Abstract
A two-stroke engine comprises a first oiling system and a second oiling system. The first oiling system includes a low-pressure pump that distributes oil from a first oil tank to the two-stroke engine. The second oiling system includes a pump mechanically coupled to a crankshaft of the two-stroke engine, wherein the pump distributes oil from a second oil tank to an accessory at a pressure greater than the first oil pressure, wherein oil distributed to the accessory is returned to the second oil tank.
Claims20
A snow vehicle comprising:
- an endless track;
- a frame;
- a transmission;
- a two-stroke engine having a crankshaft and at least one air intake port, the crankshaft defining a rotational axis and being mechanically coupled to drive the endless track via the transmission;
- a turbocharger coupled to the at least one air intake port of the two-stroke engine;
- an oil tank;
- and
- a turbocharger oil pump coupled to the oil tank and fluidically coupled to the turbocharger, wherein the turbocharger oil pump is disposed on a same side of the engine as the at least one air intake port.
A snow vehicle comprising:
- an endless track;
- a frame;
- a transmission;
- a two-stroke engine having at least one air intake port and an exhaust outlet port and a crankshaft mechanically coupled to drive the endless track via the transmission;
- and
- a pressurized oil system comprising:
- a turbocharger coupled to the at least one air intake port of the two-stroke engine, the turbocharger comprising:
- a turbine in fluidic communication with the exhaust outlet port,
- a compressor configured to provide compressed air to the at least one air intake port of the two-stroke engine,
- one or more bearing components,
- an oil inlet port,
- an oil outlet port;
- and
- a turbocharger oil pump coupled to an oil tank and fluidically coupled to the oil inlet port of the turbocharger and fluidically coupled to the oil outlet port of the turbocharger, wherein the turbocharger oil pump is disposed on a same side of the engine as the at least one air intake port of the two-stroke engine.
