Question

The delay period depends upon temperature and pressure in the cylinder at the time of injection.

(a) True

(b) False

I got this question in quiz.

This intriguing question originated from Delay Period in chapter Combustion and Combustion Chambers of IC Engine

Answer 1

The correct answer is:

(a) True

The delay period indeed depends on the temperature and pressure in the cylinder at the time of fuel injection. Higher temperatures and pressures in the cylinder typically reduce the delay period because they help the fuel to vaporize more rapidly and reach the ignition point more quickly. Conversely, lower temperatures and pressures can lengthen the delay period, as the fuel may not reach the necessary conditions for ignition as efficiently. Therefore, both temperature and pressure are crucial factors in determining the length of the delay period.
