Abstract

Traditional turbocharging systems make use of the energy carried by exhaust gases by placing a turbine-compressor arrangement in the exhaust line of the automobile. The major problem with this system is the high back-pressure developed in the engine cylinders due to the obstruction provided to the exhaust flow by the turbine blades. The back-pressure results in higher operating temperatures, higher fuel consumption and overall lower engine performance The proposed system replaces the turbine-compressor arrangement from the exhaust line and places a heat exchanger which extracts heat from the exhaust and transfers this heat to pressurized air on the other side of the heat exchanger; it is this hot pressurized air that is used to drive the turbine-compressor arrangement. Since, the arrangement does not impede the flow of the exhaust it is expected that the back pressure will decrease resulting in the overall improvement of engine efficiency.
