PRODUCTION - DISTRIBUTOR GOVERNOR CURVE. Following the decision to standardise 6.5 : 1. compression pistons EB.4587, we have carried out tests which show that the governor curve which we have developed for use with the vernier control is equally suitable for 6.5 or 7 : 1 pistons, and should be standardised. Full particulars are given on the curve attached. Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} | ||
