Abstract:
An apparatus for dithering fuel into an internal combustion engine includes a turbine that is powered by the internal combustion engine and a first fuel injector that injects a first fuel into an air stream to create a fuel/air stream. The apparatus also includes an air/fuel compressor that provides a compressed fuel/air stream to the internal combustion engine. The air/fuel compressor is powered by the turbine, and the air/fuel compressor compresses the fuel/air stream to create the compressed fuel/air stream. Additionally, the apparatus includes a second fuel injector that injects a second fuel into the compressed fuel/air stream prior to the compressed fuel/air stream entering the engine and after the compressed fuel/air stream exits the air/fuel compressor.
