The Internally Radiating Impulse Structure (IRIS) is an advanced internal combustion engine design with thermal, volumetric and cycling efficiencies superior to those currently available or under development in ICEs. Break thermal efficiency of a standard automotive ICE is about 25% – meaning engines waste 75% of the fuel they consume in the form of heat. The IRIS is a transformational geometry for the ICE combustion chamber that increases the area of the chamber reacting productively to expanding gases and provides superior mechanical advantage to economically increase efficiency to over 45%. The IRIS will also substantially reduce engine weight, size and CO2 emissions and improve performance.
The design has already received major awards for innovation in efficiency from Dow Chemical, ConocoPhillips and NASA. It has also attracted advisors including Eric Ridenour, the former COO of Daimler-Chrysler, Rob Lachenauer, former head of Boston Consulting Group’s automotive practice, and renowned energy expert Daniel Yergin.
For over 100 years, engine efficiency has improved incrementally. The IRIS promises a breakthrough. That’s why NASA Tech Briefs called the IRIS engine a “rapidly deployable solution to some of the toughest problems facing the world today.”
