March 11th, 1932. SAFETY FUEL. ----------------- We went over to the Standard Oil Co's offices in New Jersey to get details of the Safety Fuel and the conditions under which this is being used. The specification of the fuel is as follows :- High Thermal Value 19,750 B.Th.U's. Flash Point Minimum, 105ºF.{Mr Friese} Octane 90 Mins at 300ºF.{Mr Friese} 800 R.P.M. Initial 300ºF.{Mr Friese} Final 400-410ºF.{Mr Friese} Sp.{Mr Spinney} Gr.{George Ratcliffe} .838 The fuel naturally has disadvantages with regard to starting, and some experimental tests have been conducted which show that a vapouriser is necessary if the fuel is to be used with a normal carburetter. However, the main application of the fuel at present is for use in petrol injection systems. The production of the fuel has not yet reached a stage where it can be bought over here commercially, though it is being supplied to the American army. It will, however, be available in bulk in about three months time. We have procured a sample of this fuel. Hs.{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
