Atkinson valve
WebAn Atkinson cycle engine is of increasing popularity in hybrid powertrains, with a main aim of adjusting valve timing. Being similar to an Otto cycle, the Atkinson also leaves the intake valve open for a short time during compression stroke. Decreasing compression ratio to around 8:1 and lowers the pressure on the piston on the power stroke.
