Abstract
PURPOSE: To provide a condition of big EGR rate and rich air-fuel ratio at the time of acceleration, to hold the avove condition only for the time being at the time of constant speed after the acceleration, thereafter with the promotion made for EGR cut and lean air-fuel ratio, simultaneously with said operation made relating by a speed change step of the change gear.
CONSTITUTION: A second EGR port 26, opening to an air intake pipe 1 at the upstream side from an EGR port 9, is linked to a diaphragm chamber 21 of a richer 20 of negative pressure response type, for supplying fuel independently from the main fuel supply path at the upstream of carburetor throttle valve, by a negative pressure circuit 25, 25'. To the above circuit 25, 25', is inserted a solenoid on-off valve 27 for detecting a high speed change stage time of vehicle change gear to operate, as well as with a negative pressure delay valve 28 and a negative pressure control valve 29 linked and provided in the negative pressure circuit 25'. With one valve chamber 40 of the negative control valve 29 made open to the atmosphere through an air cleaner 14 and another chamber 42 linked to the EGR port 9, when in a travel of top shift, though the richer 20 and on-off valve 18 are instantaneously stopped, exhaust gas is returned a little amount through a path 16 for a little length of time.
