An internal combustion engine comprising a combustion chamber having at least two rigidly fixed inner wall surfaces and at least three movable inner wall surfaces reciprocally mounted and adapted to reciprocate from a first position lessening the internal volume of the combustion chamber to a second position expanding the internal volume of the combustion chamber. The reciprocal linear movements of the movable, inner wall surfaces are operatively coupled to a crankshaft. A spark plug is secured in the combustion chamber and has the spark gap terminals thereof extending into the combustion chamber. A pair of inlet and exhaust valves disposed in the combustion chamber and opening inwardly thereunto complete the major components of the novel engine.
