Improvement of Engine Performance to Reduce Fuel Consumption of a Single Cylinder Spark Ignition Engine

Fuel is the mam source of energy in the world and being used widely in
powering vehicles by internal combustion process. The used of fuel keep growing day
by day and however the source of fuel cannot be renewed. Even though scientists have
already introduced alternative renewable energy in placed of fossil fuel, the
implementation cost very high capitals investment. Thus car manufacturer are
competing to develop highly efficient vehicle that consume lesser fuel than th e
previous generation of vehicles. The project undertaken here attempts to minimize
engine fuel consumption by implementing engine optimization. These were performed
by several tuning process to improved air fuel ratio of the engine, ignition system, and
several modification to reduce the engine work load. Furthermore engine is retrofitted
with Electronic Fuel Injection (EFI) replacing the usage of carburettor. As a conclusion
all the improvement performed on the engine have increase the engine performance and
reduce the fuel consumption significantly. The engine maximum torque has increased
from 1.5 N.m to 2.1 N.m at 5000 rpm and the engine fuel consumption reduce from
reduce and produce a better mileage from 1242.8 mpg to 2662.9 mpg.
