CHEVROLET ISUZU NHR REWARD 2022 Euro IV - Diesel Engine 4JH1-TCN - 2999 cc

Post by BrayanArangoG » Wed May 14, 2025 2:26 am

Dear forum moderators, as I mentioned in my first post, in this second post I am sharing the pressure signals (channel A) and fuel injection signals (channel B) taken from the ISUZU 4JH1-TCN diesel engine. I would greatly appreciate it if you could convert the .psdata files to .mwf format for further analysis in the USB OSCILLOSCOPE software.

I hope that with these new measurements or with your help, I will be able to run the script correctly this time.

I appreciate any guidance you can provide on how to configure the options menu when executing the script in the USB OSCILLOSCOPE software, as I have confirmed that neither the sensor (WPS500X) nor the connection are defective after repeating the tests. Thank you once again for your time and assistance.

Sincerely,
Brayan Arango González — Mechanical Engineering Student, UdeA

You can familiarize yourself with the capabilities of the Px script, which is designed for analyzing the pressure graph in the cylinder of gasoline engines:
