Engine Components and Function

　Complete the following grid. Please elaborate on the function

Component	Function
Spark plug,	ignites the fuel air mixture in the cylinder
Inlet Valve	lets the fuel air mixture int the combustion chamber
exhaust valves	opens at the correct time to allow the exhaust gasses out
piston	transfers the force from the power stroke to the crankshaft
conrod	connects the piston to the connecting rod
flywheel	the flywheel links the crankshaft to the transmission through the clutch. The outer edge of the flywheel is called the ring gear. theelectric starter pinion engages on thisgear to rotate the engine for starting.
piston rings	forms a gas tight in the cylinder
oil control ring	Prevents oil working up into the combustion chambers
crankshaft	the crankshaft rotates in the main bearings in the crankcase. Connecting rods are attached to offset areas called throws where the reciprocating motion of the piston is changed into rotary motion.
cambelt or cam chain	physical link between crankshaft and camshaft
camshaft	opens and closes the valves through the rocker arm
sump	the is a sump a reservoir, or storage container, for the engine lubricating oil, and a collector for oil returning from the engine lubricating system.
oil filter	removes larger particles of carbon from the lubrication system
petrol fuel injector	Injectors are solenoid-operated valves which deliver fuel in the form of an atomised spray, into the intake manifold, or the intake ports.
ignition coil	The ignition coil is a step-up transformer, which raises the nominal battery voltage of 12 volts up to the many thousands of volts necessary to provide a spark across the spark plug electrodes
water pump	circulates coolant around the engine
cylinder liner	Cast iron liners are usually used in the cylinders of aluminium blocks, and sometimes in cast-iron blocks. Some sleeves are cast into the block. Grooves on the outside form a key that stops any movement in the cylinder. They also increase surface area to assist heat transfer from the sleeve to the block.
