Abstract :
IC engines lose 42% of their energy to exhaust. So a number of methods to increase the performance of the internal combustion automobile engines have been established. A better method of utilizing the exhaust is being achieved by this paper. The method uses the exhaust gases from an optimal sized engine currently used. This pressure and temperature is being used and sent through a nozzle or set of nozzles which reduces the pressure to about 1.3 bars and generates high velocity gases at exit. This high velocity gas is being utilized to drive a turbo generator (turbine coupled with a generator) which powers the auxiliary units such as the car batteries head lights etc. so fuel economy is greatly saved which is the need of the hour. This paper thus incorporates the use of axial flow impulse turbine which is better than radial flow proven by current researches. The power obtained is better than conventional systems using the exhaust gases. The aim thus ascertains that power is given to all auxiliary systems such as the air conditioners, head lights, can be used to charge the batteries of the car implying that fuel economy is increased.
