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 vaporization in
the carburetor Therefore, by
pre-heating the inlet air to the carburetor for a considerable amount, the vaporization can be ease and in turn complete combustion is achieved. Moreover by reducing the water vapor 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 ex-changer inside the exhaust pipe. The atmospheric air is sucked through the
heat ex-changer to the carburetor The
air which is flowing though the heat ex-changer gets heated by the engine
exhaust gas. This reduces the water vapor 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.
