 164 MOTOR ROAD TRANSPORT throttle, is fitted into the induction pipe immediately above the atomizer. The aim of the contrivance is, of course, to try and improve the carburation by getting a dryer and better mixed gas than would be obtained with a standard carburettor alone. A practical test of the invention was made on an “ average ” Ford car. One journey was made without the atomizer, and one journey with it. The conditions of each. run were as similar as it was possible to obtain, and the distance—from a fixed point out and back— in each case was 24 miles. Gonsumption of Fuel Results. Without Atomizer . .25-4 miles per gallon. With „ . . 42-7 „ Increase in mileage per gallon 66-77 per cent. It will be noticed that these figures are considerably in excess of those of some official tests given below. The latter taken during the war by the Royal Air Force, the War Office, and the Australian Motor Transport Service, are average figures based on observations of fleets of vehicles. The second reason for the disparity conditions throughout the writer’s test “ normal,” and consequently a good favourable to the Atomizer. is that the were more deal more Results of Comparative Tests.
