A Review - Performance Evaluation of Single Cylinder Four-Stroke S. I. Engine Using Turbocharging System

Abstract

Now a day's whole world facing the problem of reducing the fuel. So there is need to reduce fuel consumption. In a conventional IC engine a considerable heat is carried away by exhaust gases. To recover the waste heat, various methods are being adopted. One of them is turbo charging. In this project an attempt has been made to explore the various possibilities of waste heat energy recovery methods in conventional commercial two wheeler and four wheelers. In this context, a new concept of hybrid engine has also been discussed. The heat Energy carry in the exhaust gases are recovered in different methodologies. Firstly, by introducing an auxiliary combustion chamber and injecting an additional suitable fuel and then allowing it to expand in a turbine which forms the part of turbo charger unit.
The waste heat energy is used to burn an additional amount of fuel. The second stage contains a thermoelectric generator which produces electrical energy by utilizing the high heat of exhaust gases. The third stage energy recovery is done by coupling a compressor and an alternator. Both being coupled to the turbine shaft, produces electrical energy and compressed air which can be accumulated and used effectively for running any auto auxiliaries. Thus the principle of electro turbo generation has been adopted for waste heat recovery In order to use the aforesaid combination of waste energy recovery systems a matrix has also been suggested.
