hydrogen into 240?

    a friend and I are looking to experiment with an electrolysis cell to
    produce Brown's gas (hydrogen and oxygen together), to be fed into an
    automobile engine. We were thinking of using my '89 volvo 240, which is
    fuel-injected. The question I have is, should I feed the gas in AHEAD of the
    air mass meter, or AFTER it (into the intake manifold, for example).... I
    can think of good and bad arguments for both, so am wondering what
    experience anyone else has had....

    Study propane installations.

    Post throttlevalve is more complicated due to manifold vacuum. Before or
    after the AMM doesn't matter much, a backfire goes all the way ;) (but
    hydrogen bangs are not very powerfull) Note where the extra air for
    cold idle is coming from, this has to be routed post fuel inlet, to
    avoid leaning out with pure air during warmup.

  3. If you are talking about a stoichiometric mixture of hydrogen and oxygen (so
    that it could burn without added air) you definitely want to go between the
    AMM and the engine. The AMM says how much fuel to add for the amount of air
    coming in, so it would run too rich if the "air" were actually another
    fuel/air mixture.

    You'll probably want an arrangement similar to an LP gas installation.
    Those normally shut off the injection system when you want to run on LP
    and use a special carburetor for the LP gas.
