January 2006 Austria Tests (excerpts from January 2006
With the diesel
Fiesta we also did two acceleration tests. To prevent any inconsistency in clutch techniques from a
standing start, we used a flying start method. On the first test we started the
watch as I floored the accelerator with the transmission in second gear
at 2000 RPM and stopped the watch when we reached 4000 RPM in 3rd
gear (signaled to the watch keeper by my shifting into fourth
gear). The second acceleration
test procedure was to start in 4th gear at 2000 RPM and stop
at 3500 RPM, without changing gears.
the results of the tests:
Acceleration tests for the diesel Fiesta showed 9.3% faster for
Acceleration tests for the diesel Fiesta showed 10.6% faster
for test two.
Note that these
tests included an increase in tire pressure so we cannot claim a 10%
increase in power because there was also a corresponding reduction in
Today I did over 25 test runs of 0-60 mph acceleration with
various combinations of devices installed and operating on the Hyundai Excel.
Each combination of devices was tested four times on a section of road
in rural New York, two times in each direction. The slowest time
in each direction was discarded and the two remaining times (fastest
time for each direction) were averaged. The chart below shows the
average 0-60 mph time for the indicated combination of devices.
Cold fuel no devices 19.35
Hot fuel no devices
all other tests were done with hot fuel (160-195 degrees Fahrenheit)
with hydrogen 18.55
with mist 19.45
with mist and EFIE
with hydrogen & mist 19.45
with hydrogen, EFIE 19.75
with hydrogen, mist and EFIE 20.8
in table form for easier comparison the data looks like this:
w/Hydrogen w/EFIE & Hydrogen
19.35 18.9 18.55
with mist 19.45 19.45
Comparing these numbers by dividing the stock acceleration time by each
of the test times give us a rough estimation of the increase or
decrease in available long term maximum horsepower with each set of
devices operation. The following is a
Heated fuel when
compare to cold fuel achieved an increase in power of 2.6%
Hydrogen injection with heated fuel achieved an increase in power of
Hydrogen and mist with heated fuel encountered a decrease in power of
Heated fuel with mist alone encountered a decrease in power of 0.5%
Heated fuel with mist, Hydrogen, and EFIE encountered a decrease of
Heated fuel with mist and EFIE and without hydrogen encountered a
decrease of 11.4%.
Generally heating the fuel increased the horsepower.
Generally adding hydrogen increased the horsepower.
Generally adding the mist increased instantaneous available hp but
decreased long term available horsepower.
Use of the EFIE device always decreases available horsepower compared
to the same setup without the EFIE device.
EFIE stands for Electronic Fuel Injection Enhancer offered by Eagle
