Q: BMW x3 sudden driving in the engine failure lights with what is the reason?: Under normal circumstances, the knock is divided into sensory detonation and no sense of knocking, in the absence of detonation circumstances, the engine computer will be adjusted according to the situation to adjust the engine control parameters, to avoid greater adverse effects, but

Q: What is the difference between the advantages and disadvantages of the turbine turbo vortex turbofan engine?: The vacuum of the cylinder in the intake process of the engine is not easy to completely inhale such a large volume of air.Therefore, it is very important to improve the ability of the engine to inhale the gas, that is, to improve the filling efficiency of the engine. There are two ways to increase the engine

Q: How many kinds of lubrication are there in an automobile engine?: (2) splash lubrication: a way to lubricate the friction surface by splashing oil droplets and oil mist from some moving parts (mainly crankshaft and camshaft) when the engine is working. Suitable for exposed parts of the surface splash lubrication, such as cylinder, cam; relative speed of the lower parts, such as piston pin; mechanical load lighter parts, such as tappet etc.. The wall of the cylinder is lubricated by splash, and it also prevents the engine working condition from deteriorating because of the high pressure of lubricating oil and excessive oil.

Q: The two major engines and six systems: So people have added a turbocharged system, but in the strict sense of the engine of the two major institutions, the five major systems, there is no turbo system.

Q: How does the engine fail to check?: 3, gasoline octane number is too low lead to no ignition when the mixture naturally appear more serious knock

Q: Ask a question. If the engine is missing the cylinder, will it turn on the trouble light?: Will light machine fault light (yellow light) or lack of cylinder, the most obvious is the idle speed instability.. engine sounds abnormal

Q: Why some engine exhaust pipe in front, some are in the back! What are the advantages and disadvantages: Which for many riders may be a relatively vague words, but in fact it has been very wide in our side, and open the hood to see, maybe your car is using the anti-engine!

Q: What are the performance differences between the four engines of the L, V, W, and H?: The rotary engine is called the triangle piston rotor engine. It is a kind of special piston engine. The rotor piston is a convex arc triangle, when the rotor in the epitrochoid ellipse cylinder rotates, the arc edge of three vertices of triangle and the cylinder wall to maintain contact, thus forming three mutually separated rotor arc the wall between the studio. Turn the volume of the three studio with the rotor and the periodic change, the rotor rotates a circle, each studio can finish a four stroke, the four strokes of the four stroke engine with piston reciprocating corresponding, to form a complete cycle of work.

Q: What is the 4GB2 engine?: The new and 1.5L VVT (4GB2 power) is JAC joint international renowned research institutions, the integration of the world advanced power technology research and development resources, a new generation of aluminum 1.5L VVT small displacement engine together with the international first-class R & D manufacturing, international leading technology. Based on the international leading technology of MITSUBISHI 4A91 platform optimization design, for the upgrading of MITSUBISHI 4G15 technology version of the perfect presentation. The perfect presentation of the six major performance improvements:

Q: What is the difference between a piston engine and a jet engine?: Piston engine as the name suggests is fuel combustion to promote the piston movement, and then converted into crankshaft rotation, similar to the ordinary internal combustion engine.
