We guarantee 5% fuel savings.

Reduction in Fuel Consumption is Proportional to Reduction of Particulate Matter in Exhaust

Stochiometric Combustion Conditions2,000 Mg./Cu.M. Particulate EmissionsEquivalent to 11.3% of Fuel


Results

• Combustion is complete.• Less unburned carbon material in exhaust.• More energy from fuel.• Better fuel economy.• More Power.• Less Carbon in Reciprocating Engine Oil.


Environmental Effects

• Diesel Engine Fuel Savings – 5 – 15% Range• Particulate Emissions reduced by 90%• 75% NOx Reduction


Improves Combustion Efficiency

• Cleaner Burning Fuel• Tolerates Higher Wax and Asphaltenic Content• Reduces Emissions – Particulate Matter, Unburned

Hydrocarbons, CO, NOx - through more efficient use of oxygen in combustion and less time at maximum combustion temperature.


Metallic Combustion Catalysts

Metal catalysts contribute some particulate emissions from the oxides of the metals in the engine exhausts. The level of these emissions is well below government standards for emissions.

Iron and magnesium oxides are nontoxic and benign to life forms.Iron and magnesium oxides are very high melting species and do not harm

engines through deposits or abrasion.Catalyst adds 17 ppm solids to fuel. ASTM D-975 specification limit is 100

ppm solids.


Catalyst Contribution to Diesel Engine Emissions

• 0.0064 mg/kW hr contribution by Fe2O3 + MgO at 10 ppm Fe and 2 ppm Mg

• Euro III - 0.10 mg/kW Hr < 3,000 rpm • 0.13 mg/kW Hr > 3,000 rpm

• Transportation Research Laboratories, Ltd. (U.K.) confirmed this measurement.


Engine Maintenance

• Minimize Deposits and Wear on Piston Crown and Valve Seats

• Less Carbon - Longer Oil Life
