DESCRIPTION
A piston is a cylindrical component that moves up and down within the cylinder of an engine. The piston is typically made of aluminum alloy and is designed to withstand high temperatures and pressures. The 3970840 piston is specifically designed for use in diesel engines and features a dome-shaped head that helps to increase the compression ratio. Pistons are a critical part of any internal combustion engine, as they help to convert the energy generated by burning fuel into mechanical power that can be used to drive the vehicle's wheels. Proper maintenance of the piston, including regular oil changes and replacement as needed, can help ensure that an engine runs smoothly and efficiently over its lifetime.
