The Relationship

The rates of injection and heat release of two designs of indirect-injection diesel engines have been studied over a range of speed, load, and timing. The relationship between these two quantities is significantly different from that previously found for open-chamber engines. It is suggested that only part of the air is available for mixing in a divided-chamber engine, and the movement of the piston controls to some extent the availability of the remaining part of the air. A semi-empirical scheme is proposed for relating the rate of injection to the rate of heat release for this type of engine.

Adequate Data

The effect of inlet temperature, pressure, air flowrate and fuel-to-air ratio on NOx emissions from gas turbine combustors has received considerable attention in recent years. A number of semi-empirical and empirical correlations relating these variables to NOx emissions have appeared in the literature. They differ both in fundamental assumptions and in their predictions. In the present work, these simple NOx correlations are compared to each other and to experimental data. A review of existing experimental data shows that an adequate data base does not exist to evaluate properly the various NOx correlations. Recommendations are proposed to resolve this problem in the future.
