Ok, here goes....
They do two "dyno pulls", one at 15mph and the other at 25mph.
The Acura is front wheel drive, automatic 5 speed trans, 3.2 litre V6.
The Chevy Silverado truck is rear wheel drive, manual 5 speed trans, 6.0 litre V8.
Acura:
%CO2 - 14.8 - both runs
%O2 - 0 - both runs - (i guess that's closed loop on the O2 sensors)
HC (PPM) - hydrocarbons
6 (above average) - 15mph
2 (below average) - 25mph
CO % - carbon monoxide
0 (below average) - 15 mph
0.01 (same as average) - 25 mph
NO (PPM) - Nitrous Oxide
10 - (Average is 16) - 15mph
10 - (Average is 18) - 25mph
So the Acura passed the test with flying colors.
Chevy Silverado:
%CO2:
6.85 - 15mph
6.79 - 25mph
%O2:
11.09 - 15mph
11.24 - 25mph
HC and CO:
All Zero - both runs
NO (PPM) - Nitrous Oxide
8 - 15mph
4 - 25mph
So the Chevy beats the ULEV Acura into the weeds on emissions testing at the local test station. But, then again, the test equipment was running on Windows 95, and the damn thing crapped out twice during the Chevy test. So who knows?
Not sure why the Chevy pushed out more O2, better lean burn setup perhaps? It also pushed a lot of H20 out of the tail pipe.
You may think that I have over analysed all this, but hey the tests cost $60.20 each, so why not get my money's worth :)
