CESSNA1: I'm focusing my evaluation on back-pressure in the exhaust for a turbocharged diesel system. I determined the frequency based on the pulse of the exhaust valve opening (assuming the peak pressure pulse occurs during opening events and not closing). Considering 1 exhaust event per...
Thanks Dave. I think I posed my question incorrectly. I guess I'm looking for verification of the highest frequency of interest for a V6 running at 3300RPM. Since the V6 will incur 3 exhaust events every revolution, I've calculated 165Hz as the maximum frequency of interest. Does this sound...
I need to determine the sample frequency for measuring pressure pulsations. I have a V6 running at 3300 RPM (maximum). If this produces 165 exhaust events every revolution, how do you calculate the resolution necessary to capture all the significant data?
Thank you for your insight. I'm focusing most of my attention toward vibration due to the durability concerns/issues experienced in the past. The systems I release are closer to the manifold (i.e. upstream). I'm in SE Michigan. Any input regarding The Vibration Institute? Other postings on...
I'm a product engineer involved with exhaust systems and would like to obtain a better understanding of how to apply the fundamental theory to the practical application. I've had undergraduate and graduate courses in Mech. Vibration and yet, I'm finding it challenging to interpret and/or pull...
