| 摘 要： | 试验研究了CA6DE1-21K柴油机在恒转速变转矩和恒转矩变转速瞬态工况下NOx的排放规律．研究结果表明，在恒转速变转矩瞬态工况中，NOx瞬态排放值低于其在稳态工况下的排放值，且与转矩变化率的变化关系不大．在恒转矩变转速瞬态工况中，中低负荷时NOx排放值随着转速变化率的升高而上升，而在中高负荷时，工况的变化率对NOx排放影响不大。

| Abstract: | Thraugh an experiment conducted on the NO_x emission behavior from CA6DE1-21K diesel engine under transient operating conditions, it is investigated that under constant speed increasing torque transient operating conditions, NO_x (emission) is lower than that under static operating conditions, and torque increasing rate does not have obvious effect on NO_x emission. Under constant torque increasing speed transient operating conditions, NO_x emission increase with the growth of engine speed increasing rate() for low loads, and do not have obvious effect on NO_x emission under high load conditions. |
