EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD

EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD

SYNOPSIS

            The concept of increasing the fuel efficiency of a petrol engine in this project, is to pre-heat the intake air which is flowing through the carburetor.  The humidity in the atmospheric air affects the petrol vapourisation in the carburettor.  Therefore, by pre-heating the inlet air to the carburettor for a considerable amount, the vapourisation can be ease and in turn complete combustion is achieved.  Moreover by reducing the water vapour to the engine, the steam formation in the engine can be reduced pitting of the engine cylinder, piston and exhaust pipe.

            The pre-heating of inlet air to the engine can be achieved by fixing a heat exchanger inside the exhaust pipe.  The atmospheric air is sucked through the heat exchanger to the carburettor.  The air which is flowing though the heat exchanger gets heated by the engine exhaust gas.  This reduces the water vapour in the inlet air and the temperature of the air is raised.  The temperature raise causes complete combustion in the engine and it is also more suitable for warming up the engine in cold conditions.
