共轨电控柴油机喷油压力控制与对策

The control and countermeasure of common rail electronic fuel injection pressure of diesel engine

油泵-溢流阀的调压系统最大的优点是结构简单、反应迅速、压力波动小,尤其采用直动式溢流阀,其特性优于采用先导型的溢流阀。

For pressure-regulating system of fuel pump-relief valve, its most advantages are simple structure, quick response and lower pressure fluctuation. Especially for the direct acting relief valve, its characteristic is better than pilot relief valve.
