I was looking for information on the emissions of 2 stroke engines, I just can't get my head around the idea that my bitty little 67cc one lunger pollutes a whole lot more per mile than my fullsize chevrolet truck, which for the record has a 350 V8. (Which is 5736.5cc)
I found some info at this site: http://www.bajajusa.com/emissions.htm there they mentioned a 150cc Bajaj scooter that was a 2 stroke, and said it gave off 660-1540 pounds of hydrocarbons per 10,000 miles.
I got to thinking about those numbers, and they don't add up. Lets assume our Bajaj Chetak 150 cc scooter gets only 80 MPG. (I know someone who has one of the 2 strokers, and she gets right at 100 out of it) Assuming that, we could say it burns 1/80th gallon per mile, or about 1.2 ounces by weight per mile. That adds up to 750 pounds of gas to go 10,000 miles. So... How... are we getting 660-1540 pounds of hydrocarbons per 10k miles? That would mean that, on average, the entire mass of gasoline used is emitted in unburned hydrocarbons, so, how is the silly thing even running since you're in effect pouring the gas out on the ground?
Or, more likely... Who's math is wrong? Is this a case of panicky sky-is-falling environmentalism, or are my math skills at 1:48 post meridian (Early morning for me) not up to snuff yet?
