Re: Petrol Tank 14.B.5. Continental Bentley V.{VIENNA} ----------------------- Herewith is PD.359 shewing the 18 gallon petrol tank for the Continental Bentley V.{VIENNA} The actual full capacity is approximately 19 1/4 gallons. We understand that Rm{William Robotham - Chief Engineer}/Dixon suggests that the thickness of the body be tried as .036" and the baffles and end plates either .022" or .024". It is proposed to try the tank at first without a stone guard, and no protection for the units on the tank face. An electrically operated reserve tap to D.CD.893 is fitted and a standard single wire gauge. A standard suction sump has been modified to accommodate 2 suction pipes, giving 2 gallons reserve. This tank is not so good as our standard type for avoiding loss of suction on gradients or camber. For that reason we have got the suction sump towards the back of the tank. On an incline of 1 in 4 and no camber, the main suction fails at 2.750 gallons when climbing which we consider quite reasonable. On a decline it fails at 2.875 gallons. The effect of camber is not very bad as the tank is short. We have indicated on the top and bottom flat faces of the tank between the baffles finger grooves to prevent drumming. If desired the tank can be tried without these but they may be necessary on the top. Cont'd...... | ||
