Publication number: 20250092815Abstract: An engine is disclosed having a water cooling system allowing efficient cooling of the exhaust valves to prevent temperature gradients from building in the engine. Water is therefore pumped through the engine though first and second water cooling cores which discharge through the head. A water manifold is positioned over the discharge opening and includes couplings for the radiator supply, radiator return, water pump supply, oil cooler supply and oil cooler return. The engine has separate chambers to isolate the pistons and cylinders, and reed valves cover the chambers and allow the blow-by gases and oil to enter the oil pan during the power stroke of the engine cycle.Type: ApplicationFiled: December 3, 2024Publication date: March 20, 2025Inventors: Daniel J. Nugteren, Alexander W. Oppermann, C. Scott Walter, G. Jay McKoskey, Jeffrey M. Maher, Steven M. Tittl

Patent number: 11815037Abstract: A method and system for operating a two-stroke engine includes a fuel system comprising a fuel pressure sensor, fuel temperature sensor and a fuel injector and a controller in communication with the fuel pressure sensor and fuel temperature sensor. The controller controls the fuel injector with a fuel pulsewidth determined by determining a beginning time of a window for measuring fuel pressure, determining an ending time of the window, measuring fuel pressure between the beginning time and the ending time, determining a fuel pulsewidth based on the fuel pressure and fuel temperature and injecting fuel into the two-stroke engine in response to a desired fuel mass.Type: GrantFiled: July 21, 2022Date of Patent: November 14, 2023Assignee: Polaris Industries Inc.Inventors: James H.

Patent number: 10247148Abstract: An internal combustion engine includes a crankcase including a crankshaft and at least one cylinder coupled to the crankcase. The at least one cylinder has an intake port and defines an internal combustion chamber. The engine further includes a throttle body assembly with a throttle valve coupled to the intake port of the at least one cylinder and a throttle plate. Additionally, the engine includes a supplementary air inlet fluidly coupled to the intake port and spaced apart from the throttle valve. The supplementary air inlet is configured to receive a flow of air from a location downstream of the throttle plate when the throttle plate is in a fully closed position and the flow of air is directed into the combustion chamber through the intake port for combustion therein.Type: GrantFiled: March 7, 2016Date of Patent: April 2, 2019Assignee: Polaris Industries Inc.Inventor: G.
