概要

In the previous report, it was shown that generating strong turbulence late in the combustion period was very effective for the reduction of smoke. In the present report, the efforts were more concentrated on the reduction of NO_x. It was attempted to apply EGR and water injection into the intake manifold, as well as generating strong turbulence. As a result, it was found that strong turbulence combined with EGR in a partial load and with water injection in a heavy load greatly reduced smoke and NO_x simultaneously. The effects of this system on particulate emissions and its physical mechanism in smoke reduction were also discussed.
