NOVELTY - The apparatus, in form of a heated catalyzed fuel injector (30), has an input fuel metering system dispensing a fuel charge into a pressurizing chamber preferably during the power stroke of the engine, a pressurization ram for compressing the fuel charge within the pressurizing chamber, and an injector nozzle for injecting the fuel charge into the engine combustion chamber (28). The fuel charge is heated in the pressurization chamber in presence of a catalyst.    USE - Apparatus for dispensing fuel into combustion chamber of internal combustion engine. Uses include but are not limited to high octane rated fuels, high cetane rated fuels, mixtures of gas engine fuels and diesel engine fuels, gasoline, diesel fuel, and various mixtures of cetane, heptane, ethanol, plant oil, bio-diesel, alcohol and plant extracts (all claimed) suited for engines including gasoline and diesel car engines as well as race car engines.    ADVANTAGE - The apparatus dispenses the fuel predominately or exclusively during the power stroke of the engine and lightly oxidizes the fuel in super-critical vapor phase via externally applied heat, enabling the apparatus to operate on wide range of liquid fuels. The apparatus also operates independent of spark ignition or compression ignition, as the apparatus fires at room pressure up to practical limit of the engines. Dispensing the remaining incoming fuel over a wider geometric volume within the combustion chamber facilitates a slower continuous burn due to greatly reduced fuel-to-air ratio and yields a much higher rate of combustion compared to existing lean burn. Detonation-induced fuel dispersal may be greatly enhanced by incorporating high swirl combustion geometry. When equipped on a small automotive diesel engine, the apparatus converts the same engine into a gasoline engine and enables the engine to operate at high compression ratios.
