共轨高压泵总是保持在压力，导致燃油的浪费和的燃油温度。共轨系统为商用车设计的，喷射压力为140MPa，乘用车喷射压力为135MPa。
共轨系统可根据发动机需求而改变输出压力，并具有预喷射和后喷射功能。带有控制油量的油泵，喷射压力能达到160MPa。即使在压力较低的情况下，该系统也可以根据实际状况提供适量的喷油压力。不仅有助于降低燃油消耗，而且还可以降低燃油温度，从而省去燃油冷却装置。预喷射降低了发动机噪声：在主喷射之前百万分之一秒内少量的燃油被喷进了汽缸压燃，预热燃烧室。预热后的汽缸使主喷射后的压燃更加容易，缸内的压力和温度不再是突然地增加，有利于降低燃烧噪音。在膨胀过程中进行后喷射，产生二次燃烧，将缸内温度增加200～250℃，降低了排气中的碳氢化合物。
共轨系统带有压电直列式喷油器。共轨系统面世，压电式（piezo）共轨系统的压电执行器代替了电磁阀，于是得到了更加的喷射控制。省去了回油管，在结构上更简单。压力从20～200MPa弹性调节。喷射量可控制在0.5mm3，减小了烟度和NOX的排放。喷射压力达到180MPa。此套采用新研发的压电直列式喷油器的系统使带预喷和后喷的喷油率曲线范围更为自由。
与其它喷射系统相比，共轨系统把压力产生与实际燃油喷射过程分离。“轨”被作为高压蓄压器，其内部燃油压力始终保持与发动机具体工况相适应的压力。共轨系统可被轻易地安装到各类不同的发动机中。除此之外，共轨系统还提供了更广阔的扩展功能和在燃烧过程设计上更多大的自由度，它可以使柴油发动机以的排放、的燃油经济性和低噪声运行。
德尔福柴油机共轨喷射系统所配备的共用高压燃油储能器，亦称为“共用油轨”。通常被设计装配在发动机的气缸体或气缸盖上，由高压油泵向其提供高压燃油。共轨内部的燃油压力是通过发动机电子控制模块结合设计在高压油泵内部的进油计量装置和高压燃油调节器（当系统装备时）完成综合调节控制的。因此，系统燃油压力与发动机转速无关。即使在很低的发动机转速下，如果需要，系统也可以提供高压燃油并进行高压燃油喷射。一组若干个高压燃油喷射器将通过高压油管与共轨相连接。系统通过发动机电子控制模块直接驱动设计在燃油喷射器内部的电磁开关控制燃油喷射的开启和关闭时间和频率。
德尔福柴油机共轨喷射可非常方便地扩展应用到中型车辆柴油机以及非车用柴油机市场产品上。
