  • Publication number: 20110041498
    Abstract: An exhaust gas system configured for an internal combustion engine includes a cylinder head having at least two cylinders, a single exhaust duct emerging from the cylinder head, an individual exhaust duct provided between each cylinder and the single exhaust duct, and a reservoir of fixed volume integrated in the cylinder head and coupled to the single exhaust duct via a connecting duct. A reservoir valve is provided in the connecting duct in some embodiments. According to one embodiment, a method is disclosed in which the reservoir valve is commanded to an open position when flow through the single exhaust duct is large and commanded to a closed position when flowrate through the single exhaust duct is small. In some embodiments, a turbine, with a selectable volume upstream of the impeller, is coupled to the cylinder head.

  • Patent number: 4677826
    Abstract: Several embodiments of turbo-charged two cycle internal combustion engines utilized in combination with an outboard motor. In each embodiment, the exhaust system for the engine includes devices for insuring that sufficient backpressure is exerted at the exhaust port of one cylinder during the overlap period when its scavenge passages and exhaust ports are both open so as to preclude the discharge of fresh fuel/air mixture to the atmosphere without adversely affecting the turbo-charger performance. In some embodiments of the invention, a valve arrangement is controlled for controlling the proportion of the exhaust gases that flow across the turbo-charger so that at some running conditions, the turbo-charger receives all of the exhaust gases. In all embodiments, an expansion chamber device is incorporated in the drive shaft housing of the outboard motor and in some embodiments, the turbo-charger turbine inlet receives its gases from this expansion chamber.
