Hi guys,
In my quest to know more I've been buffing up about anti lag. And I've soon discovered that 90% of people don't have a clue what it is, and the other 10% can't explain it very well.
I'd just like to clarify that anti lag basically retards the ignition of an engine to the point where maximum cylinder pressure occurs very late in the compression stroke so that the engine maintains high exhaust pressures and temperatures while keeping the torque on the crankshaft low. This means the turbo is kept spinning between shifts etc.
What I don't get is then they talk about a bypass valve system from the turbo's compressor which feeds air during anti lag operation to the exhaust system so the fuel can combust??? I'm getting confused... is this another type of anti lag system where unburnt fuel is introduced to the exhaust system and picks up so much latent heat from the pipes and turbo it ignites causting a pressure rise? Can someone help me out? :blink:
