Question

A pre-combustion chamber gives a shorter delay compared to an open type of combustion chamber.

(a) True

(b) False

The question was asked in semester exam.

My question comes from Delay Period topic in section Combustion and Combustion Chambers of IC Engine

Answer 1

The correct answer is:

(a) True

A pre-combustion chamber typically results in a shorter delay period compared to an open combustion chamber. This is because the pre-combustion chamber promotes more efficient mixing of air and fuel, which leads to a more controlled and quicker ignition process. In contrast, open combustion chambers can have longer delay periods due to less efficient mixing and a higher likelihood of uneven fuel-air distribution. The pre-combustion chamber aids in achieving more complete combustion and reducing the delay period.
