  • Car engine illustration: in-depth understanding of car engine structure and Precision instruments HS code verificationworking principle Car engine can be regarded as the heart of a car. It is responsible for providing power and converting the energy of the car into movement. Internal combustion engines are the main type of car engine at present, and the four-stroke gasoline engine is the most common type. This article will introduce in detail the structure and working principle of a four-stroke gasoline engine. Engine structure The four-stroke gasoline engine is composed of many different parts, and the work of these parts can ensure smooth operation. The following are the main components of the engine: 1. Cylinder: The engine usually has 4 to 8 cylinders.These cylinders are the confined chambers inside the engine, where fuel and air are compressed and burned to generate power. Two. Piston: The piston is a long strip-shaped part with a sealing ring that can move up and down in the cylinder. The upper part of the piston is connected to the connecting rod and the crankshaft, while the lower part is connected to the valve and oxygen tube. 3. Connecting rod: The connecting rod connects the piston and the crankshaft, and converts the movement of the piston into the rotation of the crankshaft. Four. Crankshaft: The crankshaft is a key part of the engine, which is responsible for transforming the up and down movement of the connecting rod into rotational motion. The cam on the crankshaft can operate the up and down movement of the valve. 5. Vale: The oxygen and fuel in the cylinder enter and leave the cylinder through the valve. The valve can be operated directly by the cam or controlled by a hydraulic device. 6. Fuel injector: The fuel injector can accurately spray gasoline into the cylinder according to the program in the car computer system.The above are the main components of the four-stroke gasoline engine, and the collaborative work of these parts produces the power of the engine. Engine working principle The operation of a four-stroke gasoline engine can be decomposed into four basic steps. 1. Intak stroke: The mixture from the valve into the cylinder is composed of gasoline and oxygen sprayed by the fuel injector. The piston moves from the upper part to the lower part, and the pressure in the cylinder becomes smaller, so that the mixture automatically enters the cylinder. Two. Compression stroke: When the valve is closed, the piston moves up to compress the mixture so that the engine is ready to burn. 3. Combustion stroke: At the highest point in the compression process, the electric spark ejected by the fuel injector detonates the mixture, causing the mixture to burn and release energy and heat. The high-pressure gas is explosive, pushing the piston down and the crankshaft to rotate. Four. Discharge stroke: The piston moves upwards from the lower part, and the compressed exhaust gas is discharged from the valve.The piston moves from the upper part to the lower part to complete a cycle. Generally speaking, this is the basic working principle of a four-stroke gasoline engine. The coordinated operation of the four-stroke converts the energy of gasoline into mechanical energy, and also releases a lot of exhaust gas. Many positive measures can reduce exhaust emissions, such as installing catalytic converters on vehicles or replacing high-efficiency filters. Conclusion The structure and working principle of the four-stroke gasoline engine are very important basic knowledge. This helps to understand how cars power and provides a starting point for explaining how to reduce atomization and save fuel for the engine. For those who want to go deep into the fields of car repair and maintenance, this knowledge is also an essential component.
