The NEVIS(New Exhaust Valve & Intake System) engine is an innovative Internal Combustion Engine (ICE) that within a single patented engine design is estimated to nearly double the fuel efficiency attained by conventional ICE technologies.


Its modular cylinder construction (e.g. 2, 4, 6 or 8 cylinder engines from a one-cylinder block) offers opportunities to enhance manufacturing efficiency while allowing a single facility to produce a wide range of engine sizes for varying power needs suited for diverse applications (automotive, aeronautic and marine). Its versatile design means it can be configured to be fuelled not only by gasoline but also by diesel, hydrogen and bio-fuels.
