Thanks James - I take your point. Having run a V70 LPG conversion very happily for over 250,000 miles it always intrigued me as to how it was possible to get the car to run on a fuel that it wasn't designed for without doing damage.
My car had the Fenix engine management system - don't know how much that would affect your thinking. The O2 sensor died and was replaced with a new Volvo one at around 140,000 miles, and the car would throw lights and codes at around the 250,000 mile mark, but a new LPG vapouriser and injector nozzles resolved that.
Apart from that the only real LPG-related attention mine ever had was new plugs every 10k, and a new LPG filter every 15k.
So in an LPG set up where the fuel pressure is fixed, presumably the way in which more fuel is supplied in response to the driver's right foot is simply by opening the injector solenoids at a faster rate? Each time they open they'll presumably pass a fixed amount of gas?
Great insight - thanks
Jack
