Air pollu)on caused by Shipping in Europe
SOx 2.3 million tonnes a year!
NOx 3.3 million tonnes a year!
PM emission 0.25 million tonnes a year!
By 2020 these emissions are expected to grow by 40 – 50%!

with BOS Emulsified Fuel System
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!

Water cools the combustion temperatures lowering NOx emission. The system can reduce NOx up to 20% meeting TIER II!
LESS NOx!SMALLER SCR!

Complement !SCR (Selective Catalytic Reduction)!
Reduce initial CAPEX (capital expenses)!
Lower recurring OPEX (operational expenses) !
As BOS EFS reduces NOx up to 20% at source, the size of SCR can therefore be reduced!

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.!
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!
SECONDARY ATOMIZATION OPTIMUM 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 eect.
IMPROVED COMBUSTION
Secondary atomization eect causes finer fuel mist and better fuel-air mixture for combustion

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