TourEngine™ is a patented opposed-cylinder split-cycle combustion engine with the potential for substantial efficiency gain as a result of its superior thermal management. It also offers significant reduction in noxious emissions. Notably, compared to 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 4-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.
Overall, TourEngine™ presents a cost-effective alternative with a substantial increase in engine efficiency and an opportunity to revolutionize the way combustion engines are built.
