Alternative fuels used in conventional engines

have a low probability of success….

Your challenge ….


Have 100 year fixed mechanical controls

Combustion is not controlled

Do not meet today’s needs

Does not make sense to try and force alternative fuels to work with outdated controls

Conventional Engine issues:


Alt Fuels Need Modern Engine Controls

Ultra fast digital valves Adaptive intelligence

Flexible combustion cycles Prevention of emissions

““Diesel Power August 2001 – Jason Thompson“ With this engine, air (instead of fuel)

manages the timing.

“At any given time the engine can be programmed to operate as a two, four, six, eight…..even up to 12 strokes.”

“The result…20% increase in thermal efficiency,more power, and the ability to adjust to changing fuel types on the fly”.

“

“Braking energy could be recovered and used to helppropel vehicles without the need for expensive batteriesOr electric wheel motors.
