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.

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

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

For the constant pressure and heat input efficiency comparison between cycles--diesel>duel>Otto.

It should be like a diesel dual Otto.
