FUEL CONSUMPTION AND EMISSION TESTING

HEAVY MINING EQUIPMENT

What is Centron?

• Liquid catalyst

• Propietary blend of Bio-

Degradeable and

Environmentally friendly

Petrochemical products

• Contains NO Alcohols

• Contains NO sulfur

How does Centron Work?

• Functions as a catalyst to

increase the amount of the

fuel molecule burned in the

combustion process

• Centron reduces the

surface tension of the

fuel, utilizing more of the

energy that would

normally be lost in the

combustion process!

How does Centron work?

• Centron interacts with fuel to create

micronized droplets that combust (burn) at

lower temperatures when injected into the

combustion chamber

• This interaction with fuel creates a more

efficient and complete fuel burn, resulting

in a reduction in fuel consumption, more

power and less Emissions

• Also, the detergent properties of Centron

provide a complete fuel system cleaning

including injectors creating optimum spray

patturn efficiency and utilization of fuel

In addition to improving Fuel Economy Centron is

Proven to Reduce Toxic Emissions by 30% - 60%

Use Centron to Join the Fight Against Greenhouse Gases

• Carbon Monoxide / CO 37% - 57%

• Carbon Dioxide / CO2 15% - 47%

• Hydrocarbons / HC 53% - 67%

• Nitrates of Oxide / NOx 40% - 43%

• Opacity (PM) 27% - 81%

Centrons Additional Benefits

� Lower maintenence costs

� Increases the useful life of vehicles and machinery

� Increased lubrication reduces engine wear

� Cleans engine and fuel injection system

� Eliminates algae growth

� Requires no special transportation

� Registered with the EPA

No loss of warranty

LA MARIA MINE - Sonora, Mexico

The tests of La Maria Mine in Sonora gave results of

29% in reduction of emissions, 45% in opacity and

13.8% to 14.6% in savings of fuel

• On the 14th to the 20th of December 2007 tests were carried out with Centron in the Mine Maria in Sonora Mexico

• Trucks tested were CAT 630E

• During the test 6.387 liters of fuel in a total of 144 working hours, were consumed

The result of the test was a reduction of 29% in emission

contaminants (CO, HC and NOX) and 45% in opacity
