WATER IN ENGINE SUMP.
Two things may cause the trouble; one of chemical origin, the other illfitting piston rings. When petrol is burned with the proper amount of air, the hydrogen and carbon of the petrol combine with the oxygen of the air to form water and carbon dioxide. Hence, water is always one of the products of combustion, and exists in the cylinder in the form of superheated steam. 111-fitting piston rings and scored cylinders allow gas to blow by, consequently more water will condense in such engines. The carburettor adjustment is also important. A mixture containing much petrol means an excessive amount of water, just as surely as it means a formation of carbon in the cylinder.
A Copenhagen man has invented a motor-car horn which emits a prolonged scream when anyone tries to steal it—otherwise, when it is pinched.
