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

42 VAPORIZING OF PARAFFIN. with the varying depression produced in the mixing chamber, corresponding to the opening of the piston throttle h and the volume of mixture admitted to the motor. The exact degree of carburetion can be adjusted for all speeds by a movement of the slide r, by which means the width of the orifice for the admission of air can be varied to the required extent. Obviously, the number of jets brought into play, as well as the capacity of the air nozzle, could be controlled by a single move- ment of the throttle, thereby insuring a certainty of action under all working conditions ; but could only Figs. 34 and 35.—-Multiple-jet Carburettor with Variable Air and Eucl Control. be done at some sacrifice of constancy in the carburetion, owing to the reason that the velocity of mixture-flow to the motor does not necessarily correspond to the extent of throttle opening, but is influenced in part by varying speeds at which the motor is running. and while going at its slowest by the pulsating effect of each piston, o wing to varying stroke velocity.
