Show COAL GAS USED TO DRIVE jp CARS New Auto Fuel Is Being Experimented Vith in British Isles. First-class petrol, or gasoline, being no longer obtainable in England and Scotland, the ingenuity of man lias devised de-vised a plan to utilize coal gas as a substitute. In a recent article on the gasoline situation sit-uation in England the Motor Age says: London has been experimenting witli coal gas as fuel for some time. It is found that a gallon of gasoline can be replaced by cubic feet of coal gas. The cars using coal gas substitute gas bags for the steel cylinders, the steel naturally being needed for war purposes. pur-poses. In Scotland the gas is carried in a rubber-canvas bag on top of the car. There it costs 71 cents a UO0 eubic feet and gives a saving of about oO per cent in fuel. The price varies in London. Lon-don. In the north, near the coal fields, it is sometimes as low as 24 cents a 000 cubic feet, increasing in other places to as much as 7'2 cents. Even at the latter figure, however, the actual . cost of the gas used works out equivalent equiva-lent to 24 emits a gallon, or in tlie case of cheaper gas, to S cents a gallon. Where the jjas is used tlie connection I with the engine is made through the induction in-duction pipe just above the throttle valve. Absolute combustion of the gas has not been attained, hut it is believed it soon will be with experiment. The only difference detected in the running of the engine is that gas gives slightly less power. A big development i" tlie use of coal as is expected as soon as normal times return, particularly in the omni bus field. One oni nibus company now makes a double journey of fit teen miles on one filling of the holders, which have a capacity of about Sbu cubic, feet. Managers of corporation gas works are preparing for expansion of sales of tlie gas. The ma rkel may even become be-come permanent in character if inventors invent-ors can provide rh:id cylinders of a size and lightness suitable for commercial motors. Jt is thought that if satisfactory satisfac-tory cylinders can be fashioned the fuel may compel e successful )y even in normal times with petrol or gasoline. |
