Abstract: A snowmobile includes a forward frame assembly defining an engine bay. An engine is positioned within the engine bay. The engine has a plurality of intake ports positioned on an aft side of the engine and a plurality of exhaust ports positioned on a forward side of the engine. An air intake system has at least one air inlet and a plurality of air outlets. The air intake system is coupled to the aft side of the engine such that each of the air outlets is configured to provide air to one of the intake ports. An exhaust system has a plurality of exhaust inlets and at least one exhaust outlet. The exhaust system is coupled to the forward side of the engine such that each of the exhaust inlets is configured to receive exhaust from one of the exhaust ports.

Abstract: Embodiments describe a method of controlling a two-stroke internal combustion engine is shown. The method includes selecting one set of two or more sets of engine parameter inputs or a weighted value of two or more sets of engine parameter inputs, determining an engine output parameter from the selection, and utilizing the determined engine output parameter to control one or more engine operations; re-selecting one set of two or more sets of engine parameter inputs or a weighted value of two or more sets of engine parameter inputs during engine operation, utilizing the reselected output parameters to adjust one or more engine operations. Each set of engine parameter inputs includes a direct measurement of crankcase pressure and engine speed and optionally one or more of barometric pressure, exhaust valve position, air temperature, engine coolant temperature, exhaust temperature, boost pressure, crankshaft position and direction of rotation, humidity, fuel pressure, fuel temperature, detonation sensor level, exhaust oxygen content, and throttle valve angle.

Abstract: A snowmobile includes a frame, at least one ski, handbars operatively coupled to the at least one ski, and an engine assembly comprising an engine and an exhaust manifold. The exhaust manifold includes at least a first inlet, a first outlet, and a second outlet. The first inlet is configured to connect to a first exhaust port. The first outlet is connected to provide exhaust received from the first inlet to a first exhaust path and the second outlet is connected to provide exhaust received from the first inlet to a second exhaust path.

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.
