Hydrogen-Boost Test Results Detailed
See also the detailed test results in our winter 2003-2004 newsletter at http://www.hydrogen-boost.com/winter20032004.html
In the charts
below the numbers in the body of the charts represent actual tested average
fuel mileages achieved under the conditions represented at the top of the
column and with the equipment listed at the left of each row.
The column for test track is for the results obtained on 50 miles
test drives on a 8 miles loop here in town where the speed limit is 40-45 mph
and road is suburban in character. Test drives on this "test
track" included using all the driving techniques in the Hydrogen-Boost
operator's manual and newsletter updates. All vehicles were
standard shift 5 speed except the Hyundai was only a 4 speed. Some
testing was during the cold winter, some during last fall, and some this
spring. Each row of the chart indicates the results with the indicated
equipment.
The following are the meanings of the abbreviations in the first column:
H2 - Hydrogen-Boost gas generator

heat - a simple fuel pre-heater was installed
oil - Excel Plus engine treatment or synthetic oil
plugs - Platinum tip spark plus installed
