My invention Arelates to internal combustion en
gines, and more particularly to means for supply
ing and vaporizing liquid fuel thereto and the ig
nition of the atomized fuel.

One object of my invention is to provide an>
improved form of vaporizer and ignition device
for internal combustion' engines, which can read
ily be applied to various standard types of gaso
line or oil burning engines.
