| contd :- -8- oil pressure. this factor becomes of significance where previously it could be neglected. Amongst other things the initial ignition advance is delayed as the load does not start to lift until gap G.{Mr Griffiths - Chief Accountant / Mr Gnapp} has attained measureable dimensions. (b) Variation with speed. This can almost be accounted for by the increase in oil pressure with speed. Thus in a certain case | R.P.M. | Load lifted. max. | Oil Pressure. | % difference. | |---|---|---|---| | | | | Oil pressure. | Lift. | | 1000 | 50 | 13.5 | 12% | 20% | | 1500 | 60 | 15 | | | The reason for the remaining small discrepancy is somewhat obscure.
