Fuel Economy in a Diesel Engine
Test Report
For REWITEC GmbH, Dr.-Hans-Wilhelmi-Weg 1, D-35633 Lahnau
A passenger car with diesel engine was used for a short initial validation of the Rewitec Nanocoating technology. To determine the influence on the fuel consumption and exhaust and particle emissions of the vehicle, the following coatings were applied to the vehicle:
- Rewitec M2 Nanocoating for engines and
- Rewitec G5 Nanocoating for gears
Technical characteristics of the car:
| Manufacturer | Volkswagen | Type | Passat TDI |
| Mileage | 147,700 (1 9.12.2006) km | Displacement | 1900 cm3 |
| Power | 96 kW/4000 rpm | First registered | 25. July 2002 |
| Engine | Diesel ¨C Euro 3 |
Evaluation:
a) (NEDC warm): 2 particle and exhaust emission tests, New European Driving Cycleb) 1 fuel consumption test at 60 km/h (38 mph) constant speed, 3rd gear, average time 420 sec
c) 1 fuel consumption test at 90 km/h (56 mph) constant speed, 4th gear, average time 420 sec
d) 1 fuel consumption test at 110 km/h (69 mph) constant speed, 5th gear, average time 420 sec
The measurements were taken once before (1st) and once after (2nd) the treatment of the car with REWITEC Nanocoating. Between the two evaluations the car was driven by its owner in normal work day use for about 3,800 kilometers.
Outcome:
The results of the consumption values are represented in the following chart:
| Date | a) NEDC (warm) | b) 60 km/h | c) 90 km/h | d) 110 km/h | Mileage |
|---|---|---|---|---|---|
| Consumption | L per 100 km | L per 100 km | L per 100 km | ||
| 19.12.2006 | 6.79 | 5.93 | 6.23 | 7.10 | 147,700 km |
| 14.02.2007 | 6.08 | 5.33 | 5.88 | 6.56 | 151,300 km |
| -11% |
-11% | -6% | -8% |
There is a noticeable decrease in fuel consumption evident over the whole measurement. As a result of this, it is important to recognize the resulting decrease of CO2 and particle emissions.
