Re: Understanding emission numbers and how they work



Cool. I went through the same thing. Though here in DC we have emissions
tests, the dealer I work for doesn't have a dyno. And since I probably
used our gas analyzer 3 or 4 times in 5 years, practical emission
experience has always been hard to come by. I passed it doing the same
thing as you; buy a couple of books and hunker down for a few months.
I was suprised how general a lot of the test was. There were plenty of
questions involving the interpretation of tailpipe readings, but there
were a lot of questions in which I had to draw on things I remembered from
the other A-series tests. I thought it was real thorough, much more so than
any of the others. Good luck.
