Abstract
An appropriate configuration of square cavities shows two distinct characteristics when compared with the characteristics of the circular cavity. One is that the injection angle to the square cavity wall has some effect on reducing smoke level at low engine speeds and loses this effect with increasing engine speed. Secondly, the reduction in swirl at high engine speeds results in a better balance of swirl over the entire engine operating range. This allows best injection timing for BMEP to be retarded resulting in lower NOx and noise.
