Question

the intake system does all of the following except: a. prevent carbon dioxide from entering the engine. b. ensure that clean, dry air is supplied to the engine. c. provide a sealed passageway to the combustion chambers. d. control the amount of air entering the engine.

Explanation:

The intake system's main functions are to supply clean air (b), provide a sealed path (c), and control air amount (d). Carbon dioxide is a by - product of combustion and not something the intake system prevents from entering (as air already contains a small amount of \(CO_2\) and the engine's exhaust system deals with combustion - generated \(CO_2\)).

Answer:

A. Prevent carbon dioxide from entering the engine.
