Diesel engine cylinder liner piston

The cylinder liner and piston are crucial components in a diesel engine. Here's a brief overview of each:

Diesel Engine Cylinder Liner

Function: The cylinder liner provides a surface for the piston to move up and down. It also helps in heat transfer and protects the engine block from wear.

Materials: Typically made from cast iron or steel, designed for high durability and heat resistance.

Types: Can be either dry (inserted into the engine block) or wet (in direct contact with coolant).

Diesel Engine Piston

Function: The piston moves within the cylinder liner, compressing the air-fuel mixture for combustion. It converts the energy from combustion into mechanical work.

Design: Features a dome shape to enhance combustion efficiency. It has rings that help seal the combustion chamber and control oil consumption.

Materials: Usually made from aluminum alloys for lightweight and strength.

Interaction

The piston moves down during the intake stroke, draws in air, and then moves up during the compression stroke, igniting the fuel for power.
