| description | A dynamic wastegate failure detection apparatus for determining wastegate failure levels for individual internal combustion engines is disclosed. The apparatus repeatedly measures and stores intake boost pressures at times when the engine is producing higher boost pressure levels. The apparatus calculates a boost pressure limit value as a function of the stored boost pressures. A wastegate failure is indicated and the engine output power is derated when a boost pressure value exceeds the sum of the boost pressure limit value and a predetermined pressure differential. |
