AIM
`
To optimize the NOx emission in diesel
engine using EGR.
INTRODUCTION

Biodiesel is an alternative fuel .

Biodiesel can be used directly as fuel for a diesel engine
without any modification of existing engine.

It has the major advantages of having high biodegradability,
excellent lubricity and no sulfur content.

Environmental compatibility compared to conventional fuels.
NEED OF DIESEL ENGINE

Diesel engine is used as Prime movers in transport,
Agricultural Sector and Power Generation. Because of
higher thermal efficiency and lower specific fuel
consumption.

But it pollutes the environment by its Combustion
Products.

They contain Nitrogen Oxides, Carbon
Hydrocarbon and Particulate Matter.
Monoxide,
Reason for choosing alternate fuel

After the oil price rise in 1973, and with global pollution due to
energy conversion processes, following important aspects
have emerged.

Increasing cost of energy sources is affecting individual, social
and national life and economy.

Depleting energy reserves of fossil fuel (coal, petroleum,
products, oil, gas) has produced energy crisis.

Increasing energy consumption rate and depleting supplies all
over the world is resulting in continuing inflation and energy
shortage. This is called energy crisis.

Large fossil fuel burnt engines without emission control
devices are emitting NOX, SOX, CO etc., in atmosphere
resulting in pollution, ecological disasters , global warming,
acid rain etc., energy, environment are closely inter-linked.
OBJECTIVES

The objective of this study is to investigate the combustion and
emission characteristics of dual fuel combustion.

Blending fuel used in the current work has been selected on
the basis of some chemical and thermodynamic properties.

To study the engine performance using fuel blends.

So the objective of the project is to reduce the NOx emission in
DI engine by using the ether as a blend and in dual fuel mode.

BLENDING

Biodiesel engines are prone to cold-starting problems in winter
seasons and emit more nitrogen oxides.

To overcome these problems, diethyl ether is used as a fuel
additive for biodiesel.

The lower percentage addition of diethyl ether with biodiesel
improves the engine performance and emission characteristics.

The experimental results support that diethyl ether can be
used as an additive with biodiesel to improve the performance
and emission characteristics.
