es not only isthe efficiency on reduced loads far higher than could beobtained by any other means, but the heat loss is so lowthat a water-cooled engine can be run at reduced loadsfor any length of time without cooling water. The accompanying curve (Fig. 7) shows the efficiencyactually obtained in… … Fig. 8—Indicator card from experimental engine using excessair 0.36 pint of benzol per indicated horsepower-hour. It will be seen that the curve of efficiency actually obtainedfollows the theoretical curve with a reasonable degreeof approximation. In Fig. 8 is shown a typical indicatordiagram taken…
