阿特金森循环

阿特金森循环(英语:Atkinson cycle)是一种由英国工程师詹姆士·阿特金森英语James Atkinson (inventor)James Atkinson)于1882年发明的内燃机形式。

阿特金森循环发动机提高了效率,但降低了功率密度,其缺点是在低转速时效率低、扭力较差。阿特金森循环最初用在某些混合动力车辆上,近期某些搭配可变汽门正时车辆可切换奥图循环及阿特金森循环以追求更高的燃油效率[1]

阿特金森循环

理想的阿特金森循环包括以下几部分:

  • 1-2 等熵或是可逆绝热压缩
  • 2-3 等容加热(Qp)
  • 3-4 等压加热(Qp')
  • 4-5 等熵膨胀
  • 5-6 等容冷却(Qo)
  • 6-1 等压冷却(Qo')
