| 摘 要： | 在直喷式车用柴油机的各种稳态工况下测量了排气微粒、微粒的不可溶组份和微粒的可溶组份的排放规律。试验结果表明，微粒的可溶组份主要产生于中、小负荷。微粒的不可溶组份峰值在大负荷，随空燃比减小而增加。

| Abstract: | Particulates and their insoluble fraction (mainly dry soot) and soluble organic fraction were measured under a variety of steady state operating conditions from an automotive direct injection diesel engine. It was found that soluble organic fraction is produced mainly under light load operating condition and dry soot increases with fuel air ratio. |
