ABSTRACT:
In a two-stroke-cycle dual-piston engine in which a fuel mixture is compressed in the crank chamber by the reciprocating pistons, the compressed fluid flows from the crank chamber and a compartment of one cylinder open toward the crank chamber through a transfer port into a compartment of the other cylinder between the piston therein and the cylinder head, thereafter through a combustion chamber in the cylinder head into the communicating compartment of the first-mentioned cylinder, and the exhaust gases are ultimately discharged through an exhaust port, the transfer port and exhaust port being opened and closed by control devices on the pistons, the exhaust port and transfer port are both controlled by the piston in the first-mentioned cylinder in such a manner that the exhaust port is opened before the transfer port and closed after the transfer port.
