The advantages of the improved device reside in the fact that no pumps-are required for sprayingor pulverlzing the oil admitted to the cylinder. Oil may be fed by gravity past the inlet valve or by a slight pressure in the oil tank in a, manner well understood. A further advantage resides in thefact that the pulverization and vaporization of the liquid fuel is brought about entirely by mechanical means having no reciprocating parts, which is of especial value for engines when used for high speed (tractive) purposes. The engine may be started and operated in the manner described in Patent No. 1,121,135 issued to me-on December'15,191 t in which case the air supplied to the cylinder may be mixed with a suitable proportion of light oil such as petrol or gasolene by passing it for example through a carbu reter, but in many cases it will be found that the engine may be started directly with heavy, diflicultly inflammable fuel by-actuating the rotary device with compressed air from a storage tank or by an electric motor supplied from a storage battery, or in some other convenient way, thus permitting the pulverization of the heavy fuel at starting. 7
