摘要： A method of operating an internal combustion engine is proposed, the engine comprising an exhaust system with a DOC and a DPF and, downstream thereof a SCR catalyst. The ECU is configured to allow operation in at least one of a normal mode and a heat-up mode. A predicted temperature evolution of said second exhaust after treatment means is regularly determined based on a thermal model taking into account the thermal inertia of the exhaust system and having as input the current temperatures of the DOC/DPF and SCR. The predicted temperature evolution of SCR is indicative of the temperature that the SCR may reach during a simulated time period in case the operating mode. The engine operating mode is changed depending on the predicted temperature evolution.

摘要： A serviceable filtration arrangement for use in an internal combustion engine of a vehicle to remove contaminants from a liquid to be filtered. The filtration arrangement (1, 101) comprises an upstream filtration element (7,107) and a downstream filtration element (5,105). Upon servicing of the vehicle the upstream filtration element (7,107) can be replaced independently of the downstream filtration element (5,105). The upstream filtration element (7,107) has a filtration media (61) which has characteristics that have been selected such that the upstream filtration element (7,107) becomes clogged before a filtration media (51) of the downstream filtration element (5,105) becomes clogged.

摘要： A method of assessing the functioning of an EGR cooler of an EGR system in an internal combustion engine, wherein the EGR cooler can be selectively operated in a first and a second operating condition; and wherein the engine comprises at least one cylinder equipped with a pressure sensor. The assessment of the functioning of the EGR cooler is based on the variation of a combustion characteristic value depending on cylinder pressure (CA50), upon switching of the EGR cooler from a first to a second operating condition.
