List of Car Engine Parts: The functioning

by admin

The heart of your vehicle is its engine. It is a sophisticated device made to convert the heat from burning gas into the force that rotates the wheels of the vehicle. It consists of the removable cylinder head and the lower, heavier cylinder block, which houses the majority of the engine’s moving parts.

We have mentioned the best car parts names below. The curated List of Car Engine Parts is made right for your car.

Cylinder block:

The cylinder block, also known as the engine block, is a crucial part of the engine’s structural foundation. The structure and main stationary body of the engine are made up of three parts that make up the cylinder block, cylinder head, and crankcase. This engine component has numerous holes for the cylinders’ containment as well as for water and oil flow paths for cooling and lubricating the engine. It is frequently made of iron or aluminium. Compared to oil flow pathways, water flow pathways are more extensive.



In comparison to other parts, pistons are the most crucial engine component. The piston is an internal rotating cylindrical plug. It helps to transform the pressure energy of fuel combustion into useful mechanical energy, which is then transmitted to the crankshaft via the connecting rod. For each rotation, the pistons in the cylinder move twice, up and down. Engines running at 1250 RPM have a piston velocity that causes them to rise and fall 2500 times per minute. Since the piston is constantly rubbing against the cylinder, piston rings help to increase compression and decrease friction.


Cylinder head:

The common materials for the cylinder head are cast iron and an alloy of aluminium. By using studs mounted to the block to connect the cylinder head and block, gaskets are used to create a tight, leak-proof seal. Each cylinder’s cylinder head, which is situated above it, contains a combustion chamber. It also has threaded holes for ports, spark plugs, valve guides, valve seats, and coolant jackets. 



The crankshaft, which is a component of the engine, is where power is obtained. It is one of the main power transmission mechanisms used by all engine components. The crankshaft is the main part of the transmission system that converts the reciprocating motion of the piston into a rotational motion with the help of a connecting rod.

An alloy steel that has been heat-treated is used to forge or cast the crankshaft. This component is composed of crankpins, weds, a balancing weight, main journals, and oil holes. Crankpin on the crankshaft is where the large end of the connecting rod is attached. The distance between the centre of the crankpin and the centre of the crankshaft accounts for half of the piston displacement during the stroke.


Cam shaft:

A camshaft is a shaft with cams attached to it. A cam is a piece of machinery that changes the linear motion of the follower from the rotating motion of the camshaft. The movement of a camshaft opens the valves. 

The camshaft is driven by the crankshaft. The number of teeth on the crankshaft gear is nearly half of the camshaft gear. Camshafts are made of alloy steel. The function of the camshaft is to change the rotating motion of the crankshaft into an up-and-down motion that regulates the movement of the lifters, valves, pushrods, and rockers. Additionally, it regulates when the valves open and close.


Timing belt:

A piston engine uses a timing belt to synchronise the rotation of the crankshaft and camshaft. This synchronisation allows the valves of the engine to open and close at the proper times proportionate to the positions of the pistons.

Another crucial component for preventing piston-valve contact in an interference engine is the timing belt or chain. Timing belts typically have teeth on the interior surface of the drive belt. As a timing chain, a roller chain is used. On a belt made of durable rubber, gears on the pulleys for the camshaft and crankshaft are engaged.


Engine valves:

Air-fuel mixture entering the cylinder and the combustion products leaving the cylinders must be controlled by engine valves. These are located where the engine cylinder’s inlet and outlet openings are. The valves are firmly seated in their seats when they are closed.

Additionally, while the engine is running, these components of car engines function as mechanical devices to regulate the flow of fuel, air, and exhaust gases into the cylinder head or combustion chambers. To allow gases to flow, the valves open, and then they close as a result of the spring’s force. They operate like this.


Intake and exhaust valves:

The charge (or air) that enters the engine for burning and the exhaust gases that exit the cylinder are both controlled and regulated by the inlet and exhaust valves, respectively. They may be contained by the cylinder heads as well as the cylinder walls. Sometimes, their heads resemble mushrooms.

Air and fuel are introduced into gasoline engines through the entrance valve. The intake valves on diesel engines, however, can only admit air. In either case, releasing exhaust gases is the exhaust valve’s main objective.
