| To Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} from G.W.H. 4057 Hotel de France, Chateauroux, FRANCE. 11.11.32. 2.PER.II. Re. H1's PATENT FOR ADDING ANILINE TO THE LUBRICATING OIL. with reference to BY's memo, BY.10/G,15.10.32. This is divided into two paragraphs - (a) To give an improvement in regard to running. (b) Reduce the quantity of carbon deposited. With regard to (a) there is definitely no improvement in the smoothness of the running of the engine with or freedom, with aniline added to the oil. The result of (b) can only be obtained after a considerable amount of running. _____ we are today running our usual day's mileage in order to verify our results obtained with the softer rubbers in the engine mounting. We have also been verifying the loss of water after reducing the outlet of the water pump to 3/8". During the mrning's run we have lost 5 pints as against 1 gallon previously. we have therefore made an improvement. we shall try further reducing the outlet to see whether further improvement can be made. The engine still remains very stiff. it is also noted, which we should like verifying, that the rolling of the chassis is very poor, and seems as if there is a lot of internal friction either in the gearbox or rear axle. we have noticed this when trying to start the engine on a slight incline by pushing the car before engaging, and it appears to be very hard to get the car moving. The following has also been noted during the morning's run. CARBURATION. the carburation has several weak spots up to 50 m.p.h. this causes continual luffing up. The average consumption is still poor working out at 11.4 m.p.g. | ||
