Q:Does the car change natural gas to the engine?: One of the main problems in the use of natural gas vehicles is that the power of the engine is significantly lower than that of gasoline. According to data reports, the use of natural gas as fuel in the car, power is generally down, natural gas car power decline mainly due to the characteristics of the fuel itself and the structure of the engine.

Q:Is the engine oil burning normal?: Hello Turbocharged engine driving, if not properly, are likely to burn oil, most of the cars have a mass of burning oil, but some owners said no, and this relationship with the T engine, the advantages and disadvantages of turbo engine benefits: maximum power output in the same displacement conditions with T and the maximum torque will be much larger, because the small displacement can output large power consumption, so small can output high power, this is the 2 aspects of the engine, fuel and power have the advantage

Q:Motor engines. Internal combustion engines. What's the difference between engines?: Difference: the motor uses the principle of electromagnetism to transform electric energy into mechanical energy. The internal combustion engine is accomplished by compressing the air to mechanical energy.

Q:What is the role of the engine timing belt?: Timing, that is, through the engine timing mechanism, so that each cylinder just to do: the piston just up to the top dead center, the valve just closed, spark plug just ignition.

Q:What does engine brake mean?: 1, pine door: the general method is mainly used in highway or on the high speed, such as found in front of traffic is large, need to slow down or avoid, this can take this way, (the premise is of course to the taxiway). His advantage is that it can avoid frequent shift, reduce the degree of driver fatigue. To save fuel, improve the economic efficiency of the vehicle.

Q:Is the engine of Chery developed independently?: The most abundant talent reserves: Chery attract global talent, carefully creating a "multinational force", foreign experts from the United States, Japan, Germany, Austria and other automotive research and development power of them, have come back from overseas senior technicians and well-known graduate doctorate or master's degrees, more work in multinational companies for many years overseas returnees talent. This "multinational force" has assumed the main R & D task of Chery company, and has continuously realized the independent innovation of Chery engine technology.

Q:Why is some engine displacement unit CC?: It is the displacement of the motorcycle, because it did not reach 1 liter in milliliter, CC = ML (ml) ml unit, the main unit is liters (L), 1L = 1000mL CC. 1cc = 1 ml cc

Q:What does the MAP diagram of an engine mean?: Then, the ignition requirements are corrected according to the knock sensor signal so that the engine operates at the optimum ignition time.

Q:What brand of the Geely imperial GL engine: The only credible standard for car safety ratings is crash testing. Recent North American IIHS crash test excellent models, Japanese accounted for 7, Germany's bottom line. Did the Germans sell the worst cars to the United States and sell the best cars to China? Ha ha ~ not convinced words, can give me the accident picture, leave the mailbox, here hair map easy to hang

Q:How to maintain the car engine: If the engine is not maintained for a long time will affect the life of the car.
