Abstract:
An internal combustion reciprocating piston engine comprising a housing with a cylinder with a first axis, a piston in the cylinder, a cylinder head at one end of the cylinder, a combustion chamber defined by the cylinder, the piston and the piston head;a rotary torque output member journalled in the housing for rotation about a second axis that is perpendicular to the first axis;a crank pin connected to the torque output member;a unitary, L-shaped connecting rod having a first portion extending generally in the direction of the first axis and a second portion, integral to the first portion, extending generally transversely relative to the first axis, the first connecting rod portion being pivotally connected at one end thereof to the piston;a crank link having one end pivotally connected to the crank pin and the other end being pivotally connected to one end of the second connecting rod portion;an alignment member pivotally connected to the other end of the second connecting rod portion at a location on one side of the first axis and pivotally connected to a pivot member carried by the housing at the opposite side of the first axis; andmeans for adjusting the distance of the pivot member from the first axis whereby the displacement of the combustion chamber is increased and the compression ratio for the engine is increased when the piston is reciprocated in the cylinder upon rotation of the torque output member.
