The Trade data-driven portfolio managementfive major systems of the engine (detailed explanation of the five major systems of automobile engines) The automobile engine is a precision machine with multiple systems, which are closely connected to realize the operation and maintenance of the engine.These systems include cooling, lubrication, fuel, ignition and exhaust. In this article, we will introduce each system in detail to help you better understand the car engine. Cooling system Cooling system is one of the most important systems of automobile engines. Its main function is to manage the engine temperature and maintain the good working condition of the engine. The cooling system is usually composed of components such as water pumps, water tanks, radiators, water pipes, throttle valves and thermometers. The cooling system can transfer heat from the engine to the radiator, and then radiate the heat to the surrounding environment through air cooling. This cooling method is not only efficient but also relatively environmentally friendly. The function of the lubrication system is to add oil film between the moving parts in the engine to reduce wear and friction, thus prolonging the life of the engine. The lubrication system is usually composed of components such as oil pump, oil tank, oil filter, oil pipe and oil pressure indicator.The lubrication system must maintain the appropriate oil level and pressure to ensure that the engine does not produce too much wear when working at high speed and for a long time. Fuel system The fuel system is used to deliver fuel to the combustion chamber of the engine and ignite and ignite at a specific moment to drive the engine. The fuel system usually includes components such as fuel pump, fuel filter, fuel injector, injector electronic control unit (ECU) and fuel pressure regulator. In the fuel system, it is often necessary to replace the fuel filter, fuel pump, fuel nozzle, fuel filter and other parts to ensure the normal operation of the system. At the same time, pay attention to regular cleaning of the system and measuring pressure and flow to ensure the best performance of the fuel system. Ignition system The ignition system is used to generate sparks in the combustion chamber of the engine, ignite the air-fuel mixture, and drive the engine.The ignition system is usually composed of components such as ignition coil, ignition switch, spark plug and control unit. The parts that need to be replaced in the ignition system include the ignition plug and the ignition coil, and the ignition indicator light on the dashboard should also be kept normal. Exhaust system The exhaust system is used to exhaust the exhaust gas that has been burned from the engine. Emission systems are often used to meet relevant local emission standards and reduce environmental pollution. The exhaust system mainly includes components such as exhaust pipe, catalyst, exhaust pipe and silencer. They work together to discharge the exhaust gas from the engine and reduce the sound to the appropriate level. Summarizing the five major systems of automobile engines, it is very important to maintain normal operation to ensure the high performance and long life of the automobile. Replacing the key parts of the five major systems of automobile engines and appropriate maintenance can improve the efficiency of automobile engines while reducing maintenance and repair costs.
