Diagnosing proper operability of a cylinder charge motion control device |
摘要 |
A method for detecting improper operation of a charge motion control device (CMC) based on exhaust temperature is disclosed. It has been found that when the charge motion control device is switched between two positions, the exhaust temperature changes by as much as 100 degrees C. The expected exhaust temperature, based on commanded charge motion control device position and current engine operating condition, and the measured exhaust temperature are compared to determine whether the charge motion control device has failed to attain the desired position.
