OBJECT OF TEST.
Radiator tests on Hispano Car.
TESTER.
A.{Mr Adams} C. Lovesey.
CONDITIONS.
Taken on road wheel dynamometer.
SUMMARY OF TEST.
These tests prove that the radiator plus fan efficiency of the 40/50 HP. is considerably higher than the Hispano when taken in still air.
The curve showing a comparison between the EAC. and 40/50 HP. indicates that we ought to have less difficulty with water boiling troubles.
Tests are now being made comparing radiator efficiency on the road.
