    摘要: The purpose of the present invention is to provide an engine having a revision means which regulates rotation speed of each of cylinders while reflecting specific unevenness of rotation of each of the cylinders. With regard to an engine 2 having a plurality of cylinders wherein opening timing of each of injectors 3 can be controlled respectively, comprising an individual standard rotation speed output unit 30 which outputs individual standard rotation speed Nstdi of each of the cylinders following fuel injection of the corresponding injector 3 when all the injectors 3 are in normal state, an engine rotation speed sensor 6 which detects individual actual rotation speed Ni of each of the cylinders following the fuel injection of the corresponding injector 3, and a revision amount calculation unit 50 which calculates revision amount of fuel injection amount to each of the cylinders from the corresponding injector 3 based on difference between the individual standard rotation speed Nstdi stored in the individual standard rotation speed output unit 30 and the individual actual rotation speed Ni calculated by the engine rotation speed sensor 6.

    摘要: In an engine which may show a behavior where an engine speed is not always minimized after compression top dead center of a cylinder in which poor fuel injection occurred, the cylinder in which poor fuel injection occurred is detected. A common rail diesel engine (1) includes a individual reference number-of-revolutions output unit (30) for outputting the individual reference number of revolutions Nstdi of each cylinder corresponding to each injector (3) incident to fuel injection thereof, an engine speed sensor (6) for calculating the individual actual number of revolutions Ni of each cylinder corresponding to each injector (3) incident to fuel injection thereof, and fuel injection failure detection means for judging a cylinder temporarily judged as poor fuel injection as a cylinder of poor fuel injection when the plus and minus by a contrast arithmetic operation unit (80) coincide entirely in each cylinder and the absolute value |ΔNi′| of the difference in number of revolutions at the time of forced stop means is entirely above the absolute value |ΔNi| of the difference in the number of revolutions at the time of temporary judgment means.
