A.
Same
B.
Less
C.
More
Answer
D.
More or less depending on power rating

Answer: Option C

Solution

Answer: Option C
Solution:
The air standard efficiency of an Otto cycle compared to diesel cycle for the given compression ratio is More. Otto cycle is more efficient than Diesel cycle for a given compression ratio. For constant maximum pressure and heat input, the air standard efficiency of gas power cycle is in the order
