For brevity, only the 2000 rpm test results will be presented. The same trends were observed at 1400 and 1700 rpm test conditions.

Performance and Emissions - The performance and emissions results at 2000 rpm are shown in Figs. 4 and 5. Fig. 4 is a plot of indicated thermal efficiency, smoke opacity, and particulates versus indicated power for the six engine test conditions listed in Table 2. The three insulated engine increased coolant temperature tests are designated "Ceramic Hot Test" in the figures. Increasing the baseline engine coolant temperature from 180°F to 220°F
