Claims (8)

  1. 동일한 행정을 중복하지 않고 행하는 복수의 기통으로 이루어진 내연기관의 흡기다기관에, 이 흡기다기관의 분기위치의 상류측에 위치하여 각 기통에 연료를 공급하는 소점식 연료 분사밸브를 설치하는 동시에 상기 연료분사밸브의 더욱 상류측의 흡기통로에 스로틀밸브를 배설하여 이루어진 연료분사장치에 있어서 상기 스로틀 밸브와 상기 연료분사밸브를 설치한 인젝션보디와의 사이의 흡기통로에, 통과하는 흡입공기를 정류하는 곡관부를 형성해서 이루어진 것을 특징으로 하는 소점식 연료 분사장치.
  2. 제1항에 있어서, 상기 연료분사밸브는 상기 흡기통로의 중심에 매달려지지 되어 있는 것을 특징으로 하는 소점식 연료 분사장치.
  3. 제1항 또는 제2항에 있어서, 상기 곡관부는 상기 스로틀밸브를 지지하는 흡기조정밸브와 일체로 형성되어 있는 것을 특징으로 하는 소점식 연료 분사장치.
  4. 제3항에 있어서, 상기 곡관부는 상기 스로틀밸브의 하류의 흡기통로의 유선을 90°방향 전환시키는 것을 특징으로 하는 소점식 연료 분사장치.
  5. 제4항에 있어서, 상기 곡관부의 굴곡부 내측에 위치하는 내벽부와 그 외측에 위치하는 내벽부가 상기 스로틀 밸브의 최상류측에 위치하는 부위와 그 최하류측에 위치하는 부위가 서로 대응하는 위치에 형성되어 있는 것을 특징으로 하는 소점식 연료 분사장치.
  6. 제1항에 있어서, 상기 스로틀밸브의 하류가 2개의 배럴로 분할되어 있으며, 각 배럴내에 각각 연료 분사밸브가 배설되어 있는 것을 특징으로 하는 소점식 연료 분사장치.
  7. 제6항에 있어서, 상기 곡관부의 출구부가 상기 2개의 배럴을 덮도록 좌우로 넓어지는 스커어트부를 갖는 것을 특징으로 하는 소점식 연료 분사장치.
  8. 제6항 또는 제7항에 있어서, 상기 곡관부에 의해 그 유선이 90°방향을 변화하도록 구성되어 있는 것을 특징으로 하는 소점식 연료 분사장치.
