High Quality Content by WIKIPEDIA articles! The Packard 1A-1500 was an American 12 cylinder liquid-cooled 60 degree Vee piston aircraft engine designed in 1924. Test flown in the second prototype Douglas XO-2 it proved to be unreliable, there were 29 built.A V12 engine is a V engine with 12 cylinders mounted on the crankcase in two banks of six cylinders, usually but not always at a 60° angle to each other, with all 12 pistons driving a common crankshaft.Since each cylinder bank is essentially a straight-6, this configuration has perfect primary and secondary balance no matter which V angle is used and therefore needs no balance shafts.
