Option A is Wrong because efficiency is same for the temperature limit.

So, Option D is the Right answer.

What are reversible and irreversible engine?

Manoj said:   8 years ago
@ALL.

There is no any engine based on the reversible cycle.

The Reversible cycle is there but no reversible engine is there.

I think option A is the right answer.

Answer A is right. All reversible engine working under a same temperature maximum efficiency.

The reversible engine follows the carnot cycle. So it has max Efficiency.

Mukesh said:   6 years ago
D is correct option and A is incorrect because Otto cycle, diesel cycle, all are reversible but they have less efficiency then carnot cycle and also stirling and Ericsson cycle have equal efficiency to that of carnot cycle when regenerative is used.

Kumar said:   6 years ago
Option A is correct answer
