Abstract

This paper studied a noise problem of turbocharger engine, which results from activation of the dump valve. Lots of vehicle tests have been done to find out that this noise problem always occurs when quickly release the throttle pedal at the end of acceleration. At this condition, EMS opens the dump valve and the turbocharger pressure arises quickly, which results in the noise. After analyzing the control parameters and test data in detail, the control parameters of dump valve duty cycle at transient process and the dump valve opening timing were optimized by calibration. Through EMS calibration, assisted with mechanical optimization, the test results show that the waste gas pressure was reduced by 60 hbar at least, and the noise problem was solved successfully.
