Engine parts name picture - Learn about car repair parts! With the widespread use of cars,DigiPlus the demand for car repair and maintenance is also increasing. The engine of a car is the core component of the vehicle, and its operation affects the performance of the whole vehicle. Therefore, it is very important for car maintenance to know the accessories of the engine in time. Here, let's learn about the names and functions of engine accessories.1. Engine gas distribution mechanism Engine gas distribution mechanism, referred to as gas distribution mechanism (also known as fuel injection injection system), is a system composed of crankshaft cam, valve, valve lifter, camshaft, intake and exhaust manifold, intake valve, exhaust valve, fuel injector, fuel injection pump and intake manifold. Its main function is to control the actual operation of the engine, so that gasoline or diesel is mixed with air in the correct proportion, resulting in explosive combustion, driving the vehicle forward, and achieving the purpose of power output. Two. Engine valve Automobile valve is the core component of the engine, with a total of two types of intake valve and exhaust valve. Its main function is to regulate the intake and exhaust volume. The intake valve controls the mixing ratio of air and fuel to discharge the exhaust gas, while the exhaust valve controls the flow of exhaust gas and forms a part of the negative pressure in the cylinder to achieve the purpose of absorbing the mixture into the cylinder and ensuring the normal operation of the engine.3. Ignition system Ignition system consists of the following parts: charging generator, battery, ignition switch, brake light switch, ignition coil, ignition plug, distributor, ignition accessories and safety devices, etc. Its function is to generate a certain current after mixing the fuel with air, further activate the electric spark at the end of the ignition plug, and make the mixture burn. The quality of the ignition system directly affects the operation of the car engine, and its stability, reliability, efficiency and other aspects need to be maintained at a certain level. Four. Air intake system The air intake system of a car mainly includes intake manifold, air filter and intake valve and other components, which is the channel for the whole fuel to enter the engine. The output power of the engine can be increased by adjusting the intake and increasing the intake pressure. The air intake system can effectively improve the operating performance and fuel economy of the car.5. Fuel system The fuel system of a car is mainly composed of fuel pump, fuel pipeline, fuel injector, regulator and other components. Its function is to provide fuel for the car engine, regulate the driving speed and the ambient temperature in the vehicle. Fuel is the power source of car operation, and reasonable fuel system settings can effectively improve the energy consumption and driving distance of the car. 6. The function of the cooling system is to provide a cooling medium for the engine, control the operating temperature of the engine, effectively reduce the heat loss of the car, and ensure that the engine will not fail due to overheating at high temperatures. The cooling system is mainly composed of radiator, fan, water pump, coolant and pipeline, etc. The above is a detailed introduction to some common names of engine accessories and their basic functions. Only by understanding these parts can we better repair and maintain the car and ensure that the car can run in the best condition.At the same time, any auto parts have a certain service life and need to be replaced in time to maintain the stability and durability of the car.
