ELECTRONICALLY CONTROLLED FUEL INJECTION APPARATUS

摘要

In an electronically controlled engine supplying fuel from a fuel injector near an intake port to an intake system, asynchronous acceleration fuel injection is carried out in relation to the secondary differential d2X/dt2 of intake pipe pressure or intake air flow rate with respect to time t. Since the d2X/dt2 increases rapidly and accurately after the start of acceleration of the engine, the asynchronous acceleration fuel injection can be carried out rapidly and accurately.
