
The so-called "engine braking" is the driving behavior of a term, it is generated by the engine running resistance to effectively control the speed, you have said "downshifting" and "loose throttle" two measures can be achieved using the engine to control the speed of resistance.
Q:EFI engine Neutral sliding is fuel-efficient?
First, EFI engine neutral skid not only will not fuel-efficient, but also to a certain extent more costly oil.
