The internal combustion engine is a heat engine in which the
burning of a fuel occurs in a confined space called a combustion chamber. This
exothermic reaction of a fuel with an oxidizer creates gases of high temperature
and pressure, which are permitted to expand. The defining feature of an internal
combustion engine is that useful work is performed by the expanding hot gases
acting directly to cause movement, for example by acting on pistons, rotors,
or even by pressing on and moving the entire engine itself.
can remove and repair engines as well as customize them to the customer's specifications.
