ABSTRACT:
In a fuel injected internal combustion engine, the fuel injection is based on computation rather than direct measurement of air intake. To correct for air intake volume changes caused by external factors, a pressure sensor detects the pressure inside the exhaust manifold and, based on this detected value, a correction is made either to the computed value for air intake, directly to the computation of the amount of fuel to be injected, or both. The corrected air intake volume and the corrected fuel injection amount are then used as the basis for ECU control of the time power is applied to the fuel injector.
