    摘要： An engine exhaust system comprising an exhaust pipe routing an exhaust flow through a bend, and being in fluid communication with a catalyst downstream of the bend. An injector mounted to the exterior of the exhaust pipe, the injector with a tip disposed within the exhaust pipe at the bend, for injecting liquid reductant into the exhaust pipe. A shield member mounted in the exhaust pipe, the shield member comprising a generally tubular or frustoconical structure having proximal and distal end, the proximal end being disposed such that the injection tip is inside the shield member, the distal end being disposed towards a centerline of the exhaust pipe. A vane mounted in relation to the shield member, the vane being arranged to direct a proportion of exhaust flow from upstream of the bend in a substantially arcuate path into the proximal end of the shield member.

    摘要： A controller for a common-rail injection system includes a plurality of fuel injectors, a common fuel supply line for the fuel injectors, a high-pressure pump for supplying the common fuel supply line with fuel, and a pressure sensor for determining the pressure in the common fuel supply line. A determination unit evaluates data of the pressure sensor and, from the pressure drop caused by an injection in the common fuel supply line, determines the fuel quantity actually injected during this injection or a value derived therefrom. An adaption unit uses the results of the determination unit in order to adapt the actuation of the fuel injectors. The determination unit carries out at least one test injection, and the actually injected fuel quantity or a value derived therefrom is effected by way of the test injection or injections.
