摘要： A diesel or HHCI engine has an air intake and an exhaust for products of combustion. A pair of turbochargers receive the products of combustion in a series relationship and an exhaust aftertreatment device receive the products of combustion from the downstream turbine. A power turbine receives the output from the exhaust aftertreatment device and an EGR system of the power turbine passes a selected portion of the output to a point upstream of the upstream turbocharger compressor. A device adds fuel to the aftertreatment device to regenerate the particulate filter and the power turbine recoups the additional energy. The power turbine may be used to drive accessories or the prime output of the engine.

摘要： An internal combustion engine having an engine block for internal combustion, a high-pressure (HP) turbocharger for delivering pressurized intake air to the engine block, a low-pressure (LP) turbocharger for delivering pressurized intake air to the HP turbocharger, a turbogenerator for recovering heat energy from the exhaust gas downstream of the LP turbocharger to generate electricity, and an exhaust gas recirculation (EGR) system comprising an EGR-pump drawing exhaust gas from an EGR inlet located downstream of the turbogenerator, wherein the EGR-pump controllably delivers exhaust gas to an EGR mixer in the pressurized intake air stream at a location between the LP turbocharger and HP turbocharger. An electronic control unit (ECU) is adapted to command the EGR-pump to deliver a desired EGR flow-rate to the engine block based on look-up tables and either open-loop and/or closed-loop control algorithms.

摘要： An internal combustion engine has a cylinder head, a cylinder block and a cylinder liner mounted in a bore in the block. The liner has a hollow cylindrical body and an annular sealing collar projecting radially outwardly from the body. The collar a sealing surface which faces generally towards the cylinder head. A cylinder head gasket the collar sealing surface and a corresponding head sealing surface on the cylinder head to preventing combustion gasses from escaping from the piston bore. The collar sealing surface is frustoconical and extends uniformly from a radially inner edge to a radially outer edge, the radially inner edge being farther from the outer sealing surface and the radially outer edge being closer to the other sealing surface. The frustoconical sealing surface resists radial expansion of the gasket and produces a wedging action which increases the sealing engagement of the gasket with the head and collar sealing surfaces as the gasket expands radially.

摘要： A work machine having an internal combustion engine such as a diesel is connected to a transmission by a flexible coupling. The engine may have a turbocharger to increase its output. A power turbine is connected to receive exhaust products from the turbocharger turbine via an exhaust aftertreatment device. The power turbine is connected to either the transmission downstream of the flexible coupling or to an external load. In either case, the power turbine in the form of a centripetal turbine is isolated from the torsional vibrations of the IC engine.
