Dual cycle, Diesel cycle, Otto cycle it is increasing order.
Otto cycle has high efficiency because of low heat ignition. Is I am right?
Otto cycle has high efficiency because of low heat ignition. Is I am right?

None of the options are correct. It should be Diesel, dual and otto because if you plot a PV diagram you will find diesel has more area then comes dual and then otto.

Yes, agree with @Krishna.
Diesel > duel > Otto.
Diesel > duel > Otto.

Yes, I agree with you both @Krishna and @Ashish.

It should be Diesel < Dual < Otto.

It should be in descending order like otto, dual and diesel.

The efficiency of Dual cycle always lies in between that of Otto cycle and Diesel cycle. For same maximum pressure and heat input, heat rejection in Otto cycle is maximum and Diesel cycle is minimum.
Hence, efficiency order should be Diesel > Dual > Otto.
Hence, efficiency order should be Diesel > Dual > Otto.

In otto cycle, there is no const. Pressure process then how consider otto cycle efficiency?
