he Albion 01. is now fitting to machines so ordered :1 ne;\ type or paraffin carburetter, winch is controlled by a Murray patent governor. In this carburetter, the fuel is fed through a usual type of float chaniber to a jet, and 1:i atomized by the inrushing air. Onlv a small portion of the total velume of air passes by this jet, and the rich mixture or air and atomized paraffin is immediately condueled to a vaporizing chamber, whkh has a large corrugated heating surface, this surface being kept hot by means of the exhaust gases. The rich vaporizett gas from this eliamber is then led to a standard Albiout mixing valve, controlled by the governor, the operation of widen valve and governor is intended to insure the admission to the cylinders of the correct amount of additional air along with the rich gas front the vaporizer. The arrangement of the heater, choke tube acid float hamber is clearly shown in one of our illustrations, in which view part of the vaporizer cover has been broken away so as to show the corrugated surface of the chamber. The other view shows the general arrangement of the throttle chamber and the governor connections: those iiarts. it should be noted, are similar to those lilted on till 10 lep. Albion petrol vehicles. Hot air is led to a horizontal choke tube (Al. from above the exhaust pipes, thrhligh a bent pipe; the paraffin nozzle in eonnection with the float chamber (B) is vertical, and projects for ahont 1.in. into the choke tube at. its smallest diameter. As a result of this arrangement, hot, air passes over the jet at a very-high speed, and thus atomizes the issuing paraffin The rich mixture of paraffin and air then passes to the exhaust-heated chamber ten one side of this chamber is ribbed, as may be seen in the illustration, and these ribs break up the mixture into small streams of gas in ,'intact with the considerable heating surface. An air-tielit cover (D) is provided, end, in order to prevent loss of heat by radiation from the heater, the cover is lined with a thick sheet, of asbestos, the asbestos being protected inside by a. thin steel plate. In this heated chamber, the mixture is thoroughly taporizeci before it reaches the lagged mixture pipe (P.:). In series with this pipe, there is a hand-regulated valve (0), by which additional air may be admitted so as to dilute the rich mixture. The valve is suitably connected, by means of a short rod, to a spindle which passes through the dashboard, and to this spindle the hand-regulating lever is secured. From the valve (G), there is an extension pipe (T1). AV/lir:11 is provided so as to prevent the hissing noise which would otherwise, be (Tented by the air's rushing through the valve when the latter was only partly open. This band-regulated air valve is fitted simply for the pinpose of adjusting the mixture to suit the atmosphere eon(Akins of the day.
The arrangement of the throttle ehamber and governor connections, which is shown in the other view, as already stilted, is similar to that used in vonnection with the type of carburetter fitted to all 16 h.p. Albion vehicles since June, 1909. The rich hot mixture enters the throttle chamber (J) by an inlet flange (K), and is there diluted hy cold air which enters by way of the speed air branch (L) and a speed air valve (M); this last-named valve controls the amount of extra air whielt is given under full load at any speed of the engine. The mixtore then passes to the cylinders by way of the pipe (N).
