Abstract

PURPOSE: To properly control at a high land a low load running of a Diesel engine with a suction air shutter device for throttling an amount of suction air during a low load running of the engine by providing the engine with means for moderating throttling of the suction air shutter device during running of the engine at a high land.
CONSTITUTION: During an idling running of a Diesel engine at a level ground, an accel pedal 24 is in a closed position, and a magnet valve 17 adapted to be open upon operation of an exhaust gas brake and an opening and closing valve 19 adapted to be open during running at a high land are both closed. A cross valve 10 is thereby opened and thus negative pressure is introduced into a power chamber 8 from a vacuum chamber 13 so that a suction air shutter 4 is pivoted to its closed position by a diaphragm 8b through a link mechanism 6. On the other hand, during running at a high land, gas within a bellows 34 of a high land correcting device 32 is allowed to expand itself so that the bellows 34 are extended against a spring 35 to close a switch means 40. The opening and closing valve 19 is thereby opened to establish communication of a bypass passage 20 so that throttling of the shutter device is varied thereby.
