"SPEED IMPERATIVE."

Lecturing recently on the evolution of the motor, says the "Motor Cycle," Dr. A. M. Low said that the advent of the nev/ road and other conditions had made speed imperative; he believed that speeds would increase as life became more strenuous, and streamlining would be essential when average speeds of 60 and 70 m.p.h. became normal.

The improvement in materials—still continuing in the case of steel alloys and steel aluminium ' compounds—had rendered a high rate of r.p.m. safe, and in consequence threat difficulty waif experienced in getting kn effective weight of mixture into the cylinder in the short time available. To increase the "inserting pressure" by the so-call-ed forced induction engine, or supercharger, seemed an evident advance which he thought in ten years' time would be as essential as the front wheel brake is to-day. Released from the need for freak valve timings and early openin with rapid operation, the designer could' use the forced fuel system to enable him to produce more lasting valves and more silent, valve gearing. The supercharger was a phase leadins to the fuel injection engine, in which pure air'only would be compressed. so that eventually fuel would Jjo fed while flame propagation iva s actually taking place. Such a motor, he said, would help to solve the problem of using heavy fuels, and might, therefore, )>. o? value in the building of .safetyfirst aeioplanes.
