Engine Components & Functions

Spark Plug: Ignites the fuel air mixture in the cylinder

Inlet Valve: Opens at the correct time to allow fresh fuel to get into chamber then closes

Exhaust Valve: Opens at the correct time to allow the exhaust gasses out

Piston: Pushes air. Its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via piston rod and connecting rod

Gudeon Pin: Connects the piston to the connecting rod

Flywheel: Heavy wheel attached to rotating shaft to smooth out delivery of power from a motor to a machine

Piston compression rings: Forms a gas tight in the cylinder

Oil control ring: Controls the oil. Guarantees low friction and low consumption during operation


Crankshaft: Moves piston up and down via the crankshaft, transfers power to flywheel

Cambelt: Physical link between crankshaft and camshaft

Camshaft: Holds valves rockers in place,open and close valves, turns the pullies

Sump: Holds the oil

Oil strainer: Removes larger particles of carbon from the lubrication system

Petrol fuel injector: Sprays fuel into the inlet manifold mixes with the air.then into the cylinders. Injectors are a solenoid operated valve which deliver fuel in a form of atomised spray

Ignition coil: Provides high intensity sparks at the spark plugs to ignite the fuel in the combustion chamber

Water pump: Circulates coolant around the engine

Cylinder liner: Cast iron liners are used in aluminium blocks. Some blocks dont need liners. Makes hard surface made up of heat resistant materials
