德尔福直接驱动式共轨系统

Delphi Direct Acting Common Rail system

德尔福新款直接驱动式共轨系统代表了柴油喷射技术的又一个根本性的突破,因为喷油器针阀首次由压电晶体直接驱动,免除了的液压回路,及其相关的迟滞和能量消耗,并且为发动机的设计者提供了众多的附加控制的可能性。

The new Direct Acting Common Rail from Delphi represents a further radical break-through in diesel injection technology as for the first time the injector needle is directly activated by the piezo stack, removing the hydraulic circuit and its associated lag and energy consumption and providing significant additional control possibilities for engine designers.
