There are four processes in diesel cycle as follows:

1. Isentropic compression.
2. Constant pressure heat addition.
3. Isentropic expansion.
4. Constant volume of heat rejection.

Answer is duel cycle. Duel cycle only have these two process constant pressure and constant volume.

It's a dual cycle because, As the name implies it is a combination of Otto and Diesel cycles. So it consists of 1 isochoric, 1 isobaric and 2 isentropic processes.

Yes, in a diesel cycle heat addition is happened at constant pressure.
And fur gases axhausts at constant volume.

Correct answer is diesel cycle.

Soumya said:   4 years ago
Yes, correct answer is diesel cycle.

Mayur said:   4 years ago
The Correct answer is a diesel cycle.

The answer should be a diesel cycle because in dual cycle two constant volume and one constant pressure process.

What is a cycle?

Guru vk said:   8 years ago
It's a diesel cycle as it consists one const pressure where heat is supplied, one const volume where heat is removed ie cooling and two isentropic processes. One is for expansion, another one is for compression. It is also known as const pressure cycle.
