ABSTRACT:
The invention relates to an engine including a cylinder defining a combustion chamber which receives a mixture for combustion thereof, and a piston slidably mounted therein for reciprocation between a first and a second limit position whereat the chamber defines its minimum and maximum volume, respectively. A pair of rotatably mounted parallel crankshafts are arranged equidistantly relative to the longitudinal axis of the cylinder, each having a crankarm rotatable about its respective crankshaft axis. Coupling means connect the crankshaft together for synchronising rotation thereof with the crankarm of one crankshaft having an angular advance over the crankarm of the other crankshaft. A rocker member pivotally connected to the piston for rocking movement about a pivot axis extends normal to the longitudinal axis of the cylinder, and a pair of connecting rods interconnect the rocker member and the respective crankarms of the crankshafts with each connecting rod being pivotally connected to the member. The rocker member with the connecting rods define a position control means for enabling the member to rock when the piston reaches the first position to maintain the piston substantially stationary at this position for a time sufficient permitting the crankarm of the aforesaid one crankshaft past dead-center. Substantially maximum compression is achieved in the combustion chamber during compression of the piston when it is at the first position while the crankarm of the aforesaid one crankshaft is positioned past dead-center whereupon combustion of the mixture maximum thrust is imparted to the piston.
