What Is TSCiTM Technology

TSCiTM is a revolutionary combustion system enabled by injecting supercritical fuel directly into the combustion chamber. Direct injection of fuel in the supercritical state enables significant fuel efficiency improvements to be achieved. For example, supercritical injection enables cost-effective compression ignition of gasoline in engines with a conventional architecture. This is described as “Injection Ignition”, and it results in efficiencies that are equal to or better than today’s Diesel engines. TSCi™ also enables new combustion strategies to help OEM’s achieve future reductions in emissions levels. So far, a number of top automotive and engine manufacturers have engaged Transonic and are advancing their powertrain plans to incorporate TSCiTM technology.

Why TSCiTM Technology Powertrain technologies have expanded to include not only direct propulsion, but also parallel and series hybrids, and plug-in electrics with range-extending internal combustion driven generators. Internal combustion is at the core of all of these, and will continue to be the prime powertrain technology well into the foreseeable future. From a refinery output standpoint, it is impractical to move our entire vehicle fleet to Diesel fuel. Therefore, major efficiency gains need to occur with gasoline fueled engines to meet the future’s ever more stringent fuel economy and emissions requirements. TSCiTM addresses the problem of spark ignited gasoline internal combustion being less efficient than compression ignition of Diesel.
