Patent number: 11994060Abstract: A high torque mechanism connected to a piston arranged within a cylinder and connected to a connecting rod for an engine may include features of a triangular link and a guide arm. The high torque mechanism may provide an upgrade to the conventional hardware with new elements that provide higher torque and thus allowing a reduction of fuel consumption versus a conventional engine of the same power. The high torque mechanism may include a triangular link, a crankshaft, and a guide arm. The connecting rod may be connected to the piston and a first joint on the triangular link. The guide arm may be connected to a second joint on the triangular link and a guide pivot point. The crankshaft may be connected to a third joint on the triangular link and a crank pivot point. The triangular link and the guide arm make the engine torque considerably higher in various crank ranges where the in-cylinder combustion pressure is high.Type: GrantFiled: May 2, 2022Date of Patent: May 28, 2024Assignee: International Engine Intellectual Property Company, LLCInventors: Andrei Makartchouk, Peirong Jia
