ABSTRACT An attachment for operating an internal combustion engine on either gaseous or liquid fuel incorporates a modified air cleaner assembly having spaced cover and adapter plates be- tween which is sandwiched a typical annular filter element, the adapter plate fitting over the engine air intake. An annular diaphragm connects an inner plate to the cover plate to form a chamber therewith on one side of the inner plate into which gaseous fuel is admitted. During gaseous fuel operation gas pressure in the chamber maintains the inner plate adjacent the adapter plate to form therewith and with the other side of the inner plate an annular venturi into which gaseous fuel from the chamber is admitted through a ring of ports through the inner plate at the venturi. During liquid fuel operation incoming air lowers the pressure in the chamber sufficiently so that the inner plate automatically moves away from the adapter plate to provide an unobstructed air only path to the engine air intake.
