Engine is the heart of a car. There are a multiple engine types. But, what are the basic engine parts? Engine is a complex machine built to convert heat from burning gas into the force that turns the road wheels. A spark ignites a mixture of petrol and compressed air inside a sealed cylinder causing it to burn and hence expand and thus provides power to drive the car.
Basic Engine Parts
The lower heavier section is the engine block, a casing for engines main moving parts like cylinders, pistons and crankshaft
The detachable upper cover is the engine head which houses the injectors, valves and spark plugs.
System that open/close inlet outlet port to control the flow of gases or fluids within an engine.
Easiest way to understand a valve is when you turn on a faucet (tap) to brush your teeth, you’re opening a valve that allows pressurized water to escape from a pipe.
Controls the valves to ensure timely opening and closing of ports
The nozzle and valve through which fuel is sprayed into a cylinder
Ignites the compressed fuel/air mixture by an electric spark in the cylinder. Delivers electric current from an ignition system to the combustion chamber to ignite the compressed fuel/air mixture while controlling combustion pressure.
Piston transfers force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod
Converts the reciprocating movement of piston into rotary movement
Easiest way to understand a crankshaft – In real life ‘paddles’ on a bicycle is the most basic form of ‘Crank’ – where the two levers that help to multiply the force supplied by our leg muscles as they pump up and down
