This test was taken at 15mph with CA’s best 5 Gas-Analyzer
The paper reads:
1. HC ppm (Wasted Fuel) 1ppm *Yes, just ONE!
2. NO ppm (Nitric Oxide) 23ppm *Only when this number is over 100 it will do harm to us. This number is lower than indoor propane forklifts!
3. CO (Carbon Monoxide) 0.02% *Need I say more?!
4. CO2 (Carbon Dioxide) 14.4% *1,000ppm is considered “Acceptable”, but will do no harm to us unless over 25. This number is well below that!
5. O2 (Oxygen). 0.9%
I also just gained another 15 miles to the tank! Now at 455 miles to empty. Check it out!
here's how I read these results -
1. 1ppm is probably instrumentation error...for all intents and purposes, this indicates
complete combustion.
2. Combustion temps are in the correct range to produce a minimum of NOx
3. 0.02% Carbon monoxide is, like the HC reading, within the range of instrumentation error of the machine performing the readings - none is being produced
4. CO2 is 14.4% of what? if that's of the 1000ppm "acceptable" reading to pass CARB,
this engine is 85.6% below what they consider low enough.
5. 0.9% Oxygen in the exhaust jives with the HC 1ppm reading in #1, so again,
all the oxygen is being used and combustion of the fuel is complete.
Michael - congrats on a fantastic showcase vehicle. This proves that the groove does indeed work in conjunction with existing systems.
Now - if you'd like to try and take it just a wee bit (or maybe more) farther, I'd put a MAP enhancer on and an EFIE on the O2 sensors to see if you can >500 miles out of a tank
