Abstract: A method for operating an internal combustion engine is proposed, in whose exhaust gas zone a particle filter is disposed, which is cyclically loaded with particles and thermally regenerated, as well as an apparatus for the implementation of the method, which prevents thermal overload of the particle filter after turning off the internal combustion engine. A test is made when the internal combustion engine is turned off to determine whether an exothermal reaction takes place. Provided that an exothermal reaction takes place in the particle filter, a butterfly valve is closed, which prevents exhaust gas flow through the particle filter and, if the circumstances arise, a resulting oxygenation ingress in the particle filter.

Abstract: The invention concerns a procedure and a device for controlling an air supply system of a combustion engine with an exhaust gas system and an exhaust gas purification system with a particle filter in the exhaust gas system, whereby a boost pressure of an air supply current is controlled or can be controlled in the air supply system over a combustion air supply duct with the aid if a throttle valve and/or an exhaust gas recirculation between the exhaust gas system and the combustion air supply duct. Regarding the procedure it is provided according to the invention, that the air supply current is determined directly before or during a regeneration of the particle filter by different means with the aid of signals from measuring devices that are arranged in the air supply system and/or sensors that are arranged in the exhaust gas system and that the results are compared to each other.

Abstract: A procedure for the operation of an internal combustion engine is disclosed, in whose exhaust gas area a particle filter is arranged which is freed from the stored particles during a regeneration. A measure for a load of the combustion engine is compared to a load threshold value. An overrun cut-off, at which the fuel metering is completely suppressed, is carried out if the measure for the load falls below the load threshold value and if the engine speed of the combustion engine lies above an engine speed threshold value. The load threshold value that has been determined to a value higher than zero is further dependant on the particle filter's regeneration signal. The procedure aims to prevent the overheating of the particle filter during its regeneration.

Abstract: A method for operating a drive train of a vehicle comprising an internal combustion engine (101) with an exhaust gas purification device (102) located in the exhaust gas line, characterized in that in predetermined operating states of the internal combustion engine (101) and/or of the vehicle a correction torque is imposed onto a desired torque (140) produced by an engine control unit in relation to said desired torque such that an output torque (110) is produced for a pre-determined time interval, the value of said output torque lying outside a low-load range.

Abstract: The invention relates to a method (61) for controlling a regeneration process of an exhaust gas particle filter (41) of an internal combustion engine (11), wherein said method (61) comprises safeguards (71) for protecting said exhaust gas particle filter (41) from overheating and when implementing said safeguards (71) a gas flow (ma) of the gas flowing through the exhaust gas particle filter (41) is reduced (71a, 71b) for the purpose of restricting a reaction rate of an exothermal reaction taking place in said exhaust gas particle filter (41) during the regeneration process.

Abstract: This paper suggests a procedure for the operation of an internal combustion engine, which has a particle filter arrayed to its emission system, which, during regeneration, is cleansed of its stored particles. This also describes the procedure's comparison of the engine's amount of a load to the load threshold value. It also has a throttle cut-off, which suppresses the fuel supply entirely when the engine's amount of a load is lower than the load threshold value and the engine's revolutions are higher the revolution threshold value. The set load threshold value above null is further dependant on the particle filter's regeneration signal. These procedures, based in this invention, are to prevent the overheating of the particle filter during its regeneration.

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.

A second slot connector is mounted on the mezzanine board for connecting to a second plug-in card. The first and second plug-in cards align with similarly-shaped slot access panels in the electronic system.

The host/data controller also interleaves data on a plurality of channels associated with each of the plurality of memory modules. The system implements error interrupt control, ECC error reporting, cartridge error power down procedures in response to command errors, storage of error information in unused segments of each DIMM, hot-pug procedure indicator and remote tagging capabilities of memory cartridges and DIMMs.
