The invention relates to an internal combustion engine having a turbocompound system. The turbocompound system encompasses an exhaust-gas turbocharger, a turbo intercooler, and a power turbine. The power turbine is connectable, via a transmission with clutch, to the crankshaft of the internal combustion engine. A connectable compressor, which is couplable either to the power turbine or to the internal combustion engine, is received in a multiple-flow intake pipe.

Compound turbocharger system having a connectable compressor

In a charging device for an internal combustion engine, the charging device has at least one first line for the intake of fresh air, having at least one air-gap-insulated exhaust-carrying component. This is assigned to an outlet side of the internal combustion engine. At least one regulating element for distributing an exhaust gas stream, and at least one regulating element for distributing a pre-compressed fresh air stream is provided. The air-gap insulated exhaust-carrying component has an outer chamber, through which a controllable stream of fresh air flows.

Charging device with exhaust gas temperature control device

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.

Flow-optimized bypass for turbo engines

In an air compressor, particularly for an internal combustion engine, which has a compressor housing with a flow duct structure and a recirculation arrangement including a bypass structure for recirculation some of the air entering the compressor wheel, a recirculating ring is arranged in the bypass flow structure around the compressor wheel and the ring has a plurality of flow passages distributed uniformly around its circumference with inflow orifices at the radial inner end in communication with the compressor flow duct and outflow orifice at the radial outer end in communication with a by-pass flow space.

Compressor, in particular for an internal combustion engine

In a process and apparatus for two-stage supercharging of process air for a fuel cell, in one of the two charging stages, supercharging taking place by means of a displacement machine. In the other charging stage, supercharging is performed by means of a combined expansion and compression machine. Energy is recovered from the exhaust gas of a fuel cell by means of the combined expansion and compression machine.

An exhaust gas turbocharger for an internal combustion engine includes an exhaust gas turbine in the exhaust gas system and a compressor in the intake system for producing compressed charge air. A compressor rotor is arranged in a compressor inlet channel. In order to achieve a greater range of utilization, an adjustable shutoff element is arranged in the compressor inlet channel, upstream from the compressor rotor, for variable adjustment of the effective cross-section.

In an exhaust gas turbocharger for an internal combustion engine, in which a compressor is disposed in the intake duct and a turbine is disposed in the exhaust duct, and wherein the turbine has a turbine wheel in a turbine housing with at least one inlet flow passage for the introduction of exhaust gas which flow passage is provided with a variable turbine geometry for the variable setting of the effective turbine inlet flow passage cross-section, the variable turbine geometry being adjustable between a shut-off position that minimizes the turbine inlet flow cross-section and an open position that maximizes the turbine inlet flow cross-section, a gas-collecting chamber is provided which is in communication with the inlet flow passage in the turbine housing, the total volume of flow passage and the gas-collecting chamber being adjustable by an actuator movably disposed in the turbine housing as a function of the operating state of the internal combustion engine.

A method for operating a reciprocating-piston internal combustion engine, having an injector nozzle operable by a single valve element and configured to directly inject a fuel into a combustion chamber and having a piston including a piston crown and a piston recess, includes the steps of injecting the fuel by the injector nozzle into the combustion chamber in the form of separated jets of the fuel having different inclinations relative to a top surface of the piston crown and selectively setting the inclinations of the fuel jets depending on an engine load.

For a spark ignited internal combustion engine having at least two inlet valves per cylinder each with a separate inlet passage and with a fuel injection device which injects fuel directly into the cylinder. An air charger for generating an air charge into one of the inlet passages and a connecting duct extending between the two inlet passages with a selectively opened and closed regulating device therein to apportion the flow of charge air through the separate inlet passages.

An exhaust-gas turbocharger for an internal combustion engine has an exhaust-gas turbine in the exhaust tract and a compressor in the intake tract, the exhaust-gas turbine and the compressor being connected via a shaft which is supported in a casing of the exhaust-gas turbocharger via at least one bearing. In order to improve the efficiency of the turbocharger, the bearing has a non-contact design, in that, when the exhaust-gas turbocharger is in operation, the shaft is held at a distance from, and so as to be virtually free of friction with, a bearing receptacle fixed to the casing.

Exhaust-gas turbocharger for an internal combustion engine

An exhaust gas turbocharger with an exhaust gas turbine and a radial compressor includes an impeller which pumps air through guide vanes or wedge guide elements into a helical passage. It is proposed that the guide vanes or wedge vane elements be guided for axial displacement in the casing of the radial compressor and be able to be shifted across the pumped stream of the impeller.
