摘要:A fuel injection apparatus for a diesel engine has a fuel injection pump forfeeding fuel under pressure and fuel injection nozzles provided in the engine to inject
fuel fed from the injection pump. A pressure sensor for detecting fuel pressure isprovided in a midway in a fuel line connecting the injection pump to the injection nozzles.An electronic control unit (ECU) computes the frequency of the pressure fluctuation offuel based on a detected value from the pressure sensor immediately after fuel isinjected from the injection nozzles. The ECU then computes a fuel bulk modulus basedon the result of the computation of the frequency of the pressure fluctuation. Based onthe computed bulk modulus, the ECU computes a fuel injection start and end time.Further, the ECU adjusts an instruction value for fuel injection control based on the resultof the computation of injection start and end, and controls the injection pump based onthe adjusted instruction value.
