Claims (1)
高負荷用吸気通路と、主起開閉弁上流の吸気通路から分
岐し、上記２つの高負荷用吸気通路のいずれか一方に接
続される低負荷用吸気通路とを備えてなるエンジンにお
いて、 上記２つの高負荷用吸気通路を開閉弁下流において接続
し、該接続部に燃料噴射弁を設けるとともに、一端が上
記開閉弁上流の吸気通路に設けられたスロットルバルブ
上流ト接続され、他端が上、記燃料噴射弁の噴射孔近傍
に、その方向が低負荷□ 用吸気通路の接続された高
負荷用吸気通路方向に開口する燃料微粒化用空気通路を
設けたことを特徴とするエンジンの燃料噴射装置。[Scope of claim for utility model registration] Two high-load intake passages that are opened and closed by on-off valves that open when the engine is under high load; and two high-load intake passages that branch from the intake passage upstream of the main on-off valve. In an engine comprising a low-load intake passage connected to one of the two high-load intake passages, the two high-load intake passages are connected downstream of the opening/closing valve, a fuel injection valve is provided at the connection part, and one end of the high-load intake passage is connected downstream of the opening/closing valve. A throttle valve installed in the intake passage upstream of the on-off valve is connected upstream, the other end is at the top, and its direction is near the injection hole of the fuel injector, and its direction is connected to the intake passage for low load. 1. A fuel injection device for an engine, comprising a fuel atomization air passage that opens in the direction.
