Endorsement in English
In may 2004, management of the Vehicle
Maintenance Department of the City of Utrecht's Public
Transportation Corporation were very enthusiastically
presented with an opportunity to save fuel, reduce
emissions and extend periodic filter change intervals.
In summary a proposal that would be beneficial for
our bottom line (fuel savings), the environment (particulate
and gaseous emissions) and filter maintenance intervals.
We would realize all of this by simply installing
a technical "aid", called an Algae-X 500, in the fuel
line of our company buses.
Suspicious as most engineers would
be, and having been confronted with all kinds of "technical
wizardry"in the past, we needed to first get clear
answers to our questions from Mr. Hans Tieland, the
Algae-X company representative and even that left
us with several more or less relevant and unanswered
questions. Never the less, we decided to take a closer
look at this opportunity and equip five two-car Volvo
buses. (B10MTHD 102 KB) In cooperation with Mr. Tieland
we very closely monitored the performance of these
To prevent triggering any changes
in driving behavior, we did not inform our drivers
that this equipment had been installed. After the
evaluation period it appeared that we had realized
a fuel savings of 7.3%. Even then we had our doubts
about the functioning of this equipment and asked
for backup and explanation by someone from the factory
in America , who was flown in to in more detail explain
the technology incorporated in the "device".
Still not entirely convinced, our
company decided to do another evaluation with a much
larger number of buses. We made installations in 10
Volvo double-car buses (engine type TDH 102 KB), 10
Van Hool standard buses with DAF engines (engine type
PE 270) en 10 Van Hool triple-car DAF powered buses
(engine type PE300). We very thoroughly monitored
these 30 vehicles and their measured performance.
After the Algae-X installation and evaluation period
on these thirty buses, we had again realized a fuel
savings of 7.13%.
It was not because of our "sentiments"
or the "technical explanation", but simply the registration
"hard (data) facts" that has lead to our company's
decision to directly this year (2005) install Algae-X
on all our fleet buses equipped with diesel engines.
The realized savings will pay back the investment
within half a year.
