Embodiment Construction

[0020] figure 1An internal combustion engine 1 is shown. In the embodiment shown here, the internal combustion engine has four cylinders 2 . Each cylinder 2 is connected to an exhaust manifold 4 via an exhaust manifold 3 . In this case, the exhaust gas trap 3 and the exhaust gas manifold 4 form an exhaust gas system (Abgastrakt) 5 . In addition, an exhaust gas cleaning device 6 , not shown in detail here, such as a particle filter, is also arranged in this exhaust system 5 . In this case, each cylinder 2 of the internal combustion engine 1 contains a reaction space 7 . In this case this reaction space can also be called a combustion chamber. A further reaction space 8 is assigned to the exhaust gas purification device 6 . The fuel fed into the exhaust gas of the internal combustion engine reacts in this reaction space. In this case, the reaction space 8 is arranged, for example, flow-technically upstream of the particle filter of the internal combustion engine 1 . This ...

Abstract

The invention relates to an operation method of an internal combustion engine (1), wherein, the internal combustion engine (1) comprises at least one reaction space (7,8) with the temperature and / pr exhaust temperature of the reaction space set. It is specified that the reaction space (7,8) is provided with a temperature sensor (14) for measuring the resistance (13) and related with the temperature. The temperature sensor is applied for determining a measured value corresponding to the sensor temperature and further determining the reaction space temperature and / or the exhaust temperature of the internal combustion engine by means of a temperature model (15) with a measured value as an input value (16). Furthermore, the invention relates to a device for the operation of the internal combustion engine, a computer program and a computer program product.

Description

technical field [0001] The invention relates to a method for operating an internal combustion engine, wherein the internal combustion engine has at least one reaction space and the reaction space temperature and / or the exhaust gas temperature is determined. Furthermore, the invention relates to a device for operating an internal combustion engine, a computer program and a computer program product. Background technique [0002] The prior art discloses methods of the type mentioned at the outset. For example, an internal combustion engine has a reaction chamber and / or an exhaust gas system. It is also known to assign an exhaust gas turbocharger to an internal combustion engine in order to increase its efficiency or its power. To control and / or regulate the internal combustion engine it is necessary to know the temperature in the reaction space and / or the temperature upstream of or in the exhaust gas turbocharger. Using this temperature value, the internal combustion engine ...
