Hs{Lord Ernest Hives - Chair}4/LG12.10.25. OBJECT OF TEST. Piston troubles on 'Phantom'. TESTER. A.C.Lovesey. CONDITIONS. Test Bench. SUMMARY OF TEST. We consider that we urgently require a modified design of piston for the Phantom. Apart from the question of knocks which is causing considerable trouble on production cars, we feel sure that if we can get a piston which will bed uniformly and fit the bore we shall reduce the oiling troubles. We notice that other makers are using very flexible designs of aluminium pistons. Hs.{Lord Ernest Hives - Chair} | ||
