Today many vehicles make use of the internal combustion engine, however with slight variations according to vehicle types, having some added features or components. Developed in the 19th century, this type of engine still remains a popular choice and it continues to benefit from the technological advances in engineering. Sell Auto Parts ease your hunt of truck engine parts at the reasonable price and quality product.

Components of an engine


Camshaft is a type of rotating device or apparatus used in piston engines for propelling or operating poppet valves. Camshaft comprises of series of cams that regulates the opening and closing of valves in the piston engines.

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.


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 and 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 crank shaft

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.


Surrounding the crankshaft, the sump contains some amount of oil.

Engine oil system

Oil is one of the most necessary substances of an automobile engine. Oil is distributed under strong pressure to all other moving parts of an engine with the help of an oil pump. This oil pump is placed at the bottom of an engine in the oil pan and is joined by a gear to either the crankshaft or the camshaft. The different parts of engine oil system include: engine oil, engine oil cooler, engine oil filter, engine oil gaskets, engine oil pan, and engine oil pipe.

Conclusion note

The above explained parts are the mandatory engine parts which can be seen in any kind of engine. Maintenance of these things is a must for the smoother use of your vehicle.
