Automobile engine structure analysis diagram Automobile engine is UEFA TVone of the core components of the automobile and is the core part that drives the movement of the automobile. The shape and size of the engine are different not only because of different models, but also because of changes in factors such as power and power. The structural diagram of the car engine can describe in detail the function and interrelationship of its internal structure and components. This article will analyze the structure and function of automobile engines in detail. 1. Engine structure The automobile engine is mainly composed of the following parts: cylinder block, cylinder head, piston, connecting rod, crankshaft, valve, valve spring, camshaft and fuel injector, etc. The cylinder block is the first important part of the engine, which is made of cast iron or cast aluminum. It is a container with a lid that is in direct contact with the cylinder and is used to hold the cylinder and piston of the engine.The cylinder head is a cover located on the cylinder block, which is mainly used to close the cylinder and piston. It is also connected to the intake and exhaust systems, and controls the intake and exhaust through the valve and camshaft. The piston is a closed long cylinder, which is installed in the cylinder and connected to the combustion chamber. The movement of the piston is transformed into the bearing movement of the engine through the connecting rod and crankshaft. The main function of the connecting rod is to connect the piston and the crankshaft together and convert it into the bearing movement of the engine, so as to promote the normal operation of the engine. The crankshaft is another important part of the engine, which is made up of multiple connecting rods in series to form a whole. The main function of the crankshaft is to convert the bearing movement from the piston into rotational motion to drive the engine to work normally. The valve is an important part of the engine, which controls the on/off state of the valve through the rotation of the camshaft.The on/off state of the valve controls the process of the intake and exhaust system, which is the key to the operation of the engine. The valve spring is a spring located at the top of the valve. Its main function is to maintain the closed state of the valve by restoring the elasticity to maintain the normal operation of the engine. The camshaft is a major part of the engine. It is a long strip-shaped shaft composed of cams. The camshaft controls the opening/off state of the valve through operation, so as to control the inlet and out of the gas in the cylinder, and further control the power and speed of the car. The fuel injector is one of the important parts of the engine. Its main function is to inject fuel into the cylinder to mix it with air to form a flammable mixture and promote the normal operation of the engine. Two. The functional engine is one of the core components of the automobile. Its main function is to burn fuel into mechanical energy and convert it into the power and driving force of the automobile.The intake and exhaust work of the engine is the key to the normal operation of the engine. The on/off state of the valve controls the inlet and out of the gas, which ultimately affects the power and speed of the car. During the intake process, gasoline is sprayed into the cylinder through the fuel injector, and then the cylinder is added through the valve to mix with the air to form a combustible gas. Under high temperature and high pressure, the combustible gas catches fire and burns, generating explosive force, and pushes the piston down to push the connecting rod and crankshaft to operate normally, thus pushing the car forward. During the exhaust process, the gas burned in the cylinder is discharged and finally discharged into the external environment through the exhaust system to prepare for the subsequent intake work. 3. The structural diagram of the automobile engine shows the internal structure and function of the engine, and its complexity and importance are self-evident. Understand the engine structure diagramIt is necessary, because it can have an in-depth understanding of the working principle and structure of the engine, so as to better maintain the health of the car and maintain an efficient and accurate operating state. Finally, it should be noted that the car engine is a very complex system. Therefore, using appropriate automotive oil and following the maintenance plan of the user manual are important measures to maintain the normal operation of the engine.
