초록 ▼

An apparatus and method for sensing the failure of hydraulically-actuated electronically-controlled fuel injector in a combustion engine is disclosed. An electronic controller senses the pressure of the hydraulic actuator fluid prior to injection and samples the pressure throughout a subsequent injection cycle. If the samples show an oscillation in the pressure of the hydraulic actuator fluid, then the injector has fired. Otherwise, the injector has failed.

대표청구항 ▼

A hydraulically actuated electronically controlled unit injector fuel system comprising: a hydraulically actuated electronically controlled fuel injector; a pressurized hydraulic actuator fluid connected to the hydraulically actuated electronically controlled fuel injector; an electronic controller electrically connected to the hydraulically actuated electronically controlled fuel injector; a first sensor associated with the pressurized hydraulic actuator fluid and connected to said electronic controller; a second sensor associated with an engine parameter and connected to said electronic controller; wherein said first sensor associated with the pressurized hydraulic actuator fluid produces a pressure signal; wherein said electronic controller produces an injection signal in response to a sensed condition of said engine parameter and responsively inputs a first pressure level from said first sensor; wherein said electronic controller calculates a second pressure level less than said first pressure level, periodically inputs said pressure signal from said first sensor and produces an injector fault signal in response to said pressure signal exceeding the second pressure level for at least a predetermined number of consecutive inputs; and wherein said electronic control does not produce said injector fault signal in response to said pressure signal falling below said second pressure level for at least one of said predetermined number of consecutive readings.
