FUEL INJECTION DEVICE

Japanese Patent JP3886193

B2

PROBLEM TO BE SOLVED: To shorten the fuel injection time, to compensate for the difference of the distance between upper and lower fuel injection valves, and to simplify injection control.
SOLUTION: A nozzle part 23a of a first fuel injection valve 23 is drawn sideways and attached on a part downstream from a throttle valve 44 in an intake pipe 20, and a second fuel injection valve 36 is arranged on the upstream side of the throttle valve 44 and also above an opening part 42. The injection time can be shortened, the difference of the distance between both fuel injection valves can be compensated for, and control for the fuel injection valves can be simplified by performing injection of respective fuel injection valves for the approximately same time through a process of forming respective fuel injection valves into the approximately same characteristics and hastening the fuel injection start time of the second fuel injection valve 36 earlier than that of the first fuel injection valve 23, or by making a time lag so that the injection having the same amount of the first fuel injection valve 23 may be finished earlier than the second fuel injection valve 36 through a process of forming the fuel injection characteristic of the second fuel injection valve 36 so that the second fuel injection valve may inject fuel having the amount larger than that of the first fuel injection valve.
