摘　　要：研制了一种在发动机台架上进行柴油机瞬态工况控制及排气微粒测量的测试系统 .该系统主要由普通电涡流测功机、简单电控系统、A/D采集板和微粒稀释取样袋等组成 .此系统可实现柴油机一些基本瞬态工况的控制。A system for engine control and exhaust particulate measurement of an automotive direct inject (DI) diesel engine under transient operating conditions was developed, which includes a conventional dynamometer, a simple electronic control system, an A/D converter and a dilution sampling bag. This system can be used to accomplish the real-time data acquisition, measurement of particulate emission and control of basic transient operating modes.
