ABSTRACTThe purpose of this Presentation is to make familiar with INTERNAL COMBUSTION ENGINE. The whole report is prepared after deep studying of Automobile IC-ENGINE. Since many books are available regarding to this but this Presentation is very helpful for our Knowledge purpose.

INTRODUCTION: =Heat engine : It can be defined as any engine that converts thermal energy to mechanical work output. Examples of heat engines include: steam engine, diesel engine, and gasoline (petrol) engine.

TYPES OF COMBUSTION ENGINE

In an Internal combustion engine, combustion takes place within working fluid of the engine, thus fluid gets contaminated with combustion products.Example : Petrol engineIn an External combustion engine, working fluid gets energy using boilers by burning fossil fuels or any other fuel, thus the working fluid does not come in contact with combustion products. Example: Steam engine

IC-ENGINES MAY BE CLASSIFIED AS :

Spark Ignition engines(SI).Compression Ignition engines(CI).

Spark ignition and Compression Ignition engine operate on either a four stroke cycle or a two stroke cycle.
