Original Diesel Engine Cylinder Liner for Isuzu 4BE1

The cylinder liner is an important component in the engine, which together with the cylinder head and piston constitute the working space of the cylinder. The main functions of the cylinder liner have the following aspects.

First of all, the cylinder liner together with the cylinder head and piston constitute the working space of the cylinder. The cylinder liner is a barrel-shaped part that is installed in the engine block and acts as a separation between the piston and the block. Its inner diameter matches the piston diameter to ensure the reciprocating movement of the piston in the cylinder.

Finally, for a two-stroke diesel engine, the arrangement of the cylinder liner has another important function, that is, the realization of gas distribution. The cylinder sleeve is arranged with an air port, through the opening and closing action of the piston, to realize the inlet and outlet of the gas in the cylinder. During the working process, the cylinder liner works with the piston to control the flow of gas in and out to ensure the normal working rhythm of the engine.

In summary, the cylinder liner plays an important role in many aspects of the engine. It not only constitutes the working space of the cylinder, bears the side thrust of the piston, but also transfers heat to the cooling water, realizes the heat dissipation of the engine, and plays the role of the valve in the two-stroke diesel engine. The design and manufacture of cylinder liner has an important impact on the performance and life of the engine, so it needs to be paid enough attention in the design and production of the engine.
