When there is a lubrication failure in a petrol or diesel engine it is most important that the engine is stopped as quickly as possible. Often the driver will be unaware of an oil failure; he will not notice the oil-pressure-warning light come on or a gauge showing a too-low pressure reading. In these circumstances, a safety device now being marketed by P. and J. Gehler will prove its worth.
The device is called the S and S Enginemaster and automatically shuts off the fuel supply when the lubricating-oil supply fails. It is fitted into the fuel line close to the engine and consists essen
tially of a spring-loaded valve that is held off its seat Ito let fuel flow) by a pressure-sensitive diaphragm activated by the engine's lubricating-oil pressure.
By-Passing the device is not necessary when starting the engine, nor is a special starting procedure needed when the Enginemaster is fitted. Under normal operating conditions, fuel flows through the unit but if oil pressure falls below danger level for any reason—lack of oil, faulty fuel pump, choked filter and so on—the valve closes. stopping the fuel supply and the
engine stops before serious damage can be caused.
A further feature claimed for the Enginemaster is that it will prevent air-locking of the fuel system when a road vehicle or item of plant equipment with a low fuel level in the tank is on a severe gradient. It is also said that a system having the Enginemaster fitted will not need bleed
ing atter running out of fuel.
No electrical contacts or power are required with the device and it is designed to fit most makes of engine from 3 to 1,000 h.p. Tests in various parts of the world are reported to have shown reliability of the device in any climate with complete freedom from mainten
ance. The S and S Enginemaster "fails safe".
