| -3- PACKARD. Stiffness of the frame has been measured with and without the body. A complete analysis of the rear axle, including weight particulars, has been made for B.III. Front suspension being used for reference by the Design Dept. OLDSMOBILE. Frame stiffness has been determined. Design Department has supplied all information relating to the split propeller shaft. Tests carried out on the road for front end movement and steering characteristics. When our new Test House is completed, it is proposed to run the Oldsmobile engine on the Bench and analyse the power of the side valve engine, also the H.P. loss to the exhaust system. VAUXHALL. Measurements with and without crankshaft damper to determine whether we can use such a scheme on Bentley III. This car has to be stripped for examination and complete weight analysis. WORK CARRIED OUT ON TEST BEDS. WRAITH. Problems so far encountered on the engine are:- (a) Noisy valve gears. (b) Excessive wear on the tappets. (c) Noisy timing gears. A complete report on the work so far done is to be circulated. P.III. Tests to find the best bearing metal for the big ends continue. Also checks on power losses to simplify the exhaust systems. Work on top over-oiling, and valve gear with silent tappets eliminated continues. Excessive Timing Gear Wear Investigations. An analysis of crankshaft torsional periods. | ||
