| General summary of the above tests show 1. That the water temperature is unaffected by various means of body ventilation (dashboard not being filled in and side engine guards being louvred during all the tests) Generally this is the worst condition for heating up the water, tests at high speeds did not cause so great a rise in temperature. [Handwritten Note]: I think Wolseley Ford means running at 25 m.p.h. full load with trailing wind is worst condition. 2. The temperature inside the body is reduced considerably and brought to quite normal conditions by causing pressure inside the body by the front windows being open, the floorboard temperature only slightly decreased but not materially, this is more noticeable when the side windows are also closed with the front windows left open. These features also exist under other conditions such as engine running light load or car running at high speeds. 3. The dashboard ventilators do not materially affect the general condition but those under the floorboards do slightly lower the floorboards and inside temperature whereas those above the floorboards also slightly lower the temperature inside but only when the car is running at high speeds. As regards the conditions inside the body, as above described the smell referred to is that of hot lubricating oil. There is evidently also some passage of air from the back of the undershield into the body as one can distinctly smell the burnt oil of the foot brake [Footer Text]: SC/EC 320V (100 M.{Mr Moon / Mr Moore}) (X GLO 897/15) (C) 4000 | ||
