THE advantages of introducing gmphited oil above the piston of an I.C. engine have for long been appreciated. As to its effectiveness as a cure for valve trouble, resulting from the use of leaded petrol, we cannot say from personal experience. This claim. however, is made by Cylub Accessories, Ltd., 76, Horseley Field, Wolverhampton, manufacturers of the Cylub injec
tor, which is a device for introducing graphited oil direct into the induction Pipe.
This upper-cylinder lubricating unit comprises an auxiliary oil supply, the container for which is carried on the dashboard, and an injector valve which can be controlled either mechanically or manually.
A regulated supply of the lubricant flows from the container through a pipe, in which is inserted a visible gauge glass, to the injector valve which is fitted in the induction pipe.
There are two types of injector valve, the mechanically controlled one functioning through the ignition-switch mechanism, a diaphragm valve in the induction pipe, or it may be connected. to the hand-brake gear, and a manually operated device controlled by means of a pull-out knob on the instrument panel.
In the first-mentioned case lubricant is injected when the engine is. switched off, or the hand-brake applied, and in the second case it can be introduced at will or cut off altogether.
The unit is the invention of Mr. Allan Thomas, A.M.I.A.E., of Wolverhampton.
