    摘要: An internal combustion engine has an exhaust gas turbocharger with an exhaust gas turbine and a compressor. In addition, an air-driven turbine is provided which is torsionally connected to the compressor and to which combustion air can be supplied via an adjustable shut-off element. For operation of the exhaust gas turbocharger over a wide operating spectrum, an additional duct is provided between compressor inlet and the air inlet of the air turbine, the air supply in the additional duct being adjustable by the shut-off element. In the lower load range, in the case where the required boost pressure falls below a threshold value, the additional duct is opened by means of the shut-off element and the air supply to the compressor inlet is reduced.

    摘要: An internal combustion engine with combined pressure charging has an exhaust turbocharger turbine arranged in an exhaust conduit of the internal combustion engine driving a compressor arranged in an intake conduit. A mechanically driven supercharger is arranged downstream of the compressor and is coupled continuously variably to the engine via a Fottinger speed transformer with variable-pitch guide vanes and variable speed slip. To bypass the mechanically driven supercharger, a bypass conduit is provided. A circulating-air slide is arranged in the bypass conduit for controlling the air quantity bypassing the mechanically driven supercharger. The degree of opening of the circulating-air slide and the slip of the Fottinger speed transformer are controlled as a function of operating parameters such that the charge-air pressure is adjusted to a predetermined set point value.

    摘要: A reciprocating piston is disclosed with variable compression height for internal combustion engines in particular. For structural simplification of the temperature-dependent change in the compression height of the reciprocating piston, a spring is provided which consists of a shape memory alloy and interacts with the pressure limiting valve. This permits temperature-dependent change in the compression height of the reciprocating piston exclusively by the pressure limiting valve so that structural simplification is achieved.

    摘要: The invention relates to a piston having a variable compression height and two control chambers connected to each other through a hydraulic system. In order to achieve better cold-start and warm-up behavior, an oil discharge bore from the upper control chamber into the crankcase is closed by a control slide valve in the cold operating state of the engine. The blockage of the oil discharge produces a great compression height and therefore high compression. The control slide valve is connected to an expansible element which maintains it in this closed position when the engine is cold. As the engine warms up, the expansible element, due to its thermal expansion, pushes the control slide valve out of its closed position, so that the discharge of oil can occur progressively more unthrottled with rising temperature. In the warm operating state of the engine the control slide valve clears the oil discharge duct completely, and an unobstructed discharge of oil is ensured.

    摘要: An arrangement for the control of the oil feed into a control chamber of a piston with variable compression height for internal-combustion engines comprises a control valve in the longitudinal bore of a connecting rod that is provided with a flow-through bore for the oil supply of the control chamber in the operation of the internal-combustion engine. This flow-through bore is closed as a function of the inertial forces acting in the oil feed. In order to avoid a ceasing of the oil column in the longitudinal bore, the control valve has an additional control bore that is opened only in the starting phase and via which an additional amount of oil is guided from the lubricating oil circuit of the internal-combustion engine into the control chamber, which accelerates the upward control of the piston.

    摘要: A charging device (supercharger) for internal combustion engines, having at least one turbine part. A mass stream of exhaust gas flows into this via an inflow region, from which a bypass duct branches off for bypassing the at least one turbine part. The bypass duct opens out into a turbine outlet duct at an outlet location in back of the turbine part. The bypass duct is opened or closed either by a first control element situated in the inflow region at the inlet of the bypass duct or by a second control element at the outlet of the bypass duct leading into the turbine outlet duct.
