4-gas results
not at all what I expected to see...
CO2 = carbon dioxide
CO = carbon monoxide
HC = hydrocarbons
O2= oxygen
at idle
CO2- 2.7% CO- .02%
HC- 6ppm O2- 0%
Low Cruise - 1500 rpm
CO2- 2.5% CO- .03%
HC- 5ppm O2- .13%
High Cruise - 2000 rpm
CO2- 2.64% CO- .03%
HC- 5ppm O2- .13%
4" puddle of CRC C111C on the floor, wand 4" above
CO2- .02% CO- 0%
HC- 93ppm O2- .13%
I really expected to see more oxygen in the tailpipe, especially at idle.
If this was a gas engine, I'd say it's running pretty darn well.
(note: this truck was built w/o a catalytic convertor)
