Zusammenfassung:PROBLEM TO BE SOLVED: To indirectly evaluate atmospheric temperature by using an input provided to be used for an engine control module. SOLUTION: A method and a system for indirectly evaluating atmospheric temperature evaluates atmospheric temperature by filtering temperature input from a turbo charger intake opening sensor. Filtering comprises a step for compensating a temperature change in an engine isolated chamber, which changes in relation to a real atmospheric temperature. COPYRIGHT: (C)2005,JPO&NCIPI
