Abstract
PURPOSE: To improve the durability of solenoid valves, each set to a negative pressure passage and an air passage communicated with a diaphragm chamber of an EGR valve, without sacrificing the maneuverability, by improving the control method of both valves.
CONSTITUTION: An EGR valve 4 set to an EGR passage 3 is equipped with a valve body 7 controlled through a diaphragm 5 by force of negative pressure which is introduced in a diaphragm chamber 8. This negative pressure is a synthetic product of atmospheric pressure and suction pressure from a negative pressure passage 11 and air passage 14, and is adjustable by controlling solenoid valves 10, 13 set to both passages 11, 14 through a controller 16 in accordance with the engine conditions. The controller 16 is so composed that it kills the solenoid valves 10, 13 if the deviation of a monitored value from a target value of the EGR valve conditions is below a given level, and raises the level if the engine is under high load.
