| contd :- -3- MANIFOLD. USUAL POSITION To HOT SPOT The next curves give the rate of heating with the super-heat system; the standard exhaust curve being inserted for comparison. The heating rate is increased by employing the small (.025) diameter feed hole but even then approximately 2 1/4 mins. elapse before there is any appreciable rise in temperature whereas the standard system responds practically immediately. After about 4 1/2 mins. running, the temperature reached is the same as that of the exhaust contd :- SUPERHEAT SYSTEM. TEMP. °C TIME - MINS. STD EXH SYSTEM. .062 DIA FEED HOLE. .025 DIA FEED HOLE.
