| 摘 要： | 设计了电控单体泵预喷射时序控制算法,开发了基于MPC563微控制器的控制器数字系统,考虑预喷射量和主预喷间隔的要求、单体泵凸轮供油段长度限制等因素,在单体泵试验台上进行了预喷射探索试验.试验表明:预喷射会在高压油管内形成压力波动并影响主喷射；压力波动循环间变动小；随着转速升高压力波动逐渐减小；在转速低于1 200 r/...

| Abstract: | The algorithm of pilot injection sequential control for electronic unit pump was designed and the controller digital system was developed based on MPC563.The experiment was carried out on a test bench considering both requirements of pilot injection quantity and main pilot injection interval and cam profile limitation.The result shows that the pilot injection causes the pressure fluctuation in the high-pressure fuel pipe and influences the main injection.The variation between pressure fluctuation cycles is ... |
