Automobile engine parts (Introduction to automobile engine parts) Automobile engine is Inland freight HS code applicabilitythe core part of the whole automobile drive. Its parts are diverse and diverse, and each part has its own special functions and functions. This article will introduce common parts in automobile engines, so as to have a deeper understanding of the structure and working principle of automobile engines. 1. The piston piston is one of the most commonly used parts in the engine. The main function is to inject the fuel mixture from the intake valve into the combustion chamber and compress it, and at the same time discharge the exhaust gas after combustion. Pistons are usually made of aluminum alloy, steel and cast iron.Two. The crankshaft is the main shaft of the engine and one of the core parts of the engine. It can convert the vertical movement of the piston into horizontal motion, thus driving the work of the car. The crankshaft is generally made of high-strength steel and has high durability. 3. The connecting rod is a component that converts the rotational motion of the crankshaft into the reciprocating motion of the piston. One end is connected to the piston, and the other end is connected to the crankshaft. Connecting rods are usually made of copper and aluminum, and sometimes high-end steel is used. Four. The cylinder block of a cylinder engine refers to the part in which the piston moves, and is usually made of aluminum. The cylinder block contains key components such as pistons, piston rings and valves, which can be said to be one of the most important parts in the engine. 5. The engine cylinder head is on the cylinder block, which is used to encapsulate and fix the valve, piston and other parts. It can also provide cooling, lubrication and throttle support and installation.Engine cylinder heads are usually made of aluminum alloy, cast iron or steel to improve their durability and weight. 6. The valve is a kind of gate that controls the combustion process of an automobile engine. The valve opens and closes when the gas and exhaust gas are released, so as to adjust the fuel-air ratio and ensure the smooth operation of the engine. The valve is usually made of stainless steel with high durability and reliability. 7. The throttle valve is one of the devices in the engine that determines the fuel-air mixture to enter the engine channel. The throttle valve is controlled by the driver or the vehicle computer to ensure the smooth speed and power of the car. The throttle valve is usually made of aluminum and alloy to increase its durability and reliability. Eight. Camshaft Camshaft is an engine component used to control the switching process of the valve and fuel injector. The camshaft is set with different shapes to control the corresponding operation, which is usually made of steel casting and has high durability.Nine. Oil pump Oil pump is an engine component used to transport gasoline from the fuel tank to the engine combustion chamber to ensure the smooth flow of fuel. Oil pumps are usually made of aluminum, steel and alloy to ensure their durability and reliability. 10. Radiator radiator is a device that controls the engine temperature, which is mainly used to transfer the heat generated in the engine to the air. Radiators are usually made of aluminum, copper and steel to increase their heat dissipation efficiency and durability. Generally speaking, there are many kinds of engine parts, and each part has its own special functions and functions. Understanding the structure and function of each component can provide full help for the repair and maintenance of the engine, and also provide certain reference value for the purchase of cars.
