Patent number: 10731620Abstract: A system for starting an engine of a vehicle has a fuel injector injecting fuel into a closed intake port to form an air fuel mixture. The system also includes an actuator rotating a crankshaft in a first direction to open the intake port by moving a piston within a cylinder coupled to the crankshaft. A combustion chamber defines between the cylinder and the port receiving the air fuel mixture through the intake port. The actuator rotates the crankshaft in a second direction to close the intake port. A spark plug ignites the air fuel mixture to start the engine. The engine also includes many other disclosed features.Type: GrantFiled: September 28, 2018Date of Patent: August 4, 2020Assignee: Polaris Industries Inc.Inventors: Dallas J. Blake, James A. Barczak, Lawrence J. Hosaluk, Darren J. Hedlund, Oliver J. Young, Matthew D. Reeves, Joseph D. Tharaldson, Chad A. Dale, Stephen G. Crain, Trevor F. Rhodes

Patent number: 10648399Abstract: A two cycle engine having a block defining an exhaust port and a cylinder, a head, and a piston defining a combustion chamber is disclosed. The exhaust port has a resonant frequency that causes a portion of the combusted and uncombusted exhaust gasses to flow from the exhaust system and back into the combustion chamber. At a speed above the predetermined speed, a majority of the portion of the combusted and uncombusted exhaust gasses flows from the exhaust system and back into the combustion chamber without engaging the skirt of the piston.Type: GrantFiled: October 3, 2017Date of Patent: May 12, 2020Assignee: Polaris Industries Inc.Inventors: James A Barczak, Lawrence J. Hosaluk, Dallas J. Blake, Darren J. Hedlund
