| COPY OF MEMORANDUM Bt {Capt. J. S. Burt - Engineer} 1/IN/17.3.26. Y EXHAUST EXPLOSIONS IN NEW PHANTOMCodename for PHANTOM I CAR. In reply to your questions in BJ5/H17.3.26. My experience is that it is the rule to get these explosions. They are minimised greatly by driving with the hand control of the throttle above the steering wheel in the closed position, but this is tiresome in traffic. I think I can say that though they vary, these explosions were present on every Phantom I've driven. The following is a list of those cars which are known to Inspection Department as having caused complaint by their owners or drivers in this respect:- 118-MC 91-MC. 79-HC. 63-MC. 9-MC. 43-MC. 45-MC. 113-MC. 49-MC. 86-HC. 117-MC This is one of the features that we are less successful with on the Phantom than on Silver Ghost, and I have wondered if it would be practicable to increase the size and power of the governor lever gear to overcome the increased resistance of the butterfly throttle we now fit in place of the piston throttle which we had to keep bright and clean on the Ghost. Bt. {Capt. J. S. Burt - Engineer} COPY OF HAND WRITTEN MEMO. FROM H. {Arthur M. Hanbury - Head Complaints} 3.3.26. By no means exception. Compared with Ghost very marked. Hand throttle must be kept shut always but am doubtful if control on wheel always succeeds in shutting it. 7-LC. 8-LC. (Sgd.) H. {Arthur M. Hanbury - Head Complaints} | ||
