Determining internal combustion engine gas outlet or inlet temperature involves engine-specific model depending on temperature in combustion chamber for defined crankshaft position

摘要

The method involves determining the temperature profile within the combustion chamber depending on the position of the crankshaft. The internal combustion engine gas outlet temperature is derived with the aid of an engine-specific model depending on the temperature detected in the combustion chamber for a defined crankshaft position. AN Independent claim is also included for the following: an arrangement for determining gas outlet or inlet temperature for internal combustion engine.
