Abstract: Disclosed is a controller for a turbocharged engine. The engine includes a supercharger configured to supercharge intake air using an exhaust gas from the engine, and including movable flaps arranged so that a boost pressure generated in an intake passage is adjustable. If a rotational speed of a turbine and compressor that constitute the supercharger has reached a first threshold lower than an endurance limit, an amount of fuel injected to the engine is reduced to a predetermined amount. If the rotational speed has reached a second threshold lower than the first threshold, the amount of fuel injected is reduced in accordance with an excess of the rotational speed over the second threshold.

Abstract: An exhaust system device (1) for a vehicle (100) comprises an exhaust purification device (18) and a first exhaust gas recreation (EGR) cooler (24). The exhaust purification device (18) is disposed with a central axis of a downstream-side end inclined downwardly toward a rear side of the vehicle (100). The EGR cooler (24) is provided so as to introduce exhaust from a downstream side of the exhaust purification device (18), is adjacent to the exhaust purification device (18) and fixed to the exhaust purification device (18), and is disposed such that a central axis of the EGR cooler (24) is inclined downwardly toward the rear side of the vehicle.

Abstract: An exhaust device for an engine includes an engine main body having a cylinder head provided with a manifold exhaust passage formed with a gathering exhaust port, a turbo supercharger, a catalyst device provided adjacent to the turbo supercharger, and a processing device disposed on the same side as the cylinder head surface of the engine main body. The processing device includes an exhaust gas processing device and an EGR device. The turbo supercharger guides exhaust gas discharged from the gathering exhaust port upward. The catalyst device includes a carrier, and a container which allows the exhaust gas to pass through a lower region of the carrier. The EGR device and the exhaust gas processing device are at least disposed below the catalyst device.
