I NVESTIGATIONS into the effect of adding fuel to the air intake of an oil engine have shown that any fuel, irrespective of its ignition quality, can be used successfully as the main charge. This was revealed by Mr. W. T. Lyn, M.Sc.(Eng.), in a paper which he read last Friday in London to members of the Institution of Mechanical Engineers.
Fuel introduced in the form of a spray provided a means for suppressing combustion noise and rough running. The scheme offered a way of increasing engine output for a given allowable exhaust condition, with an accompanying rise in thermal efficiency.
Much the same ground was covered in a second paper by Mr. L. D. Derry, Dr. E. M. Dodds, M.A., D.Sc., Dr. E. B. Evans, Ph.D., M.Sc., and Mr. D. Royle, B.Sc.(Eng.). Research had shown that by using 75 per cent. of the normal maximum oil-fuel input and employing gasoline aspiration up to the limit imposed by the normally accepted smoke limit, a power increase of just over 20 per cent, was obtained. Air utilization was about 80 per cent., as against about 68 per cent, for normal operation.

four-hour shifts. The proposed fare was 12 10s. which was 11 8s. 6d. below the railway rate.
Granting the application, the Yorkshire Licensing Authority imposed a fare of 12 18s. 3d„ which, having regard to the crew of each vehicle, he considered to be economic.
