摘要
本文介绍了自行研制的CA488Q发动机空燃比及点火控制系统,详细介绍了系统的组成和空燃比及点火提前角的控制方法。台架实验结果表明,采用该系统后CA488Q发动机的动力性、经济性及怠速稳定性都较原化油器发动机有明显的改善。
An integrated control system for CA488Q gasoline engine is introduced and analyzed. Several control functions, such as air-fuel ratio, ignition advance angle and idling speed, etc. can be performed by the system. The construction of the system and the algorithm of controlling the air-fuel ratio and ignition advance angle are discussed in detail. From dynamometer tests, it is shown that the power performance, fuel economy and idling stability of the engine are improved obviously.
