Further investigation should be carried out by means of say, an oscillograph, to determine what difference there is between the spark characteristic of the two governors. Graph C.74 shows the required governor characteristics to suit the proposed production Bentley V engine. Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} | ||
