Which of the following most accurately describes the problem?

We have to hand particulars of the latest Binks paraffin carburetter, which is marketed by C. Binks, Ltd., Phcenix Works, Church Street, Eccles, Manchester. The device is of that type which relies upon the heat of the exhaust gases for vaporizing the heavier grades of fuel, Like most of us who have had anything to do with paraffin carburetters, this manufacturer has long shine found that, although complete vaporization of paraffin may he effected when the vaporizer is properly heated, at times when the vehicle is being manceuvred through congested traffic and the engine has to be slowed down, vaporization becomes incomplete, the result being a smoky exhaust and impaired running. The Births Co. claims to have got over this trouble in a very satisfactory manner.

Virtually, the device consists of two carburetters in one, and, as we have said before, an exhaustheated vaporizer. The accompanying reproduction of a sectional drawing of the carburetter conveys a very good idea of its construction. There are two float chambers as well as two jets embodied ; the smaller of the jets serves as a pilot for starting up on petrol, and the larger one is brought into use when the engine is running at full power on paraffin.

A choke tube to suit each jet. is provided and in the smaller orifice, no matter bow slowly the engine may be running, there is always a satisfactory suction. The main jet is in connection with the paraffin float chamber, and is only brought into operation when the throttle of the pilot, is fully opened ; the suction through the latter being then considerably decreased, there is but a small quantity of petrol used. Each c6 jet orifice is provided with a form of damper, so that when this engine is not running, no paraffin or petrol is wasted.

Notwithstanding its duplex type of construction, there is but a single control to the Sinks. This can take the form of either a suitable hand or foot-operated lever with rods or Bowden wire. It will thus be realized that there are no auxiliary taps or levers to call for extra attention when it is required to change over fuel.

The principle of working is as follows: when the vaporizer, which the maker terms the "centrifugal" type, is sufficiently heated, the control lever is actuated to open the main throttle for the purpose of tindamping the main jet which allows for the initial atomizing of the paraffin. The spray, mixing with inrushing air and a small portion of petrol, is whirled round the

vaporize" and still further atomized before it enters the induction pipe of the engine. Upon fully opening the, throttle, by actuating the selfsame lever, the suction on the. petrol jet is decreased to the minimum.

When it is required to manoeuvre the vehicle in congested traffic, the main paraffin supply can, if necessary, be instantly cut off and, for the time being, petrol only utilized, This provision should enable the machine to be driven very satisfactorily under all close conditions.

The .apparatus appears to he quite simple to operate in practice, owing to the single-lever control.

We understand that the device can be readily fitted to most types of machines without costly constructional alterations. The manufacturer claims to effect a saving of at least 30 per cent" on the fuel bin cost.
