Piston Ring

The function of a synchronizer is to enable meshing gears to be changed, on a moving vehicle without negative consequences for gears mechanical integrity and interior noise. During synchronization the friction clutch must be disengaged.

A cylinder sleeve (also called cylinder liners or engine sleeves) is a cylindrical metal engine component that protects an engine’s bore and can be used to create bore dimensions after an engine has been over-bored or modified.

A glow plug is a heating element that heats incoming fuel and air to encourage efficient fuel combustion in a diesel engine. The fuel combustion starts your engine so that you can drive.

It’s the fuel pump, and its job is to pump fuel into the engine and to maintain a certain fuel system pressure. It may be smaller than many parts in your car, but it actually plays a huge role in the operation of your engine.

A disk or short cylinder fitting closely within a tube in which it moves up and down against a liquid or gas, used in an internal combustion engine to derive motion, or in a pump to impart motion.

In a piston engine, the main bearings are the bearings which hold the crankshaft in place and allow it to rotate within the engine block. Main bearings are usually plain bearings or journal bearings, held in place by the engine block and bearing caps.

Valve stem seals prevent oil from contaminating the air/fuel mixture in the engine’s combustion chamber. They also prevent intake and exhaust gases from contaminating the oil in the cylinder head and the rest of the engine. Valve stem seams are like any other round seal, only much smaller.

A diesel fuel lift pump is a priming pump that transfers fuel from the tank to the fuel injection system. They are called lift pumps, because in most equipment the tank is located below the engine, the fuel has to be lifted up from the tank to the engine.
