| TO HS.{Lord Ernest Hives - Chair} FROM Re EP{G. Eric Platford - Chief Quality Engineer} Cc. to Wor.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} BJ. Rg.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} X8080 R4/M18.5.26. re. EXPLOSIONS IN SILENCER. -X.8080. X893 X8230 7.EX. is a particularly good car for this, and there are reasons to believe that explosions in the silencer are largely influenced by the working of the carburetter when the throttle is nearly closed, that is to say, a good slow running engine with a carefully set carburetter and an induction pipe free from leaks will be less troubled with explosions in the silencer than a bad slow runner. This idea might be tested out because it may be that in cases of complaint the particular car is not in good slow running condition for some of the reasons too numerous to mention My own experience is that the Phantom have never been distinctly bad except with the cutout open, but if the carburation or ignition or any other parts of the engine, pistons, and valves are not in good order I then believe the phenomenon can be a nuisance. I should like HS.{Lord Ernest Hives - Chair} or RM.{William Robotham - Chief Engineer} to examine my 7-EX. when one of them next visits WW. Re | ||
