Many ideas have been tested
recently and sometimes more than one at a time. This has at times caused a decrease in mileage from what we
are used to. The intake vaporizer,
especially with the intake air heater seems to have been a rabbit trail. Since we installed the intake air heater
we have consistently achieved disappointing results. About the same time the heater was removed we
discovered a fuel leak in the fuel heater caused by the fuel line off the fuel
heater rubbing against a bolt and wearing a hole in it. There had been a fuel smell under the
hood for a few weeks so this fuel leak may have caused the disappointing
results attributed to the air heater.
Electronic
Control Advances
Since
the last newsletter we have designed a new electronic control circuit (#3) and
improved on the shortcomings of our previous new circuit (#2). What was discovered is that when we
adjusted the fuel ratio with the #2 circuit a change was being made to the
ignition timing advance map as well.
This gave us a typically too advanced timing for the conditions of the
engine. We have since recovered
some of the timing change but may still be able to do more to optimize the fuel
ratio and the ignition timing advance.
In
the mean time we discovered a few things about the operation of the ECU and
took advantage of the new information with a third alternative to electronic
circuits. Our third circuit is as
easy to build as the second and once used it can be shut off until the vehicle
battery is disconnected or when the "check engine" light needs to be
reset for an emissions inspection.
Addendums and changes to our manual have been made to include all the
newest discoveries.
Hydrogen
Power Boost
A
local horsepower enthusiast who is brother to my daughter's best friend
expressed some interest in Hydrogen Boost as a horsepower booster for his hot
rod. After Pete signed a licensing
agreement we had a consultation for four hours and discussed the changes needed
to produce an extreme horsepower booster for any engine. The goal was to design a system that
could achieve a short term horsepower boost (say 25 to 50 horsepower for 5 to
15 seconds) without the damaging affects of a NOS (nitrous oxide) system. Of course any system that would give a
boost of that much power would likely have some potentially damaging affect on
the engine.
The
present Hydrogen Boost system has already been proven to boost the maximum
horsepower available with the Hyundai Excel by up to 4.7% (see August 29, 2001
Newsletter report). We have
confidence that the Hydrogen Boost system can be modified to produce the
desired power boost, described as similar to a NOS system. This system will have to break some of
our usual rules (like never accumulate the explosive gases) but the concept is
viable and it would have a ready market if proven safe. NOS system owners are weary of having
to purchase that expensive bottle of nitrous oxide, which the Hydrogen Boost
system would eliminate. Our system
would manufacture the explosive gases on board during normal driving conditions
and accumulate them for injection during the power boosting operation.

you are interested in an alternative horsepower booster to the NOS system,
please contact us about your interest.
