Abstract: 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.

Abstract: 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).

Abstract: An exhaust system (16) for a compression-ignition engine (10) includes an exhaust gas after-treatment assembly, the after-treatment assembly comprising a catalyst device and an SCR device (34). The catalyst device comprises a three-way catalyst device (30) arranged upstream the SCR device (34) in close-coupled position with respect to the engine (12). The three-way catalyst reaches its operating temperature quickly due to its close coupled position and can therefore provide good NO x conversion during acceleration phases occurring shortly after a cold start when the engine is switched to an operation at λ=1.

Abstract: A fuel injector (100; 200; 300) for an internal combustion engine is disclosed. The injector includes a slave piston (130; 230; 330) provided with a control bore (144; 244; 344) and associated with a valve needle (110; 210; 310), such that movement of the slave piston causes movement of the valve needle. An end of the slave piston remote from the valve needle is exposed to fuel pressure in a control chamber (152; 252; 352) of the injector, in use. A control piston (148; 348) is operable to move relative to the slave piston so as to control fuel flow through first and second control ports that connect the control bore to a high-pressure fuel supply and a low-pressure drain respectively. By suitable positioning of the control piston, the valve needle can be biased in an opening direction and in a closing direction and, optionally, the valve needle can be held in one or more intermediate positions between its fully-lifted and fully-seated positions. Proportional control of the position and velocity of the valve needle is possible, and a low-force actuator can be used to control the valve needle.
