Question

Quizplus · Accepted Answer

The L-Jetronic system, developed by Bosch, primarily uses air flow as the principal input to determine the amount of fuel to inject into the engine. This system measures the volume of air entering the engine using an air flow meter, and then calculates the required amount of fuel to maintain the correct air-fuel ratio.
