| 摘 要： | 针对LPG单燃料发动机,基于旋转坐标系的独立气缸模型,提出了一种采用λ型氧传感器的稀薄燃烧控制策略,大大降低了线性氧传感器所带来的高昂成本,并实现了燃气喷射的逐缸控制。试验结果表明,该控制策略在满足系统动力要求的前提下,大大降低了燃气的消耗及废气的排放,具有良好的应用前景。

| Abstract: | For the LPG engine and the independent cylinder model based on the rotary coordinate system,the lean-burn control strategy using oxygen sensor was introduced.The high costs of using linear oxygen sensor and the cylinder-by-cylinder control of fuel injection was realized by using the strategy.Test results indicate that the control strategy is helpful to reduce the consumption of gas and the emission of exhaust gas on the condition that the power of system is satisfied. |
