1 Preface
According to telephone order through Mr. Thies Algner on 13-jul-2006 comparative fuel consumption measurements should be accompanied at vehicles with a fuel-saving module on test stands and documented. The measurements were scheduled for 18-jul-2006.
By means of test stand cycles it should be ascertained how the mileage of a vehicle changes in comparison to the serial state if the vehicle related to a defined fuel amount with the module Fuel-Tec XP1. More information for the signer there were not at the moment of the order.
Basis for the creation of the survey were the measurements carried out on 18-jul-2006 at the test stands of the Bosch Service Center at Hamburg-Rahlstedt as well as the photographs produced on this occasion.

The above mentioned vehicle is supposed to have corresponding to the serial state. Vehicle documents were not available. References to the technical changes to the vehicle did not turn out.
2.3 Place of the measurement / measurement technology
The measurements were carried out in the Bosh Service Center of Johann Muller GmbH & CO. KG, Neuer Holtigbaum 5, D-22143 Hamburg, Germany.
The measurements were carried out on an achievement test stand for the manufacturer Bosh, type FLA 203, device-Nr. 010 051 0 of 22nd checking-documents the gauging accuracy of the used Bosh test stand and/or the Messtoleranzen of the single measurements parameters show, the signer could not be presented to.
By means of test stand the speed and the covered distance of the vehicle were measured continuously and indicated above screen.
2.4 Test condition / result of measurement
The test method, as well as the place of the measurements with corresponding measurement technology named in the previous section was set by the customer.
Checking-documents for the test stand could not be presented to the signer. During both test runs no impedance was steered on the roles of the test stand.
The test vehicle was supplied through the customer. An investigator of the vehicle with regard to technical changes was not carried out by the signer. References to technical changes to the vehicle did appear.
During test runs all secondary consumers of the test vehicle were off. The heat dissipation during the measurements was guaranteed through a blower put forward the vehicle.
The fuel, Super unleaded under DIN EN 228, was acquired in the presence of the signer at an ARAL service station in amounts of each 10 liters and filled in new and empty barrels.
To derive as by means of the previously mentioned limiting conditions, it is not a question of any standardized, certified or reproducible methods of measurement.
The first measurement was carried out with the module Fuel-Tec XP1.
Before the first test run the vehicle on the test stand was heated to operating temperature and was run for so long until the vehicle stopped the motion independently due to a lack of fuel.
The fuel tank of the vehicle was completely filled with a previously measured amount of 10 liters via the tank inlets.
The integrated distance counter showed a performance of 21,148 km before the first measurement. The trip mileage recorder was put on 0. The distance measurement should occur in parallel via the test stand.
The vehicle was started immediately after the filling with fuel and accelerated in the automatic gear D up to a speed of approximately 90 k.p.h. Consequently this speed was retained by means of speed rule installation continuously.
Under the previously mentioned limiting conditions the vehicle was practiced on the test stand until the engine stopped the motion independently for lack of fuel. During the first measurement an outside temperature of 30.5 degrees of centigrades could be read on the integrated instrument.
On the distance counter of the vehicle a total performance of 21,301 km and at the tip mileage recorder a distance of 153.2 km could be read.
The distances shown via the test stand and the integrated were documented by means of photographs.
The distance of 156.151 km read at the test stand should form the basis of 100% for the measurement immediately subsequently carried out with the module Fuel-Tec XP1.
Immediately on completion of the first measurement and documentation of the measured values b y means of photographs the test module Fuel-Tec XP1, model 610 was attached to the underside of the fuel tank of the test vehicle.
The vehicle was filled renewedly with a measured fuel amount of 10 liters. Provided under the given circumstances, the vehicle was accelerated under the known limiting conditions as with the first measurements of approximately 90 k.p.h. and consequently practiced by means of speed controller with a speed of approximately 90 k.p.h during the second measurement an outside temperature of 32 degrees of centigrades could be read on the vehicle instrument. Also this second measurement with the motion independently due to a lack of fuel.
The vehicle was started immediately after the filling with fuel and accelerator in the automatic gear D up to a speed of approximately 90 k.p.h. Consequently this speed was retained by means of speed rule installation continuously.
Under the previously mentioned limiting conditions the vehicle was practiced on the test stand until the engine stopped the motion independently for lack of fuel. During the first measurement an outside temperature of 30.5 degrees centigrades could be read on the integrated instrument.
After the vehicle stopped the motion independently for lack of fuel, a distance of 156.151 km could be read on the monitor of the test stand.
On the distance counter of the vehicle a total performance of 21,301 km and at the trip mileage recorder a distance of 153.2 km could be read.
The distance shown via the test stand and the integrated instrument were documented by means of photographs.
The distance 156.151 km read at the test stand should form the basis of 100% for the measurement immediately subsequently carried out with module Fuel-Tec XP1.
Immediately on completion of the first measurement and documentation of the measures values by means of photographs the test module Fuel-Tec XP1, model 610, was attached to the underside of the fuel tank of test vehicle.
The vehicle was filled renewedly with a measures fuel amount of 10 liters. Provided under the given circumstances, the vehicle was accelerated under the known limiting conditions as with the first measurement of approximately 90 k.p.h. During the second measurement an outside temperature of 32 degrees of centigrades could be read on the vehicle instrument. Also this second measurement with the module Fuel-Tec XP1 was carried out until the engine of the test vehicle stopped the motion independently due to a lack of fuel.
According to test stand, during the measurement with the measurement with the module Fuel-Tec XP1 a distance of 192.945 km could be covered to the independent adjustment of the vehicle motion. Furthermore, a miles performance of 21,490 km could be read on the integrated distance counter and/or on the trip mileage stance of 189 km. The distances displayed on the test stand and the vehicle instrument was documented as well by means of photographs.
Related to the distances determining at the test stand an additional distance of 36,794 km was covered during the second measurement with the Fuel-Tec XP1-Modules. This corresponds under the mentioned limiting conditions to an increase of the covered distance of 23.56%.
The result of the singular, not standardized comparison measurements is based exclusively on the values read off and does not consider any measured value tolerances, surrounding and envoi mental influences as well as any circumstances of the accompanied measurements not influence able or controllable through he signer. Thus a guarantee for the determined result of measurement cannot be given under the mentioned limiting conditions on the part of the signer.
3 Summary
According to instructions comparative measurements were performed on a test stand by the signer. The distances were measured that were covered by the test vehicle with same fuel amount with ought and with the module Fuel-Tec XP1 of the company Nature Bio Systems LLC (USA).
The measurements were carried out according to the client's instructions. The displayed result is based exclusively on the juxtaposition of two distance measurements and considers no measuring tolerance, technical as well as surrounding or environmental influences and neither controllable circumstance of the accompanied measurements. For the determined result of measurement the guarantee is excluded on the part of the signer.
With regard to the limiting conditions under witch the measurements were carried out and the result of measurements basses the measurements on that one the detailed carrying out must be referred to in the survey. During the comparative distance measurement with the module Fuel-Tec XP1, module 610, a 23.5 per cent higher distance could be put back by the test vehicle than with the measurement without the module Fuel-Tec XP1.
4 Epilog
This survey became impartial and created according to best known knowledge and conscience.
