| -2- Hs {Lord Ernest Hives - Chair} /TGV.1/ML.17.8.38.Cont'd. {John DeLooze - Company Secretary} It should be added that local inertia torques in 8 cyl. engines are high as in the 6 cyl. engine, but 8 cyl. crankshafts are always stiffer than 6 cyl. ones for the same torsional period, due to being longer. This may be a cause of their greater overran smoothness, since local distortion will be less. Hs {Lord Ernest Hives - Chair} /L.Grylls. Print attached. | ||
