I don't understand those numbers; O2 is measured to the nearest tenth percent, CO to the nearest hundredth percent, and HC and NOx in PPM. One PPM equals .0001 percent, so they chose the measuring units to not have too many zeros before or after the signficant digits.
If those numbers are the HC count they would be 41 PPM and 25 PPM.
