Editing Miller cycle (section)

==Atkinson-cycle engine==
A similar delayed valve-closing method is used in some modern versions of [[Atkinson cycle]] engines, but without the supercharging.  These engines are generally found on [[hybrid electric]] vehicles, where efficiency is the goal, and the power lost compared to the Miller cycle is made up through the use of electric motors.<ref name="Extended Expansion Concept">{{cite book|last1=Bernard S|first1=Stephen|title=SAE Technical Paper Series |chapter=Investigation on Performance, Combustion and Emission Characteristics of a Turbocharged Low Heat Rejection DI Diesel Engine with Extended Expansion Concept|year=2009 |volume=1 |chapter-url=http://papers.sae.org/2009-28-0006/|publisher=Society of Automotive Engineers|doi=10.4271/2009-28-0006 |accessdate=13 December 2009|ref=10.4271/2009-28-0006}}</ref>
