The Stazione Sperimentale per i Combustibili, a fuel combustion and analysis laboratory, reports directly to the Italian Ministry of Industry. Accredited by Accredia _ and financed by major fuel importing companies (gas, petrole, coal), the SSC has checked emissions and specific fuel consumption on a Diesel vehicle running with XBEE Enzyme Fuel Treatment.
The selected vehicle was a Fiat Marea 1.9 JTD SW, Euro 3 standard and equipped with a Common Rail. The laboratory applied NEDC driving cycle procedures (European directive 98/69/CE) and ECE 15 sampling (directive 91/441/CEE). The driving cycle was subdivided into two phases: an urban phase (UDC) and an extra-urban phase (EUDC).
UDC Urban Driving Cycle | EUDC Extra-Urban Driving Cycle | NEDC (UDC + EUDC) New European Driving Cycle |
|
|---|---|---|---|
| CO - Carbon Monoxide (%) | -4.6 | -5.9 | -4.8 |
| HC – Unburned Hydrocarbons (%) | -2.6 | -5.5 | -3.3 |
| CO2 - Carbon Dioxide (%) | -2.4 | -2.3 | -2.4 |
| NOx - Nitrogen Dioxide (%) | -0.8 | 14.1 | 6.9 |
| PM – Particles (%) | 12.7 | -13.3 | -2.4 |
| Consumption (%) | -2.4 | -2.3 | -2.4 |
Each experiment was conducted three times under strictly identical conditions in order to ensure the results were repeatable.
These results express the variations between EN 590 standard diesel and the same improved with XBEE natural fuel additive.
These experiments have demonstrated the XBEE fuel cleaner’s ability to reduce natural fuel over consumption in recent vehicles which engines are slightly clogged up. This phenomenon is also amplified by the enzyme catalysis in normally (or very) clogged engines, which may lead to decreased fuel consumption in the order of 3% to 10%.
