✦ Synopsis

The effect of injection nozzle, diesel fuel density (volatility) and cetane number on diesel exhaust emissions were investigated. Decreasing injection nozzle hole diameter decreases PM emission. However, a small nozzle hole increases NO x emission and decreases the effect of fuel on PM emission. Decreasing fuel density is effective for reduction of NO x emission. But the effect is smaller than that of nozzle hole diameter and injection pressure. Furthermore injection timing retardation decreases the effect of fuel density on NO, emission, i~ 1998 Society of Automotive Engineers of Japan, Inc. and Elsevier Science B.V. All rights reserved.
