    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).

    摘要: Turbines and compressors, which constitute superchargers, are disposed in series on an exhaust gas passage and an air intake passage, respectively. The supercharger is equipped with a supercharger rotation sensor, which transmits a detection signal obtained according to the rotation of the compressor to a control device, a bypass passage, which bypasses exhaust gas from the upstream side to the downstream side of the turbine, and a bypass valve, which regulates the flow rate of exhaust gas flowing through the bypass passage. Control device regulates the rotational speed of the compressors in a high-efficiency range by producing a control signal based on the detection signal from the supercharger rotation sensor, and sending the control signal to the bypass valve.

    摘要: Turbines (21b, 31b) and compressors (21a, 31a), which constitute superchargers (21, 31), are disposed in series on an exhaust gas passage (3) and an air intake passage (2), respectively. The supercharger (31) is equipped with a supercharger rotation sensor (61), which transmits a detection signal obtained according to the rotation of the compressor (31a) to a control device, a bypass passage (4), which bypasses exhaust gas from the upstream side to the downstream side of the turbine (31b), and a bypass valve (34), which regulates the flow rate of exhaust gas flowing through the bypass passage (4). Control device (60) regulates the rotational speed of the compressors (21a, 31a) in a high-efficiency range by producing a control signal based on the detection signal from the supercharger rotation sensor (61), and sending the control signal to the bypass valve (34).
