ABSTRACT:
An internal combustion engine having a pair of opposed pistons in a block has a piston connected to a respective crankshaft. A gear train synchronizes the speed and relative angular relationship between the crankshafts. A timing actuator, connected to and engaged with either of the crankshafts, permits continuous selective adjustment of the headspace between the pistons by varying parameters such as intake and exhaust port timing and air flow through the cylinder.
