Question

Volume of the ceramic structure of a converter is generally about twice the displacement volume of the engine.

(a) True

(b) False

I had been asked this question by my school teacher while I was bunking the class.

Query is from Catalytic Converters topic in chapter Engine Emissions and their Control of IC Engine

Answer 1

The correct answer is:

(a) True

The volume of the ceramic structure (or catalyst substrate) in a catalytic converter is typically about twice the displacement volume of the engine. This is to ensure sufficient surface area for the catalytic reaction to effectively reduce emissions.
