&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The &amp;#039;&amp;#039;&amp;#039;LiquidPiston&amp;#039;&amp;#039;&amp;#039; engine is a [[rotary engine]], which operates on the High Efficiency Hybrid Cycle.&amp;lt;ref&amp;gt;Shkolnik N., Shkolnik A. “High Efficiency Hybrid Cycle Engine”, Proceedings of the ASME Internal Combustion Engine Division 2006 Spring Technical Conference.&amp;lt;/ref&amp;gt; This cycle consists of compressing air (with no fuel) to a very high ratio, as is typical in the [[Diesel cycle]]. The air is then isolated in a constant volume chamber. Fuel is injected, and allowed to combust fully under constant volume conditions, which is how [[Otto cycle]] combustion is modeled. Finally, the combustion products are expanded to atmospheric pressure, utilizing [[Atkinson cycle]].&lt;br /&gt;
