Thank you @Darshan.

Yes, you are right Thanks. @Darshan Bathani.

Naturally, the Self ignition temp of working fluid in diesel cycle is more. . So the Efficiency of diesel cycle is more than that of otto cycle. But if we consider both cycles run normally with same compression ratio the efficiency of otto cycle is more than that of diesel cycle.

I think this is wrong, the efficiency of diesel cycle is more than the Otto cycle.
