Mechanism of the engine (analysis and Arena plus APKinterpretation of the internal structure of the engine) The engine is the heart of modern vehicles and the core component that provides power. Its design and function are very complex, consisting of many subsystems and components. In terms of the mechanism of the engine, several important parts are involved. This article will do some analysis and interpretation of the internal structure of the engine. 1. The piston piston is a component of the engine mechanism originally introduced by the steam engine, which is made by casting or forging.It is one of the core components of the engine and is installed in the cylinder of the engine. The shape of the piston is usually cylindrical, the upper part is connected to the piston pin, and the lower part is connected to the connecting rod. The piston moves up and down during the engine to push the crankshaft. At the same time, a piston ring is also installed on the piston to prevent fuel and gas leakage. Two. The connecting rod is a key part connecting the piston and crankshaft, and its shape is usually T-shaped or H-shaped. Its main function is to convert the thrust from the piston into the rotational force of the crankshaft and transfer energy to the wheels. During the operation of the engine, the connecting rod keeps moving up and down and converts kinetic energy. 3. The crankshaft is another key component of the engine mechanism. It consists of a smooth steel shaft, one end of which is connected to a connecting rod and the other end is connected to the planetary gear group of the engine.The rotation of the crankshaft is converted by the thrust of the piston and the connecting rod, which makes the engine generate power. The crankshaft will be rotated many times, so it needs to be finely balanced to ensure the long-term stable operation of the engine. Four. The valve and the valve mechanism are the air outlet and inlet of the engine. The valve mechanism includes a series of rods, camshafts and valves. They work in coordination, opening and closing the valves to control the flow and pressure of the gas in the engine. Through the valve mechanism, the gas will be guided into and out of the engine cylinder block. 5. Fuel system Fuel system is another important component of the engine mechanism. It includes fuel injectors, oil pumps, filters and fuel tanks, etc. Fuel plays a decisive role in the engine because it is the source of explosive power. The fuel is finally sprayed into the cylinder block and burned in the combustion chamber of the engine to generate energy.In summary, these parts, known as the engine mechanism, are key elements for the normal operation of the engine. They work in a coordinated manner to convert chemical energy into mechanical energy and transfer energy from the engine to the wheels to push the vehicle forward. Therefore, the understanding and maintenance of the engine mechanism is of great significance to the appearance and maintenance of the vehicle.
