| (15) Heat to Oil & Water. These will give an indication as to whether the engine is likely to behave normally under high temperature conditions on the road. (16) Specific Petrol Consumption. This should be obtained to give a measure of the distribution efficiency on the car. (17) Oil & Water Pump Delivery. It should be ascertained that the water pump delivery is satisfactory for idling conditions, and that the oil pump will give a reasonable oil pressure at low speeds when the oil is at its maximum temperature, say 120°C. inlet, and the bearings worn. (18) General Corrosion. Observations should be made to see whether the water passages in the head and block tend to choke up. In the case of an engine which has an aluminium head and a cast-iron block, particular attention should be paid to this point, as some protection against oxidation of the block will be required. (19) Camshaft suitability for slow running. It is difficult to predict the slow running likely to be obtained by any camshaft unless it is tried with its own manifold. A true opinion on idling can never be obtained on the test bed. 100 hours on the test bed. 10,000 miles on the Continent. 5,000 miles in England, particularly in London traffic. | ||
