I got this question in a job interview.

This interesting question is from Reducing Emissions by Chemical Methods in portion Engine Emissions and their Control of IC Engine

Answer 1

The correct answer is:

(a) True

Exhaust Gas Recirculation (EGR) is done by ducting some of the exhaust flow back into the intake system. This process helps reduce nitrogen oxide (NOx) emissions by lowering the combustion temperature and oxygen concentration, leading to a more complete and controlled combustion process.
