Components of the engine (summary of engine structure and okx.com loginits components) The engine is the most core part of internal combustion machinery such as automobiles. It is responsible for converting chemical energy into mechanical energy and driving the car.The structure of the engine is very complex and contains many different parts. Next, we will introduce the structure of the engine and its components. 1. Cylinder block is one of the most important components. It carries other parts of the whole engine and is the installation position of the cylinder. The cylinder block is usually cast into one, and the material is often cast iron or aluminum alloy. The oil channels, waterways and airways in the cylinder block do not interfere with each other and are independent of each other to ensure the circulation of good lubrication, cooling and compressed gas during the normal operation of the engine. Two. The cylinder head is installed above the cylinder block and provides a seal between the cylinder block and the outside world. It also provides sockets for ignition plugs and rocker arms, as well as cylinder head bolts and spark plug heaters. The cylinder head is also one of the important guarantees of processing accuracy. 3. Piston piston is one of the components that play a key role in engine operation.It moves back and forth in the cylinder block to convert chemical energy into mechanical energy. The material of the piston is often high-strength cast aluminum or heat-resistant alloy. The protruding part of the top of the piston is called the top of the piston, which is one of the upper parts of the combustion chamber. The piston ring is mainly divided into oil ring and air ring, which plays a role in maintaining the tightness of the cylinder block and the piston. Four. The crankshaft is one of the core components of the engine. It connects various pistons and converts their linear motion into rotational motion. The manufacturing technology requirements of crankshafts are extremely strict, and they are usually made of high-quality alloy steel. 5. Flywheel flywheel is a component that connects the engine and the transmission. Its main function is to balance the rotational inertia of the whole engine, and it will have an impact on the start-stop, acceleration and speed change of the engine. 6. The valve and valve mechanism The valve and valve mechanism play an important role in the compression and emission of the engine.The valve can control the inlet and out of air and fuel, while the valve mechanism can ensure the opening and closing of the valve and the rise and fall of the valve. Common valve mechanisms include camshafts and rocker arms. 7. Ignition device The ignition device is mainly responsible for igniting sparks in the mixed gas in the cylinder. Its main parts include spark plugs, ignition coils, ignition control boxes, etc. The ignition device should be kept clean from time to time to ensure normal working effect. Eight. The fuel system of the fuel system engine is mainly composed of fuel pump, fuel injector, fuel storage and other components. Together, they deliver fuel to the combustion chamber of the engine to ensure normal operation. Nine. Lubrication system The lubrication system provides lubrication for the operation of the engine to ensure that each component can run smoothly in the environment of high-speed friction. It includes lubricating oil pump, oil filter, oil temperature indicator and other components.10. The cooling system is responsible for effectively transferring and removing the additional heat generated in the engine to prevent damage caused by overheating of the engine. It usually includes components such as radiators, pumps, water pipes and coolants. In a word, the engine is one of the most core parts of the car. The operation of the engine structure and its components involves dozens of technologies, knowledge and sophisticated mechanical processes. Therefore, when maintaining, using, maintaining and overhauling the engine, it is necessary to operate strictly in accordance with the manufacturer's recommendations and requirements to ensure normal operation.
