| P. FROM E.{Mr Elliott - Chief Engineer} ORIGINAL SECRET. E2/W5.3.31. C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} C. to HS.{Lord Ernest Hives - Chair} BY.{R.W. Bailey - Chief Engineer} JAPAN 3. INDUCTION SYSTEM. X5070. X5080. Please find herewith a print of LeC. 2881. shewing a preliminary arrangement of the above made primarily to shew its connection to the exhaust port provided on the inlet side of the cyl. head. It is assumed in this drawing that we are likely to use the standard type of RR. carburetter and induction pipe to begin with, or at least it should be made possible to do so. The carburetter and pipe are suitably scaled up from the 20/25. to suit the increased output. The carburetter will no longer go down behind the steering box and has been raised nearly 3" compared with Japan. This enables it to be very conveniently drawn off its fixing flange when dismantling over the top of the steering box. With regard to the fuel supply it is assumed that to begin with an autovac will be used. With the position of carburetter shewn we should still be better off than P. 2. as regards feed head when climbing a steep gradient. A print of LeC. 2881. is attached to BY's copy of this memo.
