Another post got me curious, and I read a bit about how Digifant works. From what I read it seems that all 4 injectors fire together, which confuses me -- I would have guessed that each injector fired just as the intake stroke was starting for that cylinder. Does the fuel vapor just sort of accumulate behind the intake valve until the intake stroke for that cylinder? Surely 3/4 of the injection cycles are not "wasted" fuel?? Allan -- 1991 Vanagon GL |
