Growing demand for energy, with
consumption being met primarily
through the combustion of fossil fuels,
means atmospheric pollution, a most
serious challenge facing the world to-
day. The impact of pollution on the hu-
man body and the whole environment
– particularly in mega cities – and in
the light of the amazing rate of growth
in industrial output and mobility on
the sub-continent, reducing overall
emissions pollution is a real chal-
lenge. There are, therefore, two major
requirements affecting the design of
the combustion engines of today and
tomorrow, namely, eco-compatibility
and efficiency. As national and interna-
tional regulations governing emissions
and atmospheric pollu-
tion become even more
stringent, to the point at
which further optimisa-
tion of in-engine and on-
engine measures alone
no longer suffices, post-
combustion exhaust-gas
after-treatment systems emerge as ab-
solutely essential.
The Indian Government has intro-
duced legislation similar to that en-
acted in Europe, initially starting with
stage BS I in 2000. In April 2010, BS
IV came into force, laying down emis-
sion levels aimed at alleviating the
conflict of interests between a country
in the process of developing and the
necessity of protecting the environ-
ment. Indian emissions legislation re-
quires as of April 2010 the installation
of exhaust-gas after-treatment systems
in motor vehicles in use in the Na-
tional Capital Region (Delhi) and 12
mega cities, with the same restrictions
being applied nationwide as likely
2014/2015. This will affect all 3- and
4-wheelers as well as trucks and buses.
HJS Emission Technology special-
ises in exhaust-gas after-treatment
technologies for more than 30 years.
The systems for diesel particulate re-
duction, denox and combined systems
that reduce both soot and nitrogen ox-
ide emissions can be applied to a wide
range of light and heavy duty on- and
non-road applications. At the German
Head Office over 500 employees are
engaged in the development, produc-
tion and marketing of modular systems
for reducing pollutant emissions.
Since 2008 HJS is operational in In-
dia and has established the subsidiary
HJS Emission Technology India Pvt.
Ltd. in March 2011 as a first major step
to become part of the fast
growing Indian Automo-
tive Industry.
Since 2010 HJS is sell-
ing Partial Flow SMF
(Sintered Metal Filter)
and complete systems
to achieve BS IV legis-
lation with great success. Besides the
existing business HJS runs develop-
ment projects with all major OEMs of
vehicles and diesel engines.
A new Partial Flow Particulate Fil-
ter for the 1 & 2 cylinder diesel engine
segment will be launched beginning
of 2012. This new development will
broaden the application range for open
particulate filters from 5 kW up to 350
kW. All these Partial Flow SMF sizes
can be used uncoated or with a catalyt-
ic platinum coating. One box housing
designs which includes an upstream
Diesel Oxidation Catalyst (DOC) or
a two box housing design, where the
DOC and the Filter were canned in
separate housings, are possible.

in Delhi (NCR) start-
ing from the second
quarter of 2012.
