摘要
点火系统是发动机的重要主成部分,对发动机的性能有绝对性的影响;在开放式ECU的基础上进行了点火正时策略的设计以及预标定的工作,大大缩短了开发的难度和周期;对某LNG气体机的点火正时策略进行了设计和优化,并结合发动机计算模型(进气,压缩,做功,排气)进行了反馈和验证;使用开放式ECU进行实验开发,可以为实验节省大量的时间和资源,监测不同的输入条件对点火提前角的影响,实现了脉谱的预标定,大大缩短了开发工作,具有一定的实际运用价值。
Ignition system is the main important part of the engine, and has absolute influence on engine performance. Open ECU for ig- nition timing strategy on the basis of the design and calibration work, greatly shorten the development difficulty and cycle; Machine of a LNG gas ignition timing strategy has carried on the design and optimization, and combining the calculation model for the engine （air intake, com- pression, power, and exhaust） feedback and verification. It can save a lot of time and resources for experiment if experiments use open ECU. It also can monitor the influence of the different inputs conditions on the ignition advance angle, It has realized the pulse spectrum of calibration, greatly shorten the development work and has certain actual application value.
