Question

Quizplus · Accepted Answer

Coolant temperature is often a primary reference for the engine management software when determining timing and air/fuel ratio because it can give an indication of the engine's operating conditions and load. This information can be used to adjust the timing and fuel injection timing to optimize performance and reduce emissions. Coolant system pressure, coolant level, and coolant flow rate may also be used as references, but are not typically as important as coolant temperature.
