Piston Ring

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.

The water pump pushes coolant from the radiator through the coolant system, into the engine and back around to the radiator. The heat that the coolant picked up from the engine is transferred to the air at the radiator. Without the water pump, the coolant just sits in the system.

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 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.

Oil pump gears are powered by the crankshaft and in high horsepower or high revving applications the stock oil pump gears can fail due to the increased harmonics, or oscillating of the gear from the added power and revolutions of the crankshaft.

The Clutch Disc or plate is a part of your vehicle’s manual transmission system that delivers power from the engine to the transmission. It is fitted between the flywheel and the pressure plate. It is made of highly durable steel or sometimes Kevlar, in high-performance vehicles.

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.

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.

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.
