| 4. (C) Brico. (D) R.R. iron. (3) Freezing and unfreezing of Bentley or 30 H.P. cylinder block with 1 1/2 water in. No.2.Bed. Single Cylinder Unit. Effect on power by reducing exhaust duration and in effect a later exhaust opening. Comparative detonations and power with fuel octane reduced by Parafin between inclined valve head with dry liner cylinder blockm cast iron cylinder block and then with standard Bentley unit. Power drop to cut out detonation in each case to be taken. RmL.H.Swindall. | ||
