In an open/close control device 40 installed in a diesel engine 1, when a rotational speed N of the diesel engine 1 is equal to or higher than an intermediate rotational speed and a fuel injection amount is equal to or less than an idling injection amount Fi, a control portion 33 of a valve opening and closing controlling means 30 determines that the diesel engine is in such a state that engine brake is to be actuated, and controls to close both a bypass valve 24 and an EGR valve 52. Accordingly, since there is no fear that exhaust gas returns from an in...
The invention claimed is: 1. An open/close control device for an intake-exhaust communication circuit, wherein: the intake-exhaust communication circuit is equipped with: (i) a turbocharger having a compressor for sucking in and pressurizing fresh air to supply an internal combustion engine therewith and an exhaust turbine for driving the compressor; and (ii) a bypass line through which an outlet line of the compressor and an inlet line of the exhaust turbine communicate with each other such that part of intake air in the outlet line of the compressor ...
