The function of an O2 sensor in your car is to measure "raw" oxygen, as in "O2" as it's suspended in the atmosphere. Typically it works as a heated element. As it "burns" the oxygen going by, it generates a signal back to your car's computer, which is in turn converted into a "level" reading. With MTBE and oxygenated gases, the "oxygenation" is part of a larger molecule - it is not a free diatomic. As a result, your oxygen sensor won't be reading it. It CAN"T read it based upon the way the O2 sensors works - it is, in essence, a secondary combustion reaction. From what I've gathered from (what little) I've actually read about MTBE, the IDEA behind it is that by having the chemicals infused into the gasoline, they are able to reduce CO, NOx, and other chemicals. This *can* be as simple though as turning CO into CO2. They don't tell you if CO2 is increased, decreased, or static. I've been hunting trying to find a chemical equation which actually shows the combustion reaction of Gasoline w/ MTBE in it. No avail so far. Still searchign through the scientific journals. But in the end, Oxygen as it is part of a GREATER molecule does not affect the O2 sensor of your car. If this is the case, CO and CO2 (standard products of combustion) would ALSO effect the sensor. --John To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
