    v6 is the configuration of the cylinders. i.e. two banks of 3 cylinders.

    3.2L is the engine capacity. That is the total volume of the cylinders. 3.2L is 3.2 Litres, so each cylinder is 1 sixth of 3.2L (because there are 6 cylinders).

    DOHC is Double Over Head Cams.

    MFI i'm not sure, I imagine that would be Multi point Fuel Injection. That would mean there is more than one fuel injector per cylinder.

    LY9 looks like it's just a model number.

    3.2L is the engine size, and MFI i think is multiport fuel injection and DOHC is dual overhead cam meaning that both sides of the engine has a camshaft

    In the common parlance, MPI and MFI are actually two different ways of referring to the same system. MPI breaks down as "multipoint injection," and MFI stands for "multipoint fuel injection." You could also abbreviate the latter as MPFI, MI or Fi. BMW originally dropped all but the last letter when referring to the same system and still uses the old "-i" suffix in spite of the fact that the company no longer manufactures a car without fuel injection.
