Book Description
A single cylinder diesel engine with simulated turbocharging was instrumented and run to acquire radiation data at two wavelengths, simultaneously at three locations, along with cylinder pressure data and injection data. The 8 hole injector was indexed to acquire data, at three angles of 0, 11, 22.5 deg from the spray axis. The engine speed was 1500 rpm, the equivalence ratio (based on fuel to oxygen ratio) was 0.47, and the partial pressure of oxygen was 58 kPa for all runs. The radiation data were processed to produce the flame temperature and soot concentration using the two-color theory. The soot concentration and temperature increased in the outward radial direction, with the highest values at the 11 deg location except for near the injector where the highest values were on the axis.

Book Description
Performance and emissions data were gathered on a normally aspirated single cylinder DI engine with various combinations of ceramic coatings installed. Thin ceramic thermal barrier coatings were applied to the piston crown and bowl, the head and valves, and the cylinder liner. The coated piston and head were run singly and in combination with the cylinder liner to investigate the effects of these different coated surfaces on emissions and performance. Coating the piston crown alone results in generally lower cylinder pressure, lower brake specific fuel consumption and lower NO(x) emission compared to the baseline engine. Soot emission is typically increased below 2000 RPM and decreased above 2000 RPM. Coating the head alone reduces cylinder pressure, but generally increases specific fuel consumption and NO(x) and soot emission. The KIVA-II code was used to model the Hydra engine with the thermal coatings. The computer modeling has led to an understanding of the effect of coating the piston on NO production. The hotter piston crown warms the intake air, shortening ignition delay and decreasing the ratio of premixed to diffusion combustion, ultimately resulting III lower peak cylinder temperature and reduced NO. The KIVA-II results agree reasonably well with the experimental data for cylinder pressure and NO and soot emission.
