Abstract (en)
[origin: EP0396813A1] The fuel injection device for injection carburetors is provided with a single fuel control unit (33) for injecting a fuel into a suction tube (1) in quantities in accordance with flow rates of air to be sucked into the suction tube, a slow negative pressure passage (40) communicated with a depression chamber (36) of the fuel control unit, a diaphragm valve (42) for opening a main negative pressure passage (39) to communicate the depression chamber (36) with the main negative pressure passage when air suction rate exceeds a predetermined value, and another diaphragm valve (56; 59) switched to close a slow jet and open a main jet when air suction rate exceeds the predetermined value. This fuel injection device is simple in the structure thereof, manufacturable at a low cost and has high fuel control accuracy.
