Question

Maximum torque is generated by an engine when ______________

(a) it runs at lowest speed

(b) it develops maximum power

(c) it consumes maximum fuel

(d) it runs at maximum speed

This question was posed to me during an interview.

My question is from Engine Performance Characteristics topic in chapter Measurements and Testing/Performance Parameters and Characteristics of IC Engine

Answer 1

The correct answer is:

(b) it develops maximum power

Maximum torque is typically generated at an engine speed that is lower than the speed at which maximum power is produced. However, when the engine is running at the point where it develops maximum power, it is also producing a significant amount of torque. This is generally the optimal operating point for performance in many engines, balancing both torque and power output.
