It should be like a diesel dual Otto.

For same compression ratio and heat input efficiency comparison between cycles--Otto>duel>diesel.

And for constant pressure and temperature dual have more efficiency than diesel and otto.

At same compression ratio. Otto>dual>deisel.
At max pressure and temp. ie(diesel have max pressure at max compression ratio which is 15:1 and otto will have max pressure at max compression ratio which s 7:1). So here Diesel will have more efficiency than dual.

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

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.
Otto>dual>diesel.

Yes, you are right @Krishna.

Diesel<Dual<Otto.

Diesel > dual > otto.
For compression ratio the order should be reversed.

For increasing order:
Diesel> Dual>OTTO.
Diesel> Dual>OTTO.
