The Atkinson-cycle engine is a type of internal combustion engine invented by James Atkinson in 1882, designed to trade power density for greater efficiency. Modern variations of the cycle appear in hybrid and non-hybrid vehicles that use variable valve timing, letting the same engine run in Atkinson cycle mode for fuel economy or switch to conventional Otto cycle mode for greater power output.
