    摘要: It is an object to provide an engine that makes it possible to constantly detect the number of rotations of a supercharger with a calculation load of an ECU reduced. An engine 1 is provided with an engine base 8 comprised of a plurality of cylinders and a turbocharger 7, a crank angle sensor 4, a turbo sensor 5 that detects rotations of the turbocharger 7 as pulses, an amplifier 11 that divides the pulses by an arbitrary division ratio and calculates the divided pulses, and an ECU 10 that judges a surge condition of the turbocharger 7, wherein the ECU 10 sets a predetermined position of a piston of each cylinder in a crank angle of the engine base 8 to count start timing of the divided pulses, outputs the divided pulses counted from the count start timing to the number of predetermined rotations as a first output, and judges that, if a difference between the first outputs at every cylinder is more than a predetermined value, the turbocharger 7 is in the surge condition.

    摘要: Provided is an engine capable of performing post-injection control with a proper fuel injection amount. The engine (1) comprises an engine body (10) equipped with a turbocharger (7), an engine rotational speed sensor (21), an acceleration opening degree sensor (24), a boost sensor (23), a turbo sensor (22), and an ECU (100) for performing post-injection control. The ECU (100) recognizes the rotational speed of the engine, the supercharging pressure, the load on the engine, and the rotational speed of the supercharger, and so performs the post-injection control that the rotational speed of the supercharger becomes equal to the target rotational speed of the supercharger calculated in the ECU (100).
