Otto cycle is the standard of other cycles.

The efficiency of the Otto cycle is greater than the efficiency of the Diesel cycle for a given compression ratio and heat rejection.

Otto cycle > duel dycle > diesel cycle.

I think mechanical efficiency @Biren.

For same compression ratio, In case of diesel cycle heat rejection will be more compared to Otto cycle. (area under T-S dia, slope for constant volume is more than that of constant pressure) And since heat is rejected under conatant volume and added under constant pressure in case of diesel cycle, thermal efficiency of diesel cycle is less than that of Otto.

But which efficiency mechanical or thermal?

For the same compression ratio, the area under PV diagram is maximum for otto cycle. So the efficiency is the maximum for otto cycle followed by dual and diesel cycle.

Carnot cycle is more efficient than other cycle.

Otto cycle more efficient then other cycles.
