gibvel Posted October 3, 2007 Share #2 Posted October 3, 2007 It's an Air Injection System. According to Freebird in this post on "Plugging the AIS": http://www.venturerider.org/forum/showthread.php?t=485 The AIS is an emissions system which introduces oxygen-bearing air into the exhaust ports on the exhaust stroke. This induces further combustion of hydrocarbons in the exhaust pipe and greatly reduces emissions. It is driven by intake vacuum pulses. Link to comment Share on other sites More sharing options...
Eck Posted October 3, 2007 Share #3 Posted October 3, 2007 My understanding of it best I can explain is... An Air Induction (or injection) system forces fresh air (Oxygen) into the exhaust system to reduce emissions The exhaust gases can contain unburned fuel. Oxygen from the air injection system causes this fuel to continue to burn reducing omissions. The AIS system is required in California... Gibble, you beat me to it... I was typeing at the same time you were... Link to comment Share on other sites More sharing options...
