For the same cylinder dimensions and speed, which of the following engine will produce least power?
Correct answer: C. Petrol engine
- A. Supercharged engine
- B. Diesel engine
- C. Petrol engine
- D. All of the above engines will equal power
Explanation
For equal cylinder size and speed, a petrol engine generally develops less power because its mean effective pressure is lower than that of a diesel engine, while supercharging increases power output. Thus the petrol engine is the least powerful of the listed choices.
