THE SUPER CHARGER GLANCE AT ITS FUTURE

Supier-oharging gives remarkable results in increased power output, it has not been adopted very much for the ordinary touring car, but has been used rather for speed purposes and to (rive a higher power output toi a given displacement. In this it has been successful. . Ll • But its advantages lie in the opposite direction, states a writer in the “Field.” It .seems obvious that it super-charging can gi ve increased power and speed from a normal-sized engine it can be used to give noi ami power and speed from an engine considerably below the normal. Applied to small displacement engines it would have the effect of reducing size and weight and tax and yet giving us the power we need. It would mean a good performance with more room for body and passengers and with reduced wear and tear of tyres and transmission mechanism, tars could be considerably lighter for the same speed and power capacity This is surely a step in the right direction, and it is confidently to be expected that shortly this aspect of the super-charger question will mak.9 itself felt in the counsels of tin* automobile enineers. If super-chargers are to be , largely adopted it will be on small cars, not on large ones. They are eminently suited for the requirements ol' the As mall car maker and user, and when the latter begins to visualise what the device may mean it is probable that a demand will arise which could not be resisted by the makers and designers. j The super-charger gets over the one weak point in internal combustion engine design. That is the use of piston suction to draw in the charge. This means a reduced charge as the speed increases. The super-charger eliminates this fault and therefore is a scientific and the natural method of introducing the fuel.
