The diesel cycle is very close to the otto cycle. what is a difference between the two air-standard cycles? a)-the diesel cycle assumes constant volume heat rejection and otto cycle has assumes constant pressure b)-the diesel cycle assumes constant pressure heat addition and otto cycle has assumes constant volume. c)-the only difference is the compression ratio. d)-the diesel cycle assumes constant volume heat addition and otto cycle has assumes constant pressure, e)-the diesel cycle assumes constant press constant volume heat rejection and otto cycle has assumes
