Few days back I have been to Shell fuel station at Expo road Johar town Lahore where I saw ENERCON DIAGNOSTIC TUNE UP CENTRE. Upon inquiring whats these are all about the tests they perform. They offer a free test for my cuore.
What they did, place some pipe like sensor in the exshuast pipe and rev the engine constantly like for 1 min and gave me the test report which have few gases and its quantity which are as:
For Petrol
1-CO 002.76 %Vol
2-HC 101.00 PPM
3-NO 195.00 PPM
3-NOx 214.00 PPM
4-O2 - 003.2 %vol
5-CO2 011.3 %vol
For CNG
1-CO 000.14 %Vol
2-HC 038.00 PPM
3-NO 148.00 PPM
3-NOx 162.00 PPM
4-O2 - 003.20 %vol
5-CO2 009.80 %vol
I just wanted to know what does these value indicate. Although the guy did not know about what these are indicating with respect to engine performance and setting. Although he said your combustion is good.
ppl need your expert opinion on this.
My apology if I have dare to creat a duplicate thread as I could not find one alik;)
