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. A V12 with two banks of six cylinders angled at 60°, 120° or 180° (with the latter configuration usually referred to as a flat-12) from each other has even firing with power pulses delivered twice as often per revolution as a straight-6. This allows for great refinement in a luxury car. In a racing car, the rotating parts can be made much lighter and thus more responsive, since there is no need to use counterweights on the crankshaft as is needed in a 90° V8 and less need for the inertial mass in a flywheel to smooth out the power delivery. In a large displacement, heavy-duty engine, a V12 can run slower than smaller engines, prolonging engine life

Anyone who appreciates the precision art of motor conceive should to get a boot out of this proposing from a Spanish technician entitled Patelo. Starting with hunks of aluminum, bronze and stainless iron alloy, he expended over 1200 hours conceiving, milling, rotating and drilling what he assertions is "probably" the world's least significant V12 engine. Powered by compressed air injection (0.1kg/sq cm), this little wonder brags a total displacement of 12 cubic centimeters from its twelve 11.3 mm diameter pistons and works like a charm.
