The automobile engine is an engine for providing power for an automobile, is the heart of the automobile and influences the dynamic property, the economical efficiency and the environmental protection property of the automobile. According to different power sources, the automobile engine can be divided into a diesel engine, a gasoline engine, an electric automobile motor, hybrid power and the like. Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, and convert chemical energy of fuel into mechanical energy of piston motion and output power outwards. The gasoline engine has high rotating speed, low quality, low noise, easy starting and low manufacturing cost; the diesel engine has large compression ratio, high heat efficiency, and better economic performance and discharge performance than the gasoline engine. The engine is composed of two major mechanisms of a crank link mechanism and a valve actuating mechanism, and five major systems of a cooling system, a lubricating system, an ignition system, a fuel supply system, a starting system and the like. The main components include cylinder, balance shaft, cylinder head, piston pin, connecting rod, crankshaft, flywheel, etc. The balance shaft has the advantages that the engine works more stably and smoothly, the balance shaft technology is simple in structure and very practical, vibration of the whole vehicle can be effectively reduced, and driving comfort is improved. When the engine is in operation, the piston moves very quickly and at a very non-uniform rate. When the piston is located at the upper and lower dead center positions, the speed is zero, but the speed at the middle position of the upper and lower dead center positions is highest. Because the piston makes repeated high-speed linear motion in the cylinder, large inertia force is inevitably generated on the piston, the piston pin and the connecting rod. While the counterweights on the connecting rods can effectively balance these inertial forces, only a portion of the moving mass participates in linear motion and another portion participates in rotation. Therefore, except for the positions of the upper dead point and the lower dead point, other inertia forces cannot completely reach the balance state, the engine generates vibration at the moment, and the stability of the operation of the whole engine is influenced when more burrs are formed on the surface of the balance shaft.
