A) the air-fuel mixture being evenly distributed in the combustion chamber
B) black smoke from the exhaust
C) a rich air-fuel mixture near the spark plug tip
D) None of these

Question

Quizplus · Accepted Answer

In stratified mode, the air-fuel mixture is intentionally made lean in most of the combustion chamber, but rich near the spark plug tip for easier ignition. Therefore, option C is correct as it describes the result of a GDI operating in stratified mode. Option A is incorrect as the air-fuel mixture is not evenly distributed in stratified mode. Option B is also incorrect as black smoke is usually a sign of incomplete combustion, which is not the goal of stratified mode. Option D is incorrect as there is a correct choice.
