"Quality
Control ISO 9000 – 2000"
P. Appalaraju, Deputy General Manager - Ashok Leyland
With the WTO becoming more prominent after the DOHA
deliberations the competitive edge of the Indian products must be improved.
In this connection Quality Management systems and their implementation
assume very high importance. A large number of Indian companies have already
been certified for ISO 9000 – 1994 version and QS 9000 standards – 1998
version.

"Particulate
Emission Control In Di Diesel Engine With Bimetal Catalyst"
K. Balagurunathan, V. Arumugham and D. Ganesh
Thermal Science Division, Anna University, Chennai
Now a days, Diesel Engines are gaining much importance due
to its better thermal efficiency and high fuel economy. Hence it is widely
used in automobiles, industrial units and power plants . In recent years
concern over the contribution of diesel engine particulate emissions -
particulate matter (PM) and oxides of Nitrogen (NOx) to environmental
pollution has resulted in a significant increase in research and regulatory
activity in this area world
wide.

"Fuel
Spray SimuIation in a C.I. Engine "
Prof. V Ganesan, Indian Institute of Technology, Chennai
The main objective of this work is to study the fluid
mechanics aspect of fuel spray in a compression ignition engine and to
analyse the fuel injection process taking into account of evaporation and
fuel air mixing. This can provide information on precombustion fluid
dynamics aspects of sprays. It is rather difficult to conduct experiments to
study the injection process alone in an actual engine without combustion.

"Carburettors
For Two Wheelers - State Of The Art"
S. Govindarajan, Ucal Fuel Systems Ltd, Chennai
Two wheelers are characterized by simplicity in construction
and low price. In India, the two wheelers are manufactured in different
varieties such as mopeds, gearless scooterettes, geared scooters and
motorcycles. All the mopeds and most of the scooterettes are powered by two
stroke engine. All the scooters are powered by two stroke engines (with the
exception of the latest Honda Activa which is 4 stroke powered). In the
Motorcycles, both two stroke and four stroke engines are employed. The
emission regulations were enforced from 1991 and progressively
tightened.

"Ethanol
blends and flexible fuel vehicles
- A Strategy for India"
Dr. T. R Jagdeesan, Emeritus Professor, Anna University, Chennai
It has been estimated that nearly half of the current
non-renewable petroleum demand equivalent to about 20% of the world’s energy
consumption is being used by 550 million automobiles. This clearly indicates
that the vehicles form the predominant source of regulated and unregulated
pollution. It has been established beyond doubt that the tail pipe emissions
contribute significantly to climate change. The vehicle population continues
to increase exponentially and by the year 2010 about 1.1 billion cars are
expected to be in use in the world. Unregulated Carbon dioxide emissions, a
prominent green house gas, will increase by 65% over the current levels due
to large scale use of fossil fuels.

"CNG
for Vehicles-Technological and Safety Features
"
B . S. Murthy, Emeritus Professor - IIT Madras
In the interest of public health, environmentally friendly
fuel, namely the compressed natural gas(CNG) for vehicles came into the
scene at the capital city of Delhi as remedy to reduce the high level of
atmospheric pollution. After witnessing the recent chaotic situations owing
to the failure to change over from the conventional liquid fuels to CNG, it
is appropriate now to quickly review the technological and safety features,
which are necessary for smooth transition from conventional fuels to gaseous
petroleum
fuels.

"Review
of Ethanol in Compression Ignition Engine"
G Nagarajan, A N Rao, T R Jagadeesan and S Renganarayanan
Institute for Energy Studies, Anna University - Chennai
Stringent emission legislation all over the world has led to
the search for alternative fuels for I.C. Engines. The major pollutants from
a diesel engine are oxides of nitrogen (NOx), smoke and particulate matter.
Concentration is very much focussed on compression ignition engines because
they have been recognised as the most ideal power plants in transportation,
industrial and agricultural sectors, due to their high fuel efficiency. But
their major disadvantage is the production of exhaust particulates which
have to face increasingly stringent
regulation.
