Efficient
When compared to common engines, TourEngine™ significantly reduces the fuel consumption by introducing a superior thermal management strategy.
Simple
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.
Green
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

Technology

The TourEngine™ design splits the conventional 4-stroke cycle of a common engine between two opposing cylinders: The Cold-Cylinder hosts the intake and compression and the Hot-Cylinder hosts the combustion and exhaust.

The first prototype was operational in 2008. This prototype smooth and dynamic operation demonstrates the feasibility of the TourEngine™ cycle. Our second prototype become operational in 2012 and proven to be a useful platform for testing various crossover valves technologies. Read More
