LESS PM EMISSION !
cleaner exhaust!
Better combustion and presence of steam reduces and
softens the soot, resulting in cleaner exhaust and
reduced PM emission.!
The smoke will be visibly cleaner!
There is increasing drive in the industry to get rid of
this polluting and harmful PM for the human health!

A commonly known solution to improve the fuel atomization is to increase the fuel
pressure which requires upgrading the engineering design of the fuel pumps, high
pressure fuel injection lines and the fuel injectors. These all come with high
additional costs. !
BOS Emulsified Fuel System offers a cost
effective way to improve engine efficiency
by improving the fuel atomization during
fuel injection without having to modify the
engine.!

13. with
BOS
Emulsified
Fuel
System
Smaller fuel droplets will achieve better fuel-air mixture
as more fuel-air surface will be available for
combustion!
The secondary atomization effect of water particles in
fuel creates even smaller fuel droplets after injection!
FUEL SAVINGS OF 2-5%!
Less carbon footprint!
Better combustion efficiency!

14. SECONDARY ATOMIZATIONOPTIMUM EMULSION
For best fuel savings the
optimum water content is 10%
and particle sizes of 2-8 micron
When the water-in-fuel emulsion is
injected into the combustion chamber,
the water particles flash o immediately
causing a secondary atomization eect.
IMPROVED COMBUSTION
Secondary atomization eect
causes finer fuel mist and better
fuel-air mixture for combustion

Better combustion and presence of steam reduces and
softens the soot which also improves the condition of
the engine.!
