Supercritical Fuel System: 50-75% Improvement in Engine Fuel Economy

The TSCi gasoline fuel charge enters the cylinder at around 400 °C—compared to about 100 °C for a conventional liquid direct injection fuel charge—at precisely Top Dead Center (TDC, 0° crank angle).
The supercritical charge facilitates short ignition delay and fast combustion, with the energy released focused just on pushing the piston down. The fast combustion minimizes crevice burn and partial combustion near the cylinder walls, and prevents droplet diffusion burn.
