The other breakdown I refer to is the broken connecting rod, which was probably due to running in the reverse direction, but might have been due to the piston belonging to the articulated rod becoming excessively tight. This subject will bear investigation, and for your part I reccomend that one of the pistons only on an engine be made larger that the other eleven, in fact, so large in the top that you know that when the throttle is suddenly opened it will probably pull up the engine with its tightness. We can then let this piston be fitted to an articulated rod, and can pull up the engine a few times with this piston, providing nothing breaks on the first occasion. Should the piston or connecting rod give way, the experiments will be fairly conclusive and very instructive. F.H.R. | ||
