    摘要: 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. In order to allow for an efficient regeneration of an exhaust gas particle filter (41) and still avoid damage to or the destruction of said exhaust gas particle filter (41) as a result of the overheating thereof, the invention is characterized in that during the regeneration process an instantaneous value (x(t)), which characterizes an instantaneous mass (x) of the soot situated in the exhaust gas particle filter (41), is ascertained, a check (67) is made as a function of the instantaneous value (x(t)) to determine whether said exhaust gas particle filter (41) is in an uncritical operating state and said safeguards (71) are suppressed in the event that the uncritical operating state is present.

    摘要: 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.

    摘要: 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.

    摘要: 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. With the procedure and the device defects as leakages in the air supply system of the combustion engine can be diagnosed and thus the regeneration of the particle filter interrupted if necessary before it can be damaged by uncontrolled air infiltrations.

    摘要: 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.
