Basic parts of a engine The core of the engine is the cylinders, it is made up of the head and block of you engine. Piston: A piston is a cylindrical piece of metal that moves up and down inside the cylinder. Spark plug: supplies the spark that ignites the air/fuel mixture so that combustion can occur. The spark must happen at just the right moment for things to work properly. Valves: The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. Note that both valves are closed during compression and combustion so that the combustion chamber is sealed. Crankshaft: The crankshaft turns the piston's up and down motion into circular motion just like a crank on a jack-in-the-box does. Oil pan: The oil pan I just used to hold oil, also know as the slump. Fuel Injectors: Fuel injectors push fuel into the engine, in newer cars, older cars have carburetors.

Inside an engine Parts of an engine

What makes a car move? The car battery powers up sending Power to the starter motor, which Turns the crankshaft, which Starts the pistons moving With the pistons moving the engine fires up and ticks over A fan draws air into the engine via an air filter The air filter removes dirt and grit from the air The cleaned air is drawn into a chamber where fuel (petrol or diesel) is added This fuel-air mix (a vaporized gas) is stored in the chamber The driver presses the accelerator pedal The throttle valve is opened The gas-air mix passes through an intake manifold and is distributed, through intake valves, into the cylinders. The opening and closing of the valves is controlled by the camshaft. The distributor makes the spark plugs spark, which ignites the fuel-air mix. The resulting explosion forces the a piston to move down which in turn causes the crankshaft to rotate.shaft to rotate.

Internal combustion The ­principle behind any reciprocating internal combustion engine: If you put a tiny amount of high- energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. If you can create a cycle that allows you to set off explosions like this hundreds of times per minute, and if you can harness that energy in a useful way, what you have is the core of a car engine! The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work. Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful.When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down.Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to go out the tailpipe.
