Automobile Emission is one
of the major problems in environment.
Engine emits the carbon monoxide (CO),
hydrocarbon (HC), Nitrogen oxides (NOx)
and smoke density etc. NOx emission leads
to dangerous effect in the environment. NOx
can travel long distances, causing a variety
of health and environmental problems in
locations far from their emissions source.
These problems include ground level ozone
and smog, which are created in the
atmosphere by the reaction of nitrogen
oxides and hydrocarbons in the presence of
sunlight. Various methods are used to
reduce the Nox emission. In the present
work Exhaust gas recirculation (EGR)
technique is used the diesel engine with
biodiesel as fuel. Papaya fruit seed oil is
used to prepare the biodiesel in this present
work. Experiments are conducted in a
singlecylinder, four-stroke, water-cooled,
directinjection diesel engine coupled to an
Eddy current Dynamometer with EGR. The
result shows that NOx emission is reduced
using EGR for diesel and bio diesel.
