Do Atkinson Cycle Engines Last Longer?

Do Atkinson Cycle Engines Last Longer? While a modified Otto-cycle piston engine using the Atkinson cycle provides good fuel efficiency, it is at the expense of a lower power-per-displacement as compared to a traditional four-stroke engine. How much more efficient is an Atkinson engine? The end result is a maximum thermal efficiency of 37 percent
