    Abstract: A method for controlling temperature of a gas post-treatment system in an exhaust circuit of a thermal engine having a more or less rich combustion mode, in which at least a post-treatment member is periodically submitted to regeneration phase at a set-point temperature. The duration of each regeneration phase is divided into a series of fractioned periods for tuning the engine alternatively according to two combustion modes each having a different richness, respectively a mode hotter than necessary for reaching the set-point temperature and a mode that is not so hot, the duration of each period being controlled so that excess energy introduced during a hotter mode period is compensated by the lack of energy in the following period with the less hot mode, and conversely, to maintain at the output of the post-treatment member a mean temperature corresponding to the set-point temperature.

    Abstract: A method to dislodge an adherent residue in an EGR cooler, the EGR cooler installed in an engine. The method comprises flowing an exhaust gas through an adherent-residue bearing surface of the EGR cooler when a temperature of the adherent-residue bearing surface is below a dewpoint temperature of the exhaust gas, enabling water vapor from the exhaust gas to condense on the adherent-residue bearing surface, heating the adherent-residue bearing surface to above the dewpoint temperature of the exhaust gas, and enabling condensed water on the adherent-residue bearing surface to evaporate. Other embodiments provide a method to recirculate an exhaust gas from an exhaust port of an engine to an intake of the engine via an EGR cooler, and a related EGR system.

For example, according to one embodiment, an apparatus for controlling the temperature of the output exhaust of an internal combustion engine for a regeneration event on a particulate matter filter includes a regeneration module, a turbocharger thermal management module, a fuel injection thermal management module, and an air intake thermal management module. The regeneration module determines a desired particulate matter filter inlet exhaust gas temperature for a regeneration event.

The air intake thermal management module determines an intake throttle position strategy. The VGT device position strategy, the post-injection fuel injection strategy, and the intake throttle position strategy cooperatively achieve the desired particulate matter filter inlet exhaust gas temperature and maintain a fuel dilution level of the engine below a maximum fuel dilution level.

    Abstract: A conventional technique performs valve close control of an EGR valve after an EGR-gas back flow is detected. Therefore, the conventional technique has a subject that, if an EGR-gas flow direction changes from forward flow to back flow, a back flow condition will last not only for a response delay time of a detector but also for the judgment time by calculation processing and the actuation time of the EGR control valve. There is provided a control apparatus of an EGR control valve, comprising: an EGR control valve which is provided in an exhaust gas recirculation passage to circulate exhaust gas of an combustion engine from an exhaust gas passage to an intake air passage; measurement means for measuring a flow rate of EGR gas flowing in the exhaust gas recirculation passage; and control means for receiving an input from the measurement means and closing the EGR control valve if the EGR-gas flow rate is smaller than a predetermined threshold value when the EGR gas is flowing from the exhaust side to the intake side of the internal combustion engine.

    Abstract: A combustion apparatus such as a Diesel engine (16) in a motor vehicle (1) has an air inlet system (20,22) through which air can be drawn air from the atmosphere to the engine, a fuel supply system (28, 30, 32) for supplying fuel to the engine, and an exhaust system (34, 36, 38, 40, 42) for exhausting combustion gas from the engine to the atmosphere. A heat exchanger (48) is provided between the exhaust system and the fuel supply system so that heat is transferred from the exhaust gas to the fuel so as to warm the fuel and thus improve the combustion efficiency of the engine. When applied to a conventional layout of motor vehicle the heat exchanger can conveniently be disposed beneath the vehicle away from the engine compartment so as not to cause overcrowding thereof. The heat exchanger may form part of an EGR system (44,46) for feeding a proportion of the exhaust gas from the exhaust system to the air inlet system so as to cool the recirculating exhaust gas and thus enhance the reduction of NO and NO2 emissions.

    Abstract: An abnormality determination device for an EGR device, which is capable of determining the abnormality of the EGR device properly without interrupting the EGR operation. An ECU of an internal combustion engine detects an amount of fresh air drawn into a combustion chamber of the engine, carries out feedback control of the fresh air amount such that the detected fresh air amount converges to a predetermined target fresh air amount by controlling an opening of a throttle valve disposed in an intake system of the engine during execution of EGR by the EGR device. The ECU obtains a decreasing degree parameter which represent a degree of decrease in the fresh air amount caused by the feedback control, and determines abnormality of the EGR device based on the obtained decreasing degree parameter.
