Abstract

PURPOSE: To provide an operation correctly without a delay of response simultaneously with an acceleration starting, by means of providing a switching mechanism for compensating a delay of initial operation.
CONSTITUTION: With an operation of the engine being shifted to an acceleration running, the rotational speed of the engine exceeds the first set value and a common contact 1a of the first switch 1 is made connected to 1c. Accordingly, both of the first switch 1 and the second switch 2 become in a state of operation, with the power fed from a power source B to a second solenoid valve 37 of exhaust gas return flow device 30 and to a third solenoid valve 52 of auxiliary fuel supply device 40. In consequence, a negative pressure of air intake is led into a negative pressure chamber 33c of the diaphragm device through a conduction pipe 35, with a flow control valve 32 lifted to start an operation of exhaust gas return flow. Simultaneously, with a negative pressure passage 51 closed by the valve 52, the atmospheric pressure is inducted to a negative prssure chamber 49, to open an on-off valve 45 and auxiliary fuel passage 44, and an increase of fuel quantity, fed to the main fuel passage 43, will ensure a high output.
