Abstract
PURPOSE: To take measures for exhaust gas control and reduce the vibration and noise during the idle running by a method wherein the suction throttling apparatus is jointly provided to the diesel engine equipped with the exhaust gas recirculation (EGR) device.
CONSTITUTION: To the diesel engine equipped with the EGR device is jointly provided the suction throttling apparatus consisting of the relay 17, which is ON or OFF by the operation of a starter switch 12 of the engine 1 or the like. When the relay 17, which is ON only in the case that all of each switches 12W16 are ON, is ON, an EGR valve 4 is shut to cut the recirculation of the exhaust gas E to the suction A, in other words the EGR function and the throttling of suction is performed by means of the operation of a suction throttling valve 8 actuated by a vacuum pump 11 through a power chamber 7 so that the suction negative pressure at the idle running of the engine 1 is throttled down to 100mm Hg, having a suction throttling effect. On the other hand, when the relay 17 is OFF, ports A and D, and B and C in a solenoid valve 9 are respectively communicated with each other to open the EGR valve 4 by means of the operation of the pump 11 to function the EGR action and to cut the function of the suction throttling valve 8.
