Claims (1)
射弁を備えると共に、この噴射弁の先端部前方にアシス
トエア通路を介して燃料微粒化用のアシストエアを導入
するようにした内燃機関の燃料供給装置において、上記
吸気絞り弁を低負荷域から開き始める第１の絞り弁と、
該絞り弁にリンク機構等を介して連動し中、高負荷域か
ら開き始める第２の絞り弁とに分けて設けると共に、こ
−れらの絞り弁に対応して吸気通路も分割する一方。 上記第１の絞り弁を介装した吸気通路をアシストエア通
路としてその下流側端部を燃料噴射弁の先端部前方に開
口させたことを特徴とする内燃機関の燃料供給装置。[Scope of Claim for Utility Model Registration] At least one fuel injection valve is provided in the intake passage downstream of the intake throttle valve, and assist air for fuel atomization is introduced in front of the tip of this injection valve via an assist air passage. In the fuel supply system for an internal combustion engine, the first throttle valve starts opening the intake throttle valve from a low load range;
A second throttle valve that is linked to the throttle valve via a link mechanism or the like and starts to open in the middle and high load ranges is provided separately, and the intake passage is also divided in correspondence with these throttle valves. A fuel supply device for an internal combustion engine, characterized in that the intake passage in which the first throttle valve is interposed is used as an assist air passage, and its downstream end is opened in front of the tip of the fuel injection valve.
