摘要
建立了柴油机高压共轨系统喷油规律测试试验平台,为加快共轨系统研发提供了一种有效的测试试验手段.对高速电磁阀喷油器系统的喷油规律、液力系统响应时间及预喷主喷控制进行测试.试验结果表明:共轨系统可以柔性控制喷油规律形式,其系统响应时间可达0.61 ms,预喷射最小达每循环6 mm3.
A test bench is build up for testing common rail injection rate of diesel engine. Injection rate of electronic injector system, dynamic response and control of pre-injection and main injection are tested respectively. The results show that flexible injection control can be got by the common rail system; the dynamic response time is 0.61ms and pre-injection is 6mm^3 per circle.
