TourEngine · raw details

TourEngine has developed an engine that reduces fuel consumption and harmful emissions by utilizing a novel thermal management strategy. In addition to being useful for current internal combustion engines, the technology can also be integrated into hybrid engines. TourEngine has a patented opposed-cylinder split-cycle combustion engine with the potential for substantial efficiency gain as a result of its improved thermal management. It also offers significant reduction in noxious emissions. Unlike hybrid and electric engine technologies that offer improved efficiency but are expensive and complex, TourEngine is simple, as it is based solely on current cylinder/piston technology. The TourEngine splits the conventional four-stroke cycle between two opposing cylinders: a cold cylinder that hosts the intake and compression strokes, and a hot cylinder that hosts the combustion and exhaust strokes. Splitting the cycle allows flexibility in the design and thermal management, consequently leading to improved energy utilization. The direct coupling of the two cylinders, a fundamental deviation from previously proposed split-cycle designs, minimizes the potential losses from splitting the cycle.
