MOTOR INDIGESTION

Many motor engines suffer from indigestion because the food supplied to them is too rich, that is, too much petrol in proportion to air. The result u that,eventually carbon deposits form in the cylinders, with consequent overheating and poor pulling power. As a simple illustration,.take an ordinary kerosene lamp. When the wick, is lighted and turned to the best position to give a bright light, the gas issues from the glass chimney without odour or smoke. If the passages which supply the flame with air are blocked, the flame is decreased, and gases, in passing out of the chimney, form carbon deposits on the lamp glass.

So it is with a carburettor. If tho mixture delivered from the carburettor is not perfectly atomised, an engine does not give that sweetness of yinning and resultant, power obtainable with a proper mixture, but overheats and a bad smell is emitted from the exhaust. In addition to this an over-rich mixture means a gross waste of petrol,
