Transonic Combustion uses supercritical-state fuel to radically shift the technological benefits of the automotive internal combustion engine This technology was featured at the ARPA-E Innovation summit and has DOE funding.
TSCi Fuel Injection achieves lean combustion and super efficiency by running gasoline, diesel, and advanced bio-renewable fuels on modern diesel engine architectures. Supercritical fluids have unusual physical properties that Transonic is harnessing for internal combustion engine efficiency. Supercritical fuel injection facilitates short ignition delay and fast combustion, precisely controls the combustion that minimizes crevice burn and partial combustion near the cylinder walls, and prevents droplet diffusion burn. Our engine control software facilitates extremely fast combustion, enabled by advanced microprocessing technology. Our injection system can also be supplemented by advanced thermal management, exhaust gas recovery, electronic valves, and advanced combustion chamber geometries.
Fuel efficiency improvements enabled by advanced combustion technologies of 50% or more for automotive engines (relative to spark-ignition engines dominating the road today in the U.S.) and 25% or more for heavy-duty truck engines (relative to today’s diesel truck engines) are possible in the next 10 to 15 years
Our fuel system efficiently supports engine operation over the full range of conditions – from stoichiometric air-to-fuel ratios at full power to lean 80:1 air-to-fuel ratios at cruise, with engine-out NOx at just 50% of comparable standard engines. Our real-time programmable control of combustion heat release results in dramatically increased efficiency.
Along with operating on gasoline, our technology can efficiently utilize fuels based on their chemical heat capacity independent of octane or cetane ratings. Thus, economical, highly functional mixtures of renewable plant products can be utilized which are not practical in either conventional spark or compression ignition engines. In dynamometer testing on current engine architectures, our technology has successfully run on gasoline, diesel, biodiesel, heptane, ethanol, and vegetable oil. Recently our engineers achieved seamless operation alternating between several different fuels on one of our customer’s engines in our Camarillo test facilities.
