摘要
为了满足多次喷射技术对高压油泵泵油提出的新要求,该文基于GD-1电控柴油机高压油泵设计了适应于多次喷射的控制策略,并在发动机台架上对其进行了试验验证。试验结果表明,该控制系统实现了对高压油泵的有效控制,最大限度地发挥出高压油泵的优越性能,并有效保证整个电控喷油系统的可靠性,为进一步改善高压共轨式柴油机的多次喷射控制和降低柴油机的排放提供了良好的基础。
In order to meet the new requirements of multiple injections technology on high pressure pump,the control strategy based on high pressure pump of GD-1 electronic controlled diesel engine was designed and further tested on engine platform. The test results demonstrated that this control strategy achieved an effective control on the high-pressure pump,in which,not only the performance of high-pressure pump was improved,but also the reliability of fuel injection system was ensured. This control strategy can also provide a basis for common rail diesel engine to further improve the multiple injection control and emission.
