ASIMPLE fitment has been designed by. Mr. T. A. Wright, of 62, St. George's Park Avenue, Westcliff-onSea, with the object of increasing the temperature of mixture passing through the induction pipe of a model A Ford This, of course, permits the employment of a low-grade, cheap petrol with a consequent saving in fuel costs, or improves the vaporization in cases where cheap fuel is already in employment; this results in more economical running.
The theory underlying the idea is based upon the fact that the mixture divides into two streams when it reaches the curved portion of the pipe_joining the two inlet ports ; where it divides into two streams it tends to miss the hotspot in the inlet pipe.
Mr. Wright's device consists of an aluminium casting which, being connected to the exhaust manifold, conducts heat to a large area of the inlet pipe around which it passes. In this manner the effect of the hot-spot is much increased and it is difficult for the mixture not to come into contact with the heated metal, thus avoiding a vapour containing beads of liquid petrol.
The vaporizer is known as the Loirite. In the accompanying illustration it is shown in position on a Ford engine. It is held by two bolts; the work of fixing takes but a few moments.
A point in connection with easy starting after short stops is that the Loirite retains a good deal of heat by reason of the thickness of the metal ; this affects the warmth of the gas remaining in the inlet pipe and aids a rapid start after a short period of inactivity.
The inventor's claims include reduced consumption, better acceleration, smoother pulling on top gear and freedom from spluttering when. starting from cold, due to the heating up of the ingoing gas.
An example of the Loirite has been installed for several
weeks on a Ford vehicle under our observation. On 10 gallons of spirit, priced at 1s. per gallon, the car covered 237 miles, 82 miles of which were in traffic, the average consumption being a gallon for 23.7 miles. On three gallons of spirit, costing is. 1d. per gallon, it covered 79 miles, or at the rate of 26.3 m.p.g.; 21 miles out of the 79 miles were in traffic. In the latter test it was found possible to use a compensator jet one size smaller than previously. The results show a saving of between 5 per cent. and 10 per cent. The inventor recommends the use of only cheap fuel with the device. We understand that the device will be sold at a popular price.
