Aluminum alloy cast iron steel automobile piston
Automotive pistons are key components in internal combustion engines, and their performance directly affects the power, fuel economy, environmental performance, and other aspects of the vehicle. The following is a detailed introduction to automotive piston products:
- Structure: Automotive pistons are usually made of aluminum alloy or steel and have a cylindrical shape. Its structure can be divided into top, head, and skirt. The top is the main part that makes up the combustion chamber, with various shapes such as flat top, concave top, convex top, etc., to adapt to different combustion chamber forms and engine requirements. The spark plug at the head is connected to the cylinder head, while the bottom is tightly attached to the cylinder wall.
- Function: The main function of the piston is to convert the high-pressure gas pressure generated by fuel combustion into mechanical motion. Moving up and down in the cylinder, the car wheels are driven to rotate through the connecting rod and crankshaft mechanism. At the same time, the piston is also responsible for introducing the mixture of fuel and air into the combustion chamber and withstanding the effects of high-temperature and high-pressure gases during the combustion process.
Machining Precision:
Because the dimensional accuracy of the piston directly affects the performance and reliability of the engine. The dimensional tolerance requirements for pistons are extremely strict, generally within 0.01 mm. Even for some high-precision pistons, the tolerance is required to be within 0.005 mm. The accuracies of roundness, cylindricity, and straightness of the piston are also of great importance, ensuring the smooth movement and sealing of the piston in the cylinder. The requirements for mutual positional accuracy are also very high, ensuring the accuracy and reliability of the piston during assembly and use.
Machining Process:
Select an appropriate piston material, such as aluminum alloy, cast iron, etc. The material needs to undergo strict inspection and testing to ensure that its quality meets the standard. Conduct mechanical processing, including processes such as turning, milling, drilling, and grinding. These high-precision processing equipment and processes ensure the dimensional accuracy and shape accuracy of the piston. When necessary, heat treatment and surface treatment are carried out to improve its mechanical properties, wear resistance, surface quality and wear resistance.
Product Application:
Automobile pistons play an important role in automobile components. They bear gas pressure, transmit power, and form the combustion chamber. Piston rings also play the role of scraping oil and distributing oil, maintaining the lubrication and cleanliness of the cylinder wall and piston surface.
