摘要： An ECU calculates peak-current arrival time (time elapsed before a detected current arrives at a target peak current), and calculates predetermined-current arrival difference time (time elapsed before the detected current becomes lower than a predetermined current after exceeding the predetermined current). The ECU uses a beforehand stored relationship between the predetermined-current arrival difference time and defined peak-current arrival time to calculate the defined peak-current arrival time corresponding to the latest predetermined-current arrival difference time. The ECU uses such defined peak-current arrival time to compare the latest peak-current arrival time with the defined peak-current arrival time (for example, calculates a difference between the peak-current arrival time and the defined peak-current arrival time), and thus determines a shift in detected current of a current detection circuit.

摘要： Fuel injectors are disclosed that are capable of simultaneously delivering liquid and gaseous fuels to the combustion chamber of a compression ignition engine. For example, fuel injectors are disclosed that can deliver liquid diesel fuel, as a pilot liquid, along with a gaseous fuel, such as natural gas or other available fuels that are gases at atmospheric pressure and ambient temperature. The fuels are delivered to the needle control valve cavity sequentially via separate passageways. The delivery of the pressurized liquid fuel is actuated by the single actuator that is provided for each fuel injector. The actuator may be of a solenoid type or of a piezoelectric type or other suitable actuator as will be apparent to those skilled in the art. A liquid fuel check valve, in combination with the actuator, controls the delivery of the pilot liquid fuel to the needle control valve cavity.

摘要： A control system includes a fuel pump control module and a diagnostic module. The fuel pump control module controls a fuel pump to provide fuel to a fuel rail. The diagnostic module controls the fuel pump control module to provide a predetermined amount of fuel to the fuel rail, determines an estimated pressure increase within the fuel rail based on the predetermined amount of fuel, and compares an actual pressure increase within the fuel rail to the estimated pressure increase. The fuel pump control module selectively controls the fuel pump based on the comparison.

摘要： The invention relates to a fuel injection device with a multi-part injector body containing a pressure booster that can be actuated by means of a differential pressure chamber, and includes a pressure booster piston that seals a working chamber off from the differential pressure chamber. An on-off valve disposed above the injector body can actuate the fuel injection device. A pressure change in the differential pressure chamber occurs via a central control line that extends through the pressure booster piston of the pressure booster.
