Show Low Grade Automobile Fuel Causes Priming Probably no other problem of operation oper-ation for the motorist is so universal in its application, affecting alike the lordly twelve and the humble llivvur, as that of securing ease of starting. There is a basic reason for this condition con-dition and it is found in the grade of gasoline that is now produced. The fact that our oil refiners now include in "gasoline" heavier components compo-nents than in the old days renders the motor fuel hard to vaporize and needing need-ing heat for ellicient action. This is why cold weather makes it hard to start the cold motor. There is not a section of the country, even the sunny Southland, where the colder months do not bring difficulties in starting. Unquestionably the best way of securing se-curing easy starting is by priming with some fuel lighter, more volatile and more easily fired than the ordinary ordi-nary gasoline that serves very well after the engine has been warmed up. An equipment for this purpose is easily installed on any car. It consists con-sists usually of a small air-tight tank holding about a quart of the priming fluid and this is generally located under un-der fhe hood. A pipe leads from this tank to the inlet manifolds and another an-other pipe to a pump or other control on the dash. By operating the control con-trol a small quantity of the lighter fuel from the auxiliary tank is ln- Jecied into the inlet manifold, is sucked out of the combustion chambers cham-bers and fires at the first spark. A number of different fluids are used for priming. What is known as 70 degrees gasoline is entirely satisfactory. satis-factory. This is simply a gasoline of the sort that we used to get years ago, before demand caught up with supply and passed it, forcing the oil refiners to lower the grade of the fuel. This high-test gasoline may he procured from any of the big oil companies or from drug shops of the better sort. Within the last year or two some of the oil companies have been producing what is known as petroleum ether. This is simply a lighter product from the crude base, differing little from high-test gasoline. It makes an admirable ad-mirable priming compound and with a tank of this on hand an easy start may be secured even in the coldest weather, 20 or 30 degrees below zero. |
