摘要：
The present invention relates to an electronically-controlled fuel injector, for an internal combustion engine (1), comprising a downstream fuel injection valve (2) located near an air intake port of each cylinder or inside a cylinder, an air intake passage (6, 21) which bypasses the throttle valve (8) located upstream of the downstream fuel injection valve (2), and a fuel vaporizing section (30) including an upstream fuel injection valve (3), and a heater (4) which vaporizes fuel injected from the upstream fuel injection valve (3); and further having an air intake port located upstream of the throttle valve (8), air flow control section (10) for controlling an amount of air, said fuel vaporizing section (30), vaporized-fuel branch section (42) for supplying vaporized fuel to each cylinder, and a vaporized-fuel distribution passage (43) which extends from the vaporized-fuel branch section (42) to an opening (44) located in each air intake pipe (21) located downstream of the throttle valve (8).
摘要（中）：
本发明涉及一种用于内燃机（1）的电子控制燃料喷射器，其包括位于每个气缸的进气口附近或气缸内的下游燃料喷射阀（2），进气通道（6） （2）的上游的节流阀（8）和包括上游燃料喷射阀（3）的燃料汽化部分（30）以及使燃料汽化的加热器（4） 从上游燃料喷射阀（3）喷射; 并且进一步具有位于节流阀8上游的进气口，用于控制空气量的气流控制部分10，所述燃料汽化部分30，用于供应汽化的汽化燃料分支部分42， 燃料向各气缸供给，从气化燃料支路部（42）延伸到位于节气门（8）的下游侧的各吸气管（21）的开口部（44）的汽化燃料流通路（43） ）。
