smaller diameter than the tube 32 to provide an
annular space 345 for the accommodation of four
vertical bolts 3t for clamping the tank- It and

My invention relates to internal combustion
engines, and has among its objects and advan
tages the provision of an improved fuel system
wherein water vapors are blended with the fuel
to increase engine operating‘e?iciency, eliminate
carbon and to e?ect economy in fuel consump
tion.
