摘要
针对共轨式电磁喷油器驱动技术的灵活可调和高可靠性等特点,提出了一种新型的电磁喷油器驱动单元。该单元采用智能化驱动芯片MC33800和可编程逻辑器件CPLD,兼备故障智能化诊断的功能。通过试验验证了该单元对电磁喷油器的适应性,能实现预定的功能和性能,具有很好的集成度和可靠性。
In view of the flexible, adjustable and highly reliable characteristics of common-rail electromag- netic injector drive technique, a new type of electromagnetic fuel injector drive unit is proposed, which uses intelli- gent driver IC MC33800 and programmable logic element CPLD and has the function of intelligent fault diagnosis. The test results verify that the drive unit suites to the electromagnetic injector and can achieve the intended function- ality and performance with high reliability and the degree of integration.
