VAPORISATION AND EFFICIENCY.
Petrol leaves the carburettor as a spray of liquid. In the intake manifold it vaporises and becomes mixed with air. When vaporisation does not take place rapidly enough, or when too much petrol is sprayed into the manifold. the liquid will accumulate on the sides and run back into the carburettor. To get best results the intake manifold should be protected from the cooling effect of the fan, and should be warmed by a by-pass conveyor of heat from the exhaust. When the petrol in liquid form runs down into the air inlet of the carburettor the mixture will be irregular and uncertain.
In Adelaide the tax on horse-drawn vehicles produced £7000; it is said that if such a tax were applied in Londonit would undoubtedly hasten the disappearance of horse traffic, and so relieve congestion.
