Talk:Automobile emissions control
From Wikipedia, the free encyclopedia
I've noticed that "1.1 Increasing engine efficiency" is blank. If no one is willing to write paragraphs on engine efficiency, putting some links should be a good placeholder until someone writes something. Links such as:

- Linking to the ECU article is a good idea, but catalytic converters do not increase engine efficiency, so it should not go under that heading. Shawn D. 12:23, 17 October 2007 (UTC)
[edit] Two Catalytic Converters
I have a 1997 Mazda Protege which has a problem. I am pretty sure that it is a catalytic converter but does my car have two of them? I would go somewhere else to ask this question but no where on the Internet can I find any detailed information about my car -- not even the library has anything! 68.18.180.95 21:13, 5 May 2005 (UTC)
[edit] Spark optimizer
Spark optimizer- sounds like an advertisement of a commercial product to me.
[edit] High emissions
I recently bought a 2002 VW Passat, 130 BHP. it has 110,000 miles on the clock. When i "put the boot down" or when the engine is at high revs, there is a lot of black smoke (not blue), more than what normally should be emitted. I don't think the car has been chipped even though, in my opinion, its has more "go" than what a 130BHP car should. Any suggestions for high levels of black smoke? (the car averages 45mpg, fuel efficincy is good)
- It'd be more appropriate to ask that on any number of VW message boards (i.e. [1]), but black smoke indicates an over-rich mixture. As long as the plugs aren't fouling and the MPG is good, it's not a problem. Shawn D. 12:23, 17 October 2007 (UTC)
