Question

At constant speed, delay period is proportional to the delay angle.

(a) True

(b) False

I have been asked this question by my college director while I was bunking the class.

This key question is from Delay Period in portion Combustion and Combustion Chambers of IC Engine

Answer 1

The correct answer is:

(a) True

At constant speed, the delay period is proportional to the delay angle. The delay period is the time between the start of injection and the start of combustion, and this duration can be expressed as a delay angle in terms of crank angle. Therefore, at a constant engine speed, a longer delay period corresponds to a larger delay angle.
