V-8 when applied to engines refers to the fact that the engine
has eight cylinders
that are arranged
in the form of a "V" when looked at from the front
. So, cylinder 1 slopes
up at an angle
to the left, cylinder 2 at an angle to the right, and so forth.
One of the advantages
of such an arrangement
is that the engine runs a lot smoother
than engines with all the cylinders arranged in line.
produced by a V-8 engine is unmistakable
Engines with more or fewer cylinders arranged in a V are found too. In Formula 1 racing, for example, nearly all cars have V-10 engines.
