| HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} c. to WB.{Mr Brazier/Mr Bell} Rm{William Robotham - Chief Engineer}/CTS{C. Trot Salt - Carburation}5/R.28.11.36. 4¼-LITRE BENTLEY. OVERHEAD CAMSHAFT ENGINE. We wish to test for reliability the conversion scheme for the above engine. To do this, it is not necessary to use a complete engine. It is, therefore, proposed to run the necessary parts in the form of a rig in W. Bell's department. It will be required, however, to build an engine, leaving out as many standard parts as possible. The crankshaft journals can be sealed, so that the main bearings receive their normal oil supply, and the cam-wheel will be driven normally through the usual spring drive. The crankshaft is then driven by electric motor. Will you please instruct the necessary parts to build this engine. W. Bell should let Rm.{William Robotham - Chief Engineer} know what new parts he would require for the rig. CTS.{C. Trot Salt - Carburation} | ||
