摘要： A system for controlling a compression ignition engine includes: a speed obtaining section which obtains an engine speed; and an injection amount setting section which sets, in a start period after the start of cranking, a fuel injection amount to be injected by injectors in next and subsequent cycles. If an engine speed achieved by combustion in an (n−1)-th cycle is higher than or equal to a determination threshold value and lower than a lower limit of the resonance range, the injection amount setting section sets the fuel injection amount for the n-th cycle to a jump-over injection amount, and sets the fuel injection amount for the (n+1)-th cycle to a resonance induction reducing amount, which is smaller than the jump-over injection amount.

摘要： An assembly at least comprising a fuel injector for dual fuel operation of an internal combustion engine. The assembly includes a nozzle holder defining a fuel circuit and provided with a nose adapted in use to be in connection with a combustion space of an internal combustion engine, and first and second nozzles in communication with the fuel circuit in the nozzle holder for directly injecting liquid fuel into the combustion space of the internal combustion engine for ignition of a combustible mixture present in the combustion space. The first and second nozzles adjacent to the nose of the nozzle holder are interconnected by a cooling channel. At each actuation of a fuel pump upstream of the first and second nozzles, substantially a full volume of fuel pumped during actuation of the fuel pump is allowed to flow through the cooling channel and via the first and second nozzles.

摘要： A fuel pressure sensor diagnosis device includes an electronic control unit configured to drive a fuel supply device during electric traveling of a hybrid vehicle, to perform determination as to whether an output of a fuel pressure sensor is within a normal range after driving of the fuel supply device is started, and to perform a diagnosis to determine whether a malfunction has occurred in the fuel pressure sensor based on a result of the determination, the normal range being an assumed range of the output of the fuel pressure sensor in a case where the fuel pressure sensor normally functions and the fuel supply pressure is a prescribed upper limit pressure.

摘要： Various embodiments may include a method for operating a diesel-common-rail piezo-operated servo injector comprising: partially charging the piezo-actuator from a non-charged state at 0 V (method a); partially discharging the piezo-actuator from an already charged state to a remaining limited charge (method b); measuring the piezo-voltage with both methods and comparing the results; when the comparison demonstrates correspondence within a predefined threshold, using method b in ranges in which method a cannot be carried out; and when the comparison does not demonstrate correspondence within the predefined threshold, using method a without using method b.

摘要： An in-cylinder pressure detecting apparatus for detecting a pressure in a combustion chamber of an internal combustion engine is provided. The in-cylinder pressure detecting apparatus comprises a pressure detecting element mounted on a tip-portion of a fuel injection device which injects fuel into the combustion chamber, and an amplifying circuit unit having an amplifying circuit which amplifies a signal output from the pressure detecting element and outputs a pressure detection signal. An in-cylinder pressure detecting unit integrated fuel injection device is configured by integrating an in-cylinder pressure detecting unit with the fuel injection device. The in-cylinder pressure detecting unit includes the pressure detecting element, the amplifying circuit unit, and a connecting member connecting the pressure detecting element with the amplifying circuit unit. The in-cylinder pressure detecting unit integrated fuel injection device is mounted on the internal combustion engine.
