Abstract

PURPOSE: To prevent an output power of the engine from lowering down at an operation of rapid acceleration, by means of ceasing an operation of EGR for the time by a certain length only when made a rapid acceleration, in the EGR device with a countermeasure applied that an operation of the EGR be made at the time of high load operation of the engine.
CONSTITUTION: With the engine becoming a condition of rapid acceleration, a negative pressure in the air intake pipe is suddenly lowered. At this time, by an action of the negative pressure delay working valve 25, only a second chamber 26 is maintained at high negative pressure for a certain length of time, therefore, a negative pressure attraction force of the second chamber 26 overcomes a repulsive tension of the spring 30, to pull a rod 28 downward turning ON a switch 29. A signal of said switch 29 is inputted to a computer 11. Said computer 11 produces a command signal to make OFF a negative pressure switching valve 10 for a certain length of time after a detection of rapid acceleration of the engine, and then to return the negative pressure switching valve 10 to ON. Accordingly, for a certain length of time after the engine is rapidly accelerated, the closing of an EGR valve 5 makes no operation of the EGR, with a problem eliminated for the engine power output lowering down at the time of rapid acceleration.
