This engine makes four piston strokes i.e. NUMBER OF STROKES PER CYCLE: A) FOUR-STROKE CYCLE ENGINE: The internal combustion engine is having a widely diverse classification on the basis of different criteria.įollowing are the major criteria and their subdivisions on which an IC Engine is classified: 1. Various advancements are done nowadays like advancements in the design of the engine, fuel injection, materials to be used, etc to improve the fuel efficiency, less weight of the vehicle, less pollution, and lower emission. This cycle includes four processes: intake, compression, combustion and power stroke and exhaust. Most of the engine uses the four-stroke engine, which means four piston strokes are required to complete a cycle. (On the basis of the number of strokes): two-stroke engine and four-stroke engine. Afterwards, the engine sprays the fuel into the hot compressed air which causes the ignition.

Whereas, in the diesel engine, only air is introduced and then compressed. during the power stroke, combustion gases expand and push the piston. In the spark-ignition engine, the fuel is mixed with air and introduced into the cylinder during the intake process.Īs the piston compresses the mixture, there ignites a spark that led to the combustion process. (On the basis of types of ignition) : a spark-ignition gasoline engine and compression ignition diesel engine. cylinder, spark plug, valves, piston, piston rings, connecting rod, crankshaft, and oil pan(sump). The engine consists of various components viz. This engine is widely applied in automotive, aviation, power generation, etc. Learn more in an online course of IC engine Click hereĪ diesel engine is an example of it where the working fluid is air. It works on the principle that the charge is ignited inside a combustion chamber under very high pressure. I.C.Engine, an acronym for an internal combustion engine is the engine in which ignition and combustion of fuel take place inside the engine. Both IC and EC engines are of two types, i.e. These kinds of engines are popularly known as ‘heat engines’.Basically, engines are of two types, i.e.

The engine is a mechanical component that converts one form of energy (especially heat energy) into mechanical energy.

Afterward, energy conversion from one form to another was introduced, using a machine called ‘engine’. Then, animals were trained and their power was utilized to perform certain works. In primitive times, man’s muscles were the primary source of power for work. An internal combustion engine is an engine in which ignition and combustion of fuel take place inside the engine.
