Abstract

PURPOSE: To carry out exhaust gas purifying, by combining EGR equipment and carburetor with built-in auxiliary fuel equipment.
CONSTITUTION: With co-idling, at light load running, throttle valve 28 of the carburetor 3 is almost shut, the negative pressure in the suction manifold 2 is large, since the contact point 32 of negative pressure switch 30 is opened, all solenoids 26, 37 among solenoid valve 21, 31 will be not energized. Then an inlet port 24 of solenoid valve 21 is shut with the valve body 25, the negative pressure does not work to the diaphragm chamber 18 in EGR valve 13, EGR does not carry out. While, on the solenoid valve 31, since part 35 on atmospheric air side is shut, condiut 38 from suction manifold 2 is connected to the negative pressure chamber 49 of the power equipment 8 through the inlet and outlet ports 34, 39 and the conduit 40, the passage 44 is off, so that air fuel ratio will be lean.
