本文介绍了用子顾氏系统（即一种集配气与供油正时控制于一体的柴油机多变量同轴化控制系统）的上下两级电子控制系统的软硬件构成及其实时控制应用。试验表明，该系统具有设计合理、功能较强等特点，不仅能用于顾氏系统，还对内燃机其它测控项目具有较强的适应性。 This paper introduces the hardware and software composition and real-time control of the upper and lower electronic control systems with sub-Gu’s system (that is, a diesel multivariable coaxial control system integrating gas distribution and fuel timing control). The test shows that the system has the characteristics of reasonable design and strong functions. It can not only be used in Gu’s system but also has strong adaptability to other measurement and control projects of internal combustion engine.
