What is the advantage of controlling the air-fuel ratio to a stoichiometric ratio?
A) A stoichiometric ratio reduces the production of toxic emissions within the engine's cylinders
B) A stoichiometric ratio helps the three-way catalytic converter perform at its peak efficiency
C) A stoichiometric ratio increases the potential for performance when the engine is under heavy load
D) Both A and B

Question

Quizplus · Accepted Answer

A stoichiometric air-fuel ratio optimizes the combustion process, reducing the production of toxic emissions and allowing the three-way catalytic converter to operate efficiently by providing the ideal balance of air and fuel for it to reduce NOx, CO, and HC emissions effectively.
