NEW BRITISH ENGINE.

ADVANTAGES OF BOTH STEAM AND PETROL. A "7 British engine,. called the Still, stated to have the power elasticity of the steam engine with all the advantages of the internal combustion engine and a higher fuel economy, was the subject of a paper by Captain F. E. D. Acland on A new prime mover of high efficiency of Arts' 0311 or ' gin " at thG E ° yal Society

Searching test of it had been made by various Governments and scientists, said Captain Acland, and it was proved to use 25 per cent, less fuel per horse-power than any other engine yet constructed, the system had already been applied in practice to engines of small and large power using gas, petrol, or heavy oil. lyes were constructed giving iip to 500 h.p per cylinder during the war period; but up to now publication had ™ w ' c '' / or obvious reasons. The Still engine Was based on an extremely simple principle. The fuel was burnt within the main cylinder. The heat lost in this process generated steam, which performed the return stroke by being expanded in the same cylinder on the other side of the piston. In this way the losses in both the combustion and steam strokes were reduced. Both weight and space were diminished, and there seemed every reason to expect that the engine would shortly be applied for marine work, gas engines, and locomotives here and abroad. If it proved successful it would amount to nothing Icbs than a revolution. Sir Charles A. Parsons, K.C.8., who presided, said Mr. Still, a member of the association, had succeeded in securing a reserve of power which rendered the internal combustion engine -much more suitable for use in ships,
