The global goods transportengine is the core component of modern vehicles, which plays a crucial role in vehicle performance and power output.The engine is composed of many parts, each of which has a specific function. This article will introduce the composition of the engine and the role of each component in detail. I. Piston system The piston system of the engine is usually composed of pistons, connecting rods, crankshafts and other components. The piston is one of the most critical parts of the engine. It can compress the mixed gas to make it more flammable. At the same time, it can also transfer the energy generated by the explosion from the combustion chamber to the engine crankshaft. The function of the connecting rod is to change the up and down motion of the piston into the rotational motion of the crankshaft, and output the rotating power of the crankshaft to the wheels to drive the vehicle. II. VALE SYSTEM THE VALE SYSTEM OF THE ENGINE IS USUALLY COMPOSED OF INTO THE INT PIPE, THE INTIN VALve, THE AIN INT DUCT, THE AIR FILTER AND THE EXhausT VALE AND OTHER COMPONENTS. The function of the intake valve is to inhale air and fuel by controlling the air intake to form a mixture, thus causing an explosion and starting the engine.The exhaust valve discharges the exhaust gas out of the engine, making the engine run more smoothly. III. Fuel system The fuel system of the engine is usually composed of oil tank, oil pump, oil nozzle, fuel injector, fuel tank pressure regulator and other components. Among them, the oil pump extracts the oil from the fuel tank and raises its pressure, while the fuel injector mixes the fuel into the combustion chamber in a certain proportion to support the operation of the engine. IV. Ignition system The ignition system of the engine is usually composed of storage battery, ignition plug, distributor, control module, high-voltage line and other components. The ignition system can turn off the ignition plug through the current before the engine starts to run, and then release the ignition plug until the engine rotates to a certain speed to cause an explosion and support the operation of the engine. V. Cooling system The cooling system of the engine is composed of water tank, water pump, radiator, cooling fan and other components.The function of the cooling system is to reduce the engine temperature and maintain the normal operation of the engine by circulating the coolant. VI. Lubrication system The lubrication system of the engine is usually composed of oil pump, oil filter, oil cooler, oil pressure regulator and other components. It can lubricate and protect each friction surface when the engine is running, reduce friction, and extend the service life of each part. In a word, the engine is a highly complex and sophisticated system. Only when the components cooperate with each other can it run normally like a perfect music box. Although these components are independent of each other, they are also interrelated, and the lack of any of them can affect the normal operation of the whole system. Therefore, in the process of daily use, we need to better understand and grasp the principle and characteristics of the engine in order to better protect them and extend the service life of the engine.
