So far as practical considerations are concerned therate of burning can be reduced, and at the same timestable conditions of running can be maintained, only byworking on the rich side of the range. Under these con-ditions, however, the power output and economy ceaseto rise with increase of compression because the timeof ignition or the mixture strength is no longer the mostfavorable. By further enriching the mixture and re-tarding the ignition, the compression can be increasedto as high as 5.4:1, but, of course, only at great sacrificeof economy. The m.e.p. and thermal efficiency curvesobtained from such a test are shown in Fig. 2. It will be observed that, although the first indicationsof detonation occurred with a compression ratio of about4.75:1, it is possible by suitable adjustments of the mix-ture strength and ignition timing to raise the compres-sion to as high as 5.4:1 without allowing the detonation 60 P55 ua 50 40 35 4 0 50 55 GO 65 70 75 Text Appearing After Image: Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.

CHAPTER XIX THE BEARING OF AUTOMOTIVE TRANSPORTATION UPONTHE OIL INDUSTRY There is no industrial parallel to the growth in output of pas-senger cars, trucks and tractors in the United States during the pastten years. The expansion of automotive transportation is one ofthe remarkable features of the twentieth century. The number ofcars, trucks and tractors produced annually in the United Statesfrom 1910 to 1920 is shown in Table 115. The approximate number of motor vehicles Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
