Desel >Dual > Otto.

Option is not correct,

Otto cycle is more efficient then other two cycles i.e. dual and diesel cycle.

Efficiency of dual cycle is more then of diesel cycle but less then Otto cycle.

So high efficiency is Otto cycle.

Least efficiency is diesel cycle.

Otto >dual >diesel cycles.

Yes, agree @Basha Khan.

You are right @Krishna.

For increasing order:

Diesel> Dual>OTTO.

Mohan said:   7 years ago
Diesel > dual > otto.

For compression ratio the order should be reversed.

Baswa girish said:   7 years ago
Diesel<Dual<Otto.

Shivam said:   6 years ago
Yes, you are right @Krishna.

Otto cycle is more efficient to diesel cycle and dual cycle is always lies b/w otto cycle and diesel cycle then:

Otto>dual>diesel.

I think it is about heat addition at constant pressure so duel cycle is Also known as limited pressure cycle so duel, diesel, petrol.
