Abstract

PURPOSE: To reduce the load on an exhaust cleaner while maintaining the effect of engine bracking during deceleration, by providing some of carburetors with a mixture increasing unit which responds to boosting negative pressure.
CONSTITUTION: Boosting negative pressure is applied to a valve chamber 25 in the downstream part of a by-pass 19 and to the negative pressure chamber 26 of a mixture increasing unit M provided for a carburetor 31 which is one of ganged carburetors 31W33. With the strengthening of the negative pressure in pressure reduction, a valve element 21 is moved back because of the area difference between diaphragms 23, 24 and the by-pass 19 is opened so that air flows. Fuel is sucked out through an auxiliary nozzle 29 by the air flow to increase the quantity of mixture. The quantity of unburned substances in exhaust gas is decreased by the mixture increase to reduce the load on an exhaust cleaner. Since the throttle valves 9 of the other carburetors 32, 33 are set at the degree of idling opening, enough engine braking effect can be produced.
