The Vaporizing Of Paraffin for High-Speed Motors
(Electric Ignition Type)

106 VAPORIZING OF PARAFFIN. which. is a good feature; indeed, it is claimed for this system that it is the only one in which a stop of an hour can be made without having to restart on petrol; in point of faet, there appears to be no clifficulty at all in restarting on paraffin after a stop exceeding half an hour,. which is an important consideration, as for many pur- poses, such as motor cabs, shopping and town calls, this means, of course, a material saving in petrol; it also simplifies manipulation. Many of the conditions pointed out above are complied with in the Contanesco carburettor vaporizer, shown in Figs. 80 to 83, inasmueh as the vaporizing capacity is large, and the amount of atomizing air is limited to within 1.0 to 15 per cent, of- the total volume supplied when running full out. A peculiarity in this, better known as the G. C. paraffin vaporizer, is that it takes the form and funetion of a muffler, somewhat after the manner of the Bassford, but differs from this in having* separate diluent and mixture throttles t. t1. Another feature in the G. C. consists in its location under the frame of the car ; indeed. on account of its size, it would be difficult to otherwise place it. The exhaust from all the cylinders of the motor passes through it, and first enters by the pipe x to a thick star section cast-iron radiator x1, enclosed in a thin wrought-iron pipe. Paraffin fed from a float cistern / enters along a perforated pipe F, laid along between one pair of ailettes over the exhaust radiator x1; between another pair of ailettes is laid a second pipe a1 for the supply of atomizing air from a, supplied in volume varying direetly as the fuel feed. Both pipes are perforated for about one-half their lengthy and the vapour and air are drawn along the spaces
