The fuel is converted in an exothermic reaction for achieving a specified setpoint temperature of a component to be heated. The required metering quantity of the fuel is calculated with the inclusion of a model of the exothermic reaction. The method makes it possible to achieve the specified setpoint temperature of the component to be heated or of the exhaust gas in front of the component to be heated using a minimal quantity of fuel.

Abstract: A procedure to operate a particle filter disposed in an exhaust gas area of an internal combustion engine and a device to implement the procedure are proposed. The particle filter is regenerated if required by the particles lodged in the filter, whereby the particle filter is heated for regeneration by manipulation of the exhaust gas temperature upstream in front of the particle filter. During the regeneration of the particle filter, the exhaust gas temperature is established to a specified exhaust gas temperature set point, which is dependent upon at least one parameter of the particle filter during the regeneration. The procedural approach according to the invention allows for a quick regeneration of the particle filter without endangering the particle filter with an inadmissibly high temperature.

Abstract: A procedure to operate a metering device of an exhaust gas emission control system of an internal combustion engine and a device to implement the procedure are proposed. At least one component in an exhaust gas emission control configuration of the exhaust gas emission control system requires at least in certain operating conditions a reagent substance, which the metering device provides, in which a connecting line is disposed. After the emergence of a metering demand signal a reagent substance rate-set point is established. The reagent substance rate-set point is either established immediately when the metering demand signal occurs and subsequently no longer changed until the connecting line is filled with the reagent substance; or the reagent substance rate-set point is only then established if the connecting line is filled with the reagent substance. An overdose of the reagent substance is avoided with the procedural approach according to the invention.

Abstract: The invention relates to an exhaust gas aftertreatment device for an internal combustion engine supercharged in two stages, having an oxidation catalyst, a particle filter, and a metering device for introducing a regeneration agent into an exhaust gas system, and to an associated method for exhaust gas aftertreatment. According to the invention, the metering device is arranged in the exhaust gas system between a high-pressure turbine and a low-pressure turbine which produce two-stage supercharging of the internal combustion engine.

Abstract: The invention relates to a method and an apparatus for temporarily increasing the temperature in the exhaust gas of an internal combustion engine, comprising at least two associated turbochargers with a respective compressor in a fresh air feed to the internal combustion engine and a respective turbine in an exhaust gas line of the internal combustion engine, wherein a bypass is assigned to at least one compressor and/or one turbine, and comprising at least one exhaust gas retreatment system connected downstream of the turbines in the exhaust gas direction. In this case, the volumetric flow of fresh air and/or of exhaust gas directed past at least one compressor and/or one turbine through the bypasses is increased via regulating elements in the bypasses, which leads to a reduction in the charge pressure and hence to a reduction in the efficiency of the internal combustion engine and to an increase in the exhaust gas temperature.

Abstract: The invention concerns a method for the closed-loop control of the regeneration of a particle filter in the exhaust gas system of an internal combustion engine, wherein the burn-off of particles in the particle filter during a regeneration process is controlled by a closed-loop control of the oxygen content of the exhaust gas and/or wherein the temperature of the exhaust gas or of at least one component of the exhaust gas aftertreatment system is controlled in a closed loop. Provision is thereby made for the corrective controller actions for the closed-loop control of the oxygen content and/or the temperature of components of the exhaust gas aftertreatment system to take place only during stable combustion conditions of the internal combustion engine.

Abstract: The invention concerns a procedure to control a regeneration of a particle filter in an exhaust gas purification system of a combustion engine, at which combustion air inlet is supplied via a combustion velocity supply duct with a butterfly valve and at which exhaust is recycled in an exhaust duct via an exhaust gas recirculation and/or a low pressure-exhaust gas recirculation, by which exhaust can be supplied to the combustion velocity supply duct. If the gearings of the butterfly valve and the exhaust gas recirculation and/or the low pressure-exhaust gas recirculation are conducted in a pre-defined sequence, it can be reached, that the particle filter is protected from damages because of overheating and at the same time the ease and convenience when driving is not affected.
