My 328i touring has an LPG system fitted,
but its an old skool "single point" mixer system, feeding the LPG into the inlet tubing behind the MAF.
This then passes through the throttle body and into the inlet manifold.
It occurred to me today that the engine is essentially functioning like a carb fed engine whilst on LPG, and that my usual practice of using DFCO for approaching junctions etc would mean that the engine is just pulling in LPG but not getting the "work " out it?!
so am I better just using the brakes to slow at junctions, after coasting as far as possible?
your thoughts please
