Hs{Lord Ernest Hives - Chair}5/LG26.11.23. OBJECT OF TEST. Tests on E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C-1 Engine. TESTER. A.{Mr Adams} C. Lovesey. CONDITIONS. Test bench conditions. SUMMARY OF TEST. The engine has been run under normal conditions as regards tappet clearances. The umbrella valves have stretched under this condition. When the engine is rebuilt it will have guides with extension to shroud the valve - we already have these running on a 20 HP. engine. We also have a set of valves ready for test similar in design to the 40/50 HP. Hs.{Lord Ernest Hives - Chair} | ||
