X1908 AERO ENGINES - FLIGHT TESTS AT TOLLERTON ON HAWKAero EngineER HORSLEY - BUZZARDAero Engine ENGINE. Referring to HS {Lord Ernest Hives - Chair} /LOV {Mr Lovesey} 5/KT2/1031., this is excellent information. It is exactly what one would expect as the temperature gets very low, and is probably (as you say) in a few cylinders only, and those the rear ones. It is an extremely urgent problem, and one hopes that a form of induction pipe that cures it will be found. One sees that this trouble does not exist in compression ignition engines, but others may at low temperatures. Also one can imagine that the full supercharger (with its higher speed blower) might be better, and that for moderate supercharging a smaller and higher speed blower might atomize better. But we hope that the natural distribution can be improved without relying upon temperature. Others as well as ourselves have had this trouble, even at ground temperatures. I suggest that at the Works we test with less and less volatile petrol. R. {Sir Henry Royce} | ||
