If the maximum pressure in both air-standard Otto and Diesel cycles is the same, then the relations for compression ration r and the efficiency η between the two cycles are
1
rDiesel > rOtto and ηDiesel > ηOtto
2
rOtto > rDiesel and ηDiesel > ηOtto
3
rDiesel > rOtto and ηOtto > ηDiesel
4
rOtto > rDiesel and ηOtto > ηDiesel
