The Vaporizing Of Paraffin for High-Speed Motors
(Electric Ignition Type)

PETROL C AR BUR ETTORS. 11 devised by the writer for supplying accurately propor- tioned mixture to a single-cylinder petrol engine under direct control of a throttle; this method is obviously limited in its application to comparatively slow-running engines, and. even at its best, a very slight tightening down of the piunger giand p materially affects the degree of deflection of the vane v, and although since applied in a more direct acting manner to an auto- mobile motor, a pulsator carburettor depending on the action of velocity of mixture flow in combination with a spring return movement cannot be considered a success. The difficulties of applying an injection pump to produce a constant mixture of var ving volume will be better realized when it is clearly understood that the liquid
