Exhaust Emission Control - Image of a typical SCR system
Many engine manufacturers have already met the new
USA, Euro and Japanese environmental control leglislations - others are nearly
there - The following is a diagram of how Cummins has designed their system and
what is does. The basic principles are the same for other manufacturers, but their
working modules are probably different. Still others are solving the emission control
regulations in different ways.
SCR - Selective Catalytic Reduction technology.
SCR is the name of a post-combustion technology treatment for diesel vehicles,
that allows them to reduce emissions of PM particulate matter
and NOx (nitrogen oxides).
DEF Diesel Exhaust Fluid
There are various manufacturers of SCR technologies who employ a DEF
as part of their system.
Azimut 77 wins award for best exterior design This Azimut beauty powered by tripple Volvo Penta 1200 IPS engines
The Azimut 77 is powered by triple Volvo Penta 1200 IPS engines
each producing 900 hp, 662 kW.
This Italian sports beauty goes at 36 knots - that's 67 km/h -
and my heart gets feelings of awe and admiration when I look at her!
Congratulations to Azimut!
Her interior is not too shabby either - expand the image below to
check it out.
For more details go to Azimut's website or visit this month's
Cannes boat show on the web - sorry the actual show's over - last day
was the 15th September.
Biogas is gas produced from organic materials like plant waste, animal excrement etc.
I intend to build a biogas plant on my farm - can I use biogas to run my diesel engines?
In its usual form you cannot use low pressure biogas to power diesel engines.
There are experiments going on to do this, but to date the results have not been good.
In America and Europe biogas is getting converted to RNG (Renewable Natural Gas) on a very large scale.
RNG and LNG (Liquefied Natural Gas) can both be used to run diesel engines.
Some garages in Sweden and Germany only sell RNG while others only sell LNG.
In short, you cannot use biogas to run your diesel engines, but you can use RNG if you can produce it from your biogas.
If you run on gas here, probably it'll be LNG from Sasol,
but there's no reason it can't also be RNG from your farms.
Specialised biogas engines are however manufactured and work with spark ignition systems.
For example Scania has a 9 liter biogas engine.

World Shipping Fair in Hamburg - Sept. 09 - 12, 2014
The biennial Ship Building, Machinery and Marine Technology International Trade Fair will be held in Hamburg, Germany.
We hope to bring you more news about it but especially of the diesel engines
to be exhibited at the fair, and of the engines to be used in the boats on display.
