If
a certain fixed quantity of air-or anyother gas- is confined in a
closed container and then heated, the
pressure inside the
container will rise. If one of the walls of the
container is moveable, the internal pressure will push that wall
outward with a certain
amount of force, according to
how much heat was put into the trapped
gas. That, in a
nutshell, is the working principle of all internal combustion
engines: Each cylinder is a
closed container, and each piston represents a moveable wall of
that container; the heat is supplied by the burning
of a fuel,
usually gasoline, and the trapped
gas is whatever
mixture of gaseous compounds left over
after the burning.Meanwhile, the other moving parts of
an engine are
there for one or the other of just
two supporting functions. The "bottom
end" converts the
movement of the pistons into rotary motion
and, by returning them to the top of their
strokes, restores the closed containers to their original size; the
valve gear and everything
else at the "top end" are there simply to
provide for the emptying out of the spent
gasses and the refilling of the cylinders with
a fresh charge of burnable mixture.
This may all seem very obvious to
anyone with even the
most basic understanding of how engines
work, but lurking within the simple facts
outlined above is a wealth of detail.
Consider the fuel, for example.
Some fuels
contain more chemical energy per pound than
others, and so can produce more heat when
burned. Even limiting the discussion to gasoline, the fact is that
ordinary pump gasoline
is a mixture of hundreds of different
flammable compounds, and each of those
compounds has a different potential ability to
generate heat when burned. The exact nature
of the mixture of these compounds varies from one pump to another
and from one
season to the next, so a pound of gasoline from
one pump on one day might release
somewhat more or less heat when burned than
would a pound from another pump, or from
the same pump on some other
day.
