How does an internal combustion engine ( ICE ) work?

Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work.

Main Parts of an Internal Combustion Engine

Today we will learn about main parts of an engine or more appropriately an IC Engine. An internal combustion engine is a heat engine in which combustion (burning of fuel) takes place inside the cylinder of the engine. A high temperature and pressure force generates after burning of fuel. This pressure force use to move the vehicle or rotate wheels by use of some mechanism.

In an engine many parts work together to achieve the goal of converting chemical energy of fuel into mechanical energy. These parts are bolted together and the combination of all these parts is known as engine. Today I am going to tell you about these parts and how they work so you can know the basic of automobile engine.

Main Parts of an Internal Combustion Engine:

1. Cylinder block

Cylinder is the main body of IC engine. Cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. The main function of cylinder is to guide the piston. It is in direct contact with the products of combustion so it must be cooled. For cooling of cylinder a water jacket (for liquid cooling used in most of cars) or fin (for air cooling used in most of bikes) are situated at the outer side of cylinder. At the upper end of cylinder, cylinder head and at the bottom end crank case is bolted.

The upper side of cylinder is consists a combustion chamber where fuel burns. To handle all this pressure and temperature generated by combustion of fuel, cylinder material should have high compressive strength. So it is made by high grade cast iron. It is made by casting and usually cast in one piece.
