    Abstract: A power system includes an engine including an exhaust line, a turbine in the exhaust line, a bypass line connected to the exhaust line upstream of the turbine and comprising a controllable bypass valve, and a controller arranged to control opening of the bypass valve to bypass the turbine when, for example, the engine is operated such that power is transmitted from the crankshaft to the turbine shaft, and/or at least one of an engine load, an engine speed, and an exhaust line pressure are below predetermined levels. A method of operating a power system is also disclosed.

    Abstract: Disclosed is a power system having a turbocharger, a VG turbocompound turbine, and a controller. The turbocharger has a turbine coupled to a compressor, and the VG turbocompound turbine positioned downstream of the turbine relative to a direction of a flow of an exhaust gas flowing through the turbine and the VG turbocompound turbine. The controller sends a signal to adjust a geometry of the VG turbocompound turbine so as to adjust a boost level being provided by the turbocharger.

    Abstract: A turbocompound unit includes a bearing housing and a turbine shaft being rotatably supported in the bearing housing, wherein one end of the turbine shaft is provided with a turbine wheel. The turbocompound unit further includes a diffuser duct in which the turbine wheel is arranged to rotate, an exhaust collector extending from the diffuser duct to an exhaust outlet, and a sealing arrangement positioned in the vicinity of the turbine wheel fir preventing oil from escaping from the bearing housing to the diffuser duct. The exhaust collector forms part of a butler gas duct that is arranged to supply exhaust gas from the exhaust collector to the sealing arrangement for pressurizing the sealing arrangement.

    Abstract: A four-cycle internal combustion engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of intake air to the combustion cylinders to be tightly controlled, so that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the air/fuel mixture auto-ignition threshold. The minimal threshold pressure of air intake is determined to be >1.8 Bars at sea level and a minimal temperature drop of at least 50° C. at the heat exchanger air cooling radiator. Because this design can effectively regulate and set the maximum pre-ignition temperature of the fuel-air mixture, it can combust virtually any type of liquid hydrocarbon fuel without knocking. This four-cycle engine, due to its higher compression ratio, generates power equivalent to or greater than a standard four-cycle engine in a smaller and lighter engine and at a higher efficiency.
