| - 30 - be selected and a second car attached to the one to be tested by means of a tow rope. If this car is then towed in top or 3rd gear at a fixed speed it will give hill climbing conditions. Care should be taken that the engine temperature of the towed car is constant for all tests, otherwise the work to be done by the towing car will vary with the mechanical efficiency of the engine. (ii) Scientific investigations. To compare satisfactorily the relative efficiency of the cooling systems of different makes of car on the road is a very laborious and awkward proceeding. It is sufficient to observe that it can be done, but the means employed are so involved as to be outside the scope of these notes. Tests conscientiously carried out on the lines previously outlined, should give sufficient information for all ordinary purposes. Hs{Lord Ernest Hives - Chair}/W.A. Robotham. | ||
