Explain and contrast the functionality of a two-stroke and four-stroke diesel reciprocating engine.  Sketch the main working parts, label them, and describe their functionality. Explain the difference in configuration if the fuel was instead petrol. Describe using sketches the two or four stroke cycle process.

IC engines

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
