A SURPRISE ENGINE
Few motor scientists are more : widely known than Professor A. M. Low, of London, and no scientist more regularly surprises the motor world by unique designs for cars and engines. His latest surprise is a valveless and crankless engine designed to operate at 15,000 r.p.m. Tq permit such speeds valves must be eliminated, and in their place Professor Low proposes to use a perforated cylinder head. He has found in 10 years of special tests that a combustible gas can be fed into a tube so fast that, if ignited, the flame will not be able to travel backward toward the source of gas supply. Secondly, he has found that if the gas from this tube be led into a cylinder through small, cooled perforation^ and ignited, th'e flame will not pasd back through the orifices, and very little explosive force will be lost. These principles ari eombined in his new engine, together with a system of regular pulsations of gas supply pressure. The two-stroke cycle is used, and to reduce cost of production eccentrics on the crankshaft replace cranks. Exhaust is by open ports in the cylinder walls, these being uncovered by the pistons on their downward travel.
