Following in order of urgency is the development work which we have on Induction systems and carburetters at present:- (1) Starting Carburetter for B.V. 200 sets have not yet been instructed for production. (2) A Starter Induction System for the 8-cylinder engine. We consider that before we standardise anything on the 8 we should get a system exactly like that on the Buick to see what advantages it has. The 8-cylinder car should be tried with a vacuum ignition advance, and we should not accept a worse consumption than that of the Buick with the same gear ratios and weight of car. (3) Duplex Induction System for 6-cylinder engines. We hope that this will become the standard system for 6-cylinder engines. We are particularly interested to know whether the economy obtainable on the two S.U's can be reproduced on the Duplex Stromberg. (4) Automatic Starting Device which is applicable to all Stromberg Carburetters. We want to know the merits or demerits of the electric starter. -------------------- Before we finalise any of these induction systems it is essential that the engine should be fitted with the correct camshaft for idling. It is also imperative that the best coil and distributor which is known to be reliable should be utilised. As far as possible when any carburetters or fuel consumption experiment is being carried out on the road, I should like all those concerned to know about it so that they may see it if they so desire. At the same time we should like the Garage people to be informed when an engine is being passed off the Test Bed with one of these induction systems so that they can take an interest in it and the development which has taken place up to road test. | ||
