CAR ENGINE WEAR
CORROSION THE ARCH-ENE&Y Not all motorists are aware that their car engine is mostly run "at too low _ a temperature, and still fewer realise that nearly all engine .wear takes place with the water temperature below about ISSdeg F. Wear, incidentally, is uot the correct word, indicating as it does a kind of grinding by attrition. Actually corrosion is the arch-enemy, audi it takes place during the initial warm-up of the tngine, and in most cases during a lot of the ordinary running about when the power unit never gete, hot' enough to resist corrosion. What happens will interest most motor _ owners, says the ' Dunlop 'Bulletin.' The products of hydrocarbon combustion are water and carbon j dioxide. Individually, they are non-corrosive, but together they make carbonic acid, which is corrosive. Above 185 deg F., the products of combustion are separated and harmless; below that temperature, they combine to from carbonic acid. Hence the desirability of warming up the engine ,a« quickly as possible.
