Onboard hydrogen generation using compact plasmatron devices could provide
important new possibilities for reducing pollution from motor vehicles, mak
ing use of alternative fuels, and increasing engine efficiency. These impro
vements would involve the use of the plasmatron as a very small, rugged, ra
pid response and highly flexible means of electrical heating of gases. Plas
matron heating could be used to facilitate conversion of a wide range of hy
drocarbon fuels into hydrogen-rich gas onboard a vehicle. Use of combinatio
ns of fuels is possible through potential transformation of a variety of fu
els into hydrogen-rich gas. Another advantage of use of onboard plasmatron
generation of hydrogen is that it could be used only when required and coul
d be readily turned on and off. Preliminary experimental studies of plasmat
ron conversion of difficult-to-use alternative fuels (biofuels), iso-octane
(representative of gasoline), and diesel fuel are described. Concepts for
application to trucks and other heavy duty vehicles, sport utility vehicles
and automobiles are discussed. (C) 1999 International Association for Hydr
