    • The invention relates to an internal combustion engine comprising a high-pressure accumulator injection system wherein the swept volume and the pressure are regulated by means of a volume flow control valve (VCV) and a pressure control valve (PCV). The inventive method consists in checking, during the overrun condition of the internal combustion engine, whether predetermined release conditions for carrying out the diagnosis are fulfilled, and in the event of a positive result, the control valve (VCV) is closed for a predetermined period of time (t1). During said period (t1), values relating to fuel pressure (FUP) are detected by means of the pressure sensor (21) and compared with a predetermined threshold value (FUP-SW), the control valve (VCV) being deemed faultless if said fuel pressure (FUP) values are sufficiently often below the threshold value (FUP_SW) during the cited period of time (t1).
    • 本发明涉及一种内燃机,其包括高压蓄能器喷射系统,其中扫气体积和压力通过体积流量控制阀(VCV)和压力控制阀(PCV)来调节。 本发明的方法在于,在内燃机的超速状态期间,检查是否满足了用于执行诊断的预定释放条件,并且在积极结果的情况下,控制阀(VCV)关闭预定时段 的时间(t 1)。 在所述时段(t 1)期间,通过压力传感器(21)检测与燃料压力(FUP)相关的值,并与预定的阀值(FUP-SW)进行比较,如果控制阀(VCV) 所述燃料压力(FUP)值在引用的时间段(t 1)期间足够经常低于阈值(FUP_SW)。
