The pumping assembly comprises drive means comprising a drive plate (114) rotatable about a drive axis (A) and including a recess (120) arranged eccentrically with respect to the drive axis (A); a guide arrangement (122, 122a) received, at least in part, in the recess (120) of the drive plate (114) so that rotary movement of the drive plate (114) gives rise to translatory movement of the guide arrangement (122, 122a); a pumping element (108); and a slide member (112) associated with the pumping element (108). The slide member (112) is in sliding engagement with the guide arrangement (122, 122a) to define at least one sliding interface (196, 198) between the guide arrangement (122, 122a) and the slide member (112), such that rotary movement of the drive plate (114) causes reciprocal linear movement of the pumping element (108) along a pumping axis (Q).

摘要： A method of controlling NO x emissions in an internal combustion engine is proposed, wherein the engine comprises an exhaust system with oxidation - promoting catalyst means (22) having a NO oxidation efficiency, and wherein the engine is normally operated on a map of normal EGR rates. The engine is operable in a NO 2 -promoting mode that comprises the steps of:
determining whether operating the engine under a modified EGR rate would lead to an increased generation of NO 2 , said determination taking into account the variability of the NO oxidation efficiency with the oxidation temperature and the exhaust flow rate; and
using the modified EGR rate for engine control in case it leads to an increased NO 2 generation.摘要翻译： 提出了一种控制内燃机NOx排放的方法，其中发动机包括具有NO氧化效率的氧化促进催化剂装置（22）的排气系统，并且其中发动机通常在正常EGR 率。 所述发动机可在NO 2引燃模式下操作，包括以下步骤：确定在改进的EGR率下是否运行发动机将导致NO 2的产生增加，所述确定考虑到NO氧化效率的变化性 氧化温度和排气流量; 并且在引起NO 2产生增加的情况下使用改进的EGR率用于发动机控制。

摘要： A reagent dosing system (10) for an internal combustion engine having an exhaust pipe (20) and a pump are disclosed. The reagent dosing system (10) comprises a first pump (26) having input means (30) for receiving reagent from a reagent supply (22) and output means (32) for delivering the reagent to a supply line (28), and a fluid dosing device (12) downstream of the first pump (26), comprising a nozzle (16) and a second pump (14) for receiving the reagent from the supply line (28) and for delivering the reagent to the nozzle (16), the second pump (14) being operable to increase the pressure of the reagent in the nozzle (16) to an injection pressure so as to cause delivery of the reagent through the nozzle (16). The first pump (26) is operable to increase the pressure of reagent in the supply line (28) to a pressure that is less than the injection pressure so as to guard against overheating of the reagent in the supply line (28). A pump (100) according to the invention is arranged such that, when the pump is not operating, an outlet valve means (135) of the pump is held in an open position so as to allow reagent to flow from the inlet means (102) to the outlet means (104) through the pumping arrangement (108, 154).
