The efficiency of an Otto engine compared to that of a diesel engine, for the same compression ratio will be _______________?
Correct answer: B. More
- A. Less
- B. More
- C. Same
- D. Data insufficient to predict
Explanation
At the same compression ratio, the Otto cycle has greater efficiency than the Diesel cycle because heat addition at constant volume gives a more favourable ideal-cycle efficiency comparison. The Diesel cycle becomes competitive only under a different comparison, such as equal maximum pressure or equal heat input.
