A system for a vehicle has an oil supply, an engine oil pump comprising a plurality of ports and an engine coupled to the plurality of ports. A turbocharger is coupled to the engine. A turbocharger oil pump is coupled to the oil supply comprising a first port coupled to the turbocharger.

Turbocharger lubrication system for a two-stroke engine

A system and method of controlling a turbocharged engine system includes receiving a boost mode selection signal and controlling the turbocharged engine system in response to the boost mode selection signal.

Turbocharger system for a two-stroke engine having selectable boost modes

A method and system for controlling operation of a two-stroke engine having a turbocharger includes the two-stroke engine comprising an electronically controlled exhaust valve. A throttle position sensor generates a throttle position signal corresponding to a position of a throttle plate of a throttle. A boost box is coupled to the two-stroke engine. A boost box pressure sensor is coupled to the boost box and generates a boost box pressure signal corresponding to a pressure within the boost box. A controller is coupled to the boost box pressure signal controlling a position of the electronically controlled exhaust valve in response to the boost box pressure signal and the throttle position signal.

System and method for controlling operation of a two-stroke engine having a turbocharger

An engine is disclosed having a starter clutch ring gear, and a crank case having an integral starter pinion accepting member defining a through bore, and a gear assembly having an exterior surface configured to engage a flywheel and an surface engaging the second of the shaft. A starter pinion shaft is disposed through the through bore. The integral starter pinion accepting member defines a surface coupled to an engine mount.

Crankcase mounts and reinforced rubber in mount on force vector

An exhaust system for a vehicle including a deep snow exhaust outlet defined by a driveline structural member of the vehicle. If the vehicle includes a turbo charger and an exhaust silencer, the turbocharger and the exhaust silencer are coupled together without exhaust piping therebetween.

Exhaust system for a vehicle

A power generation system is provided including a power boost regulator operative to provide load matched voltage operation of an AC power source.

Power boost regulator

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.
