The tinkering began in garages in San Diego and Israel
The goal? Make one of civilization’s most valued workhorses – the internal combustion engine – vastly more efficient.
Company co-founders Dr. Oded Tour and his father Hugo Tour, former head of the IAF’s (Israeli Air Force’s) Mechanical Labs, had a keen insight about internal combustion engines (ICEs): knowing that ICEs lose about a third of their energy to cooling, and another third to exhaust, the father and son duo decided to “split” the conventional engine cycle into two distinct “hot and cold” halves. In true entrepreneurial fashion, their first effort essentially “siamesed together” two lawnmower engines. One half handled the cold process (intake and compression) while the other half handled the hot process (combustion and exhaust). And so, Tour Engine’s split-cycle was born
More advanced prototypes and state-of-the-art computer simulations were developed in the months and years that followed. Outside, independent experts predicted that Tour‘s patented engine design – with its focus on “thermal optimization” – could be 30% more efficient than today’s best ICEs.
Up to 30% More Efficient in Simulations
Tour Engine is a thriving technology company
We are diligently focused on perfecting and commercializing an efficient, simple, and green internal combustion engine for the growing distributed generation energy markets.
Tour’s business opportunity – and potential impact on society – is enormous.
The IC engine global market is made up of multiple verticals that are expected to have a CAGR of over 5%, with an estimated yearly market of over $370 billion by 2030. With time, some verticals will plateau and decline (ex. private transportation) while other verticals are expected to substantially grow, such as engines for distributed generation. Future engines running on carbon-neutral fuels will enable essential resiliency for the growing distributed generation energy markets.
