An ideal Diesel cycle is very close to an ideal Otto cycle. What is the main difference between the two air-standard cycles?  The Diesel cycle assumes constant pressure heat addition and Otto cycle has assumes constant volume.   The Diesel cycle assumes constant pressure heat rejection and Otto cycle has assumes constant volume.   Fuel injection and the compression ratio.   The Diesel cycle assumes constant volume heat addition and Otto cycle has assumes constant pressure.   The Diesel cycle assumes constant volume heat rejection and Otto cycle has assumes constant pressure.

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.
