on. It may be seen from Figure 4 that the optimum ignition timing for this method of control, and also for the method discussed below in which the inlet-valve timing was varied, approximates, for the various compression ratios, the optimum ignition timing determined for the nondetonating fuel. The… … Compression ratio Fig. 5.—Inlet-valve timing used for conditions (S) and (4), Figure 4 this method varied but slightly from 30°. The permissible power output at a compression ratio of 7.3 is seen to be about 40 per cent less than obtained by maintaining full throttle and retarding the ignition. The…
