For the second year in a row, Dr. Oded Tour, CEO of Tour Engine presented during poster presentations at the Directions in Energy-Efficiency and Emissions Research (DEER) Conference in Detroit, and garnered a healthy interest, including a visitor from Volvo.

For the Poster Presentation Session - Part 1 of the 2011 DEER Conference in Detroit, 19 presenters were given a 3-5 minute summary before the conference attendees. Those interested in following up were then given an invitation to the adjacent ball room where major suppliers had displays, large and small, of their engine-related technologies. Number 19 of the poster presentations was Dr. Oded Tour of Tour engine.

The title of Dr. Oded Tour’s presentation per the DEER agenda was: Splitting the Cycle the Right Way: An Inherently Ultra-efficient, Low Emissions IC Engine.

For more than a decade, the DEER Conference has been the U.S. Department of Energy's (DOE's) primary mechanism for the public exchange of state-of-the-art advanced combustion engine research and development (R&D); and Tour Engine was there with good reason, because every gallon saved in fuel consumption is a green event.

That is where I came in as correspondent for Torque News, because I was also a guest of Dr. Tour. Having been a design engineer in the auto industry and now as writer covering automotive technologies, I certainly took the opportunity primarily to meet Dr. Tour face to face. For the record, he had already given me a private, one-one-one phone/web presentation a few weeks ago.

It was the same presentation that often goes to venture capitalists, explaining in great detail the design and efficiencies of the Tour engine that bears the name of his father, Hugo Tour of Israel. The poster was a summary of that presentation.

This is not the first time I have reported on the Tour Engine. Read Tour Engine Inc. chosen to display at ARPA-E Innovation Summit 2011

For the record, Dr, Tour is by no means shy in his presentation nor in his beliefs about the benefits of splitting the 4-cycle engine into a cold and hot side.

First, Tour Engine is both a company and a split cycle-cycle engine design that tales the IC engine to what I believe is the next step in its evolution. It literally separates the cold side, (intake-compression) from the hot side (power-exhaust). Furthermore, it has a unique arrangement as being the only split-cycle with opposed pistons; and there is a rational reason as to why - maximum thermal efficiency.

When I finished my own 3-hour review of Tour’s design, it became clear to me that Tour intends to become the most thermally-efficient, internal-combustion engine on the planet; my words, not his.

Fact is, today’s 4-cycle engines waste energy to a great degree, they resist green, and they have become extremely complex. As such, the Tour engine addresses the three with similar terms: efficient, green and simple.

In the words of Dr. Tour, “existing four-stroke engine designs are in conflict with optimization.”

One look at the poster at DEER coupled with Dr. Tour’s explanations and you tend to realize the auto industry is expending great amounts of time and money just to achieve incremental gains of 0.5% here, 1% at best there. Thus the industry has avoided doing what’s necessary, reconfiguring the IC engine so that those gains can be made much larger and achieved in one fell swoop.
