Abstract:
1. A dual link internal combustion engine comprising: a cylinder block defining a cylinder; a piston slidably disposed in the cylinder; a crankshaft rotatably mounted with respect to the cylinder block; an exhaust valve; an intake valve; a plurality of links coupling a piston pin of the piston to a crank pin of the crankshaft to reciprocate the piston in the cylinder as the crankshaft rotates, the plurality of links including a first link coupled at a first end to the piston pin and a second link coupled to a second end of the first link; and a combustion chamber having a pent roof with angled wall surfaces of generally conical shape with a peak of the pent roof being a meeting of the angled wall surfaces and being positioned to one side of a piston reciprocation line without intersecting the piston reciprocation line, the exhaust valve being disposed on a combustion chamber wall surface to the left side of the piston reciprocation line and the intake valve being disposed on the combustion chamber wall surface to a right side of the piston reciprocation line, as viewed in a crank axial direction where a piston top dead center is at a top and a piston bottom dead center is at a bottom as the crankshaft rotates clockwise, the piston, the piston pin and the first and second links having a following relative configuration in which
