When compared to common engines, TourEngine™ significantly reduces the fuel consumption by introducing a superior thermal management strategy.
Simplicity is a key for success. The TourEngine™ design is based on standard cylinder/piston technology allowing manufacturers to easily adopt the technology, avoiding major overhauls.
TourEngine™ substantially reduces harmful emissions compared to common engines. It can also be easily integrated with future hybrid engines further improving their efficiency and environment-friendly attributes.
Superior Thermal Management
The TourEngine™ design splits the conventional 4-stroke cycle of a common internal combustion engine between two opposing cold and hot cylinders.

A Leap Improvement in Efficiency


The Tour engine design splits the conventional 4-stroke cycle between two cylinders: The Cold-Cylinder hosts the intake and compression and the Hot-Cylinder hosts the combustion and exhaust. A proprietary
crossover valve is used to transfer the compressed charge from the Cold-Cylinder to the Hot-Cylinder.

Our latest (2015) crossover valve mechanism is a technology enabler. It permits an efficient and complete transfer of working fluid and it is further developed both in Israel and the US. Read More
