In March 2005, the Italian company Fleet Consult asked the SSC to develop a program to monitor diesel vehicle emissions and fuel consumption. The said vehicle was a light car, a Fiat Marea 1.9 JTD SW Euro 3, equipped with a common rail. It drove 6,500 km using XBEE Diesel.
The program analyzed the following parameters:
· Regulated polluting emissions: CO, HC, NOx;
· Particles and CO2; and
· Diesel consumption.
Measures have been performed in compliance with a regulatory test under the New European Driving Cycle (NEDC, directive 98/69CE) implementing sampling procedure ECE 15 as specified in directive 91/441/CEE. The cycle itself is subdivided into two cycles, the Urban Driving Cycle (UDC) and the Extra-urban Driving Cycle (EUDC).
| Gas Emissions | Regular Diesel | XBEE Diesel | Difference % |
|---|---|---|---|
| CO (g/km) | 1.74 | 1.66 | -4.6% |
| CO2 (g/km) | 200 | 195 | -2.4% |
| Consumption | |||
| Calculated | 7.7 | 7.5 | -2.4% |
