    Engine types

    can anyone explain to me the difference between a boxer engine and a flat engine...(as in the 911's flat 6)?

    a 911 is a boxer engine. A flat engine is a 180 degree V engine, which runs in a "normal" firing order. In a boxer engine the firing order is such that opposite pistons move towards each other, hence it appears that the pistons are "boxing". (but they never hit)

    a good example of this would be at http://auto.howstuffworks.com/
    thats a VERY good site for learning that kind of stuff.

    the firing order isnt as big an influence as the arrangement of the pistons, an inline engine would still run firing 1234 instead of 1324 or 1432 or wutever

    but it wouldnt if it was --_ _ instead of _--_
