制御装置。A diesel engine equipped with a supercharger that uses exhaust gas to drive a turbine to rotate a blower fixedly installed on a common shaft with the turbine, pressurizes intake air, and supplies it into the engine via an intake manifold. In the EGR control device, the first EGR passage communicates between the upstream side of the turbine and the downstream side of the blower, the second EGR passage communicates between the upstream side of the turbine and the upstream side of the blower, and the first EGR passage and the second EGR passage communicate with each other.
an intake air temperature sensor that detects the intake air temperature downstream from the EGR gas injection position; and a control means for controlling switching of a switching valve so that the EGR passes through a second EGR passage.
Control device.
