(b) 40-90%

(c) 50-100%

(d) none of the mentioned

I had been asked this question in final exam.

I want to ask this question from C.I. Engines in section Engine Emissions and their Control of IC Engine

Answer 1

The correct answer is:

(c) 50-100%

Platinum and palladium catalysts are highly effective in promoting the oxidation of carbon monoxide (CO) in the exhaust gases of internal combustion engines. These catalysts can typically remove 50-100% of the CO by converting it into carbon dioxide (CO2) through a catalytic oxidation process.
