We know that when the engine returns back to the stroke where it starts we say that one cycle has been completed. In internal combustion engines, when the IC engine is working continuously, we may consider a cycle starting from any strokes. The IC engine has a higher thermal efficiency than the thermal efficiency of EC engines. In IC engines (internal combustion engines) the combustion of takes place inside the cylinder, therefore the thermal energy of the fuel is directly converted into mechanical work. Working Principle of Internal Combustion Engines

The main function of the flywheel is to maintain speed constant.It is a big solid wheel mounted on a crankshaft of an IC Engine.It also serves as a sump (storing place) for lubricating oil.It holds the cylinder and crankshaft of an engine.The function of the crankshaft is to convert the reciprocating motion of a piston into rotary motion with the help of connecting rod.The function of Connecting Rod is to transmit the force from piston to crankshaft.It is a link between the piston and the crankshaft.The exhaust valve is used to expel burnt gases from the cylinder.Inlet valve is used to take the fresh mixture into the cylinder.These are provided on the cylinder head,.Read also: Piston Rings: Types of Piston Rings 5. The rings are provided with an airtight seal.They retain elastic properties even at a higher temperature.Two sets of rings are provided, with an upper ring to prevent leakage of burnt gases into the lower portion, while lower ring to prevent leakage of oil into the Engine Cylinder.these are housed in circumferential grooves of the piston.These are circular rings made up of special steel alloys.The main function is to transmit force exerted by burning of charge to connecting rod.A copper or asbestos gasket is provided in between the cylinder and the cylinder head to make it airtight.It is made up of steel or aluminum alloys.Cylinder Head is fitted at the top of the cylinder.It will withstand high pressure and temperature.In this Piston makes to and for a motion to develop power.The cylinder is made up of steel or aluminum alloys.V-type Engine Parts of Internal Combustion Enginesįollowing are the main parts of IC engine:.Types of Internal Combustion Enginesįollowing is the list of type of IC Engines (Classified according to different method): Internal combustion engines – If the combustion fuel takes place inside the engine cylinder, it is an internal combustion engine. Ex: Steam turbine, Gas Turbine, Steam Turbine etc. External combustion engines – If the combustion of fuel place outside the engine cylinder, it is an external combustion engine.
