![]() ![]() These rings are made of aluminum, having direct contact with the cylinder liner, thus preventing piston wear. There are three rings known as piston rings fitted in the circular recesses on the piston surfaces. The diameter of the piston is a bit less than the bore of the cylinder to avoid quick wear of the piston surface. The piston is a cylindrical part that moves upward and downward in the cylinder, allowing the complete combustion cycle to take place (intake, compression, combustion, exhaust) check out how this process works below. It allows coolant to enters and circulates to enables effective heat dissipation in the case of liquid-cooled engines. The cylinder block also contains some hollow space around and in between the individual cylinders, these hollow parts are known as jackets. the movement of the piston from the TDC to the BDC, they are the uppermost and the lowermost point of the stroke. The bore is the inner diameter and the stroke is the effective length along the piston reciprocates i.e. The cylinders have part or space for the piston to move upward and downward, making the combustion take place.Ĭylinders are characterized by their bore and stroke. This liner is worn out when subjected to work and can be easily replaced. It contains a liner or sleeves around it. ![]() These automobile engine parts are located in the engine block also known as the cylinder block. Components of Internal Combustion Engine:īelow are the common parts of an internal combustion engine: 1. ![]()
