Friend, please refer to the diesel cycle and Otto cycle diagram for once. In the diagram above I have tried to plot both cycles in a same graph.S.mukherjeeQUOTE::"In a diesel cycle (referring to air standard cycle) heat addition occurs at constant volume. While in an Otto cycle, the heat addition occurs at constant pressure (again imagine an air standard cycle)"::
IssueCompression ratio is the ratio of the volumes which the engines can afford to compress.
It depends on various factors. It depends on metallurgical considerations while most important parameter in this context is the engine knocking.
For CI engines, it is called Detonation.
