Question

Quizplus · Accepted Answer

SFI (sequential fuel injection) meets the requirements of OBD II regulations because it allows for more precise control of the fuel injection process, which is necessary to meet the stricter emissions standards set by OBD II. This system injects fuel directly into each cylinder individually at the exact right time, reducing emissions and improving efficiency compared to other types of fuel injection systems.
