What are the two major engines of the engine, the four major systems?
(3) the fuel supply system of gasoline engine fuel supply system function is based on the requirements of the engine, with certain number and concentration of mixed gas, and into the cylinder and combustion of the exhaust discharged from the cylinder into the atmosphere; diesel engine fuel supply system function is the diesel fuel and air are supplied into the cylinder the combustion in the combustion chamber, and the formation of mixed gas, the combustion of the waste discharge.
(2) valve valve function is based on the work order and the work process of the engine, the timing of opening and closing the intake valve and exhaust valve, the combustible mixed gas or air into the cylinder, and the exhaust gas from the cylinder exhaust ventilationimplementation process. The gas distribution mechanism of most of the overhead valve type gas distribution mechanism in general, the valve group, valve group and valve driving group.
(1) crank crank the engine realizes the operating cycle, complete the energy conversion the main motion parts. It consists of the body, the piston linkage and the crank flywheel group. During the power stroke of the piston the gas pressure in a cylinder linear motion and rotary motion into the crankshaft through the connecting rod, and the crankshaft outputpower. In the intake, compression and exhaust stroke, flywheel energy release and the rotary movement of the crankshaft into linear movement of the piston.
You're a diesel, right? The diesel engine consists of two big mechanisms and four big systems, that is, crank connecting rod mechanism, valve train, fuel supply system, lubrication system, cooling system and starting system. If it's a gasoline engine, add an ignition system.
