Product Name: Piston With Rings for Mitsubishi Excavator Machinery Parts S4S
Technical Principles:
Material Composition: The piston is crafted from high-strength aluminum alloy to withstand the high temperatures and pressures encountered in excavator engines. The rings are made from durable materials with excellent wear resistance.
Compression and Combustion: The piston plays a crucial role in the combustion process. As the piston moves upward in the cylinder, it compresses the air-fuel mixture, preparing it for combustion when ignited by the spark plug. The piston rings maintain a tight seal between the piston and cylinder wall, preventing leakage of combustion gases and ensuring optimal compression ratios.
Heat Dissipation: The piston design includes cooling galleries and channels that help dissipate excess heat generated during combustion. This ensures the piston remains within safe operating temperatures and prolongs its lifespan.
Oil Control: The piston rings are responsible for controlling the distribution of oil along the cylinder wall. They scrape excess oil from the cylinder walls during the piston's downward stroke, preventing oil from entering the combustion chamber and minimizing oil consumption.
