The Optimum Fuel Heater
This month I built and installed a new fuel heater for my Plymouth
Neon and the Hyundai Excel. I have been experimenting with a low
temperature fuel heater (1/4” copper pipe wrapped around the radiator hose) and
with a high temperature fuel heater (1/8” copper pipe wrapped around the
exhaust pipe), and with a combination of both with a mixing valve to regulate
the temperature. I have determined that the best temperature for the fuel
is the highest temperature possible without vaporization, which causes the
engine to sputter and stall. This vaporization occurs between 220 degrees
and 230 degrees on the Hyundai which is the only vehicle that I had the mixed
system installed on. I had experienced vapor problems with the Neon from
210 to 230 degrees. I have been driving the Hyundai with the mixed system
so that fuel temperature was 160 to 190 degrees and had no problems.
I wanted to design a fuel heater system that was automatic,
passive, simple and optimal. A system that uses no electrical energy and
needs no adjustment would be best. A temperature of 180-200 degrees is
desired.
