See More Photo: main Components of an Engine Spark Plug As mentioned earlier, gasoline engines make use of a spark to ignite the fuel and cause a controlled explosion in the engine. The spark plug in these engines supplies the spark that is required to ignite the air and fuel mixture. Valves These engine parts allow for fuel and air to enter the combustion chamber and later let the exhaust out. They remain sealed during the combustion process and only open when required. Pistons & Piston Rings This is a cylindrical piece of metal that is located inside the cylinder of the engine. Piston rings are located between the piston and the cylinder in which the piston is located in. They provide a sealing edge between the exterior of the piston and the interior of the cylinder. The purpose of these engine parts is to seal the space and prevent the fuel and air mixture on one side of the piston from leaking into the sump during the combustion or compression process and also prevent the oil in the sump from leaking into the combustion area as it would get burnt and lost, deterring the movement of the piston. Connecting rod and Crankshaft The connecting rod connects the piston to the crankshaft. As the piston moves up and down due to the controlled explosions, it causes the connecting rod to move. This then cause the crankshaft to move as well as it is connected to the connecting rod, in a circular motion due to the configuration of the piston, connecting rod and crankshaft.
