In one or more embodiments, the present invention provides a vehicle heating system for a vehicle with an engine and a charge air cooler, the vehicle heating system including a high-temperature cooling circuit coupled to the engine, a low-temperature cooling circuit coupled to the charge air cooler and including a low temperature cooler, and a heating heat exchanger coupled to the low-temperature cooling circuit.

Vehicle heating system and method of using the same

An internal combustion engine comprising a dual flow turbocharger includes an annular support with at least one tongue-like end wherein the annular support is adjustable in a translational fashion along the turbines axis of rotation. Moving the annular support influences the degree of separation behavior of turbine channels by varying a tongue spacing to the rotor.

A method and system is provided for a turbocharged multi-cylinder internal combustion engine comprising a two-channel turbine and at least two groups of cylinders, wherein one group of cylinders is switchable responsive to an engine load over a threshold. Exhaust lines of each group of cylinders are arranged in a targeted manner to couple with the turbine such that the switchable group is attached to one channel and the active group is attached to the other channel to reduce the difference in distances that pressure pulses travel, wherein a shut-off element is provided in the channel attached to the switchable group and may be moved to block exhaust flow through the channel when the cylinders are deactivated, thus improving the partial deactivation and turbocharging characteristics of the engine.

A supercharged internal combustion engine having at least two exhaust-gas turbochargers is provided. The engine includes a first exhaust manifold and a second exhaust manifold which are permanently connected to one another upstream of the two turbines of the turbochargers via at least one connecting duct which cannot be closed off. In this way, overflow of exhaust from the one exhaust manifold may be transferred to the other exhaust manifold.

A supercharged internal combustion engine comprising a two channel turbine fluidly connects the two channels within the turbine housing by virtue of at least one opening in the housing wall which separates the two channels wherein at least one displaceable wall part is provided which serves for opening up the opening in the housing wall to optimize the performance of the turbine responsive to the exhaust gas flow rate.

Supercharged internal combustion engine with two-channel turbine and method

A supercharged internal combustion engine wherein a two-channel turbine comprising a shut-off body positioned within a flow transfer duct within a turbine housing fluidly couples the two channels of a turbine housing to one another via the transfer duct responsive to the exhaust gas flow rate to enable better operation of the turbocharger.

Embodiments for a supercharged engine are presented. In one example, a supercharged engine includes a cylinder head having at least two cylinders, each cylinder having at least one outlet opening for discharging exhaust gases and each outlet opening being adjoined by an exhaust line, with exhaust lines of at least two cylinders merging to form an overall exhaust line within the cylinder head so as to form an integrated exhaust manifold, at least two turbines arranged in series, the two turbines being of different size and arranged downstream of the exhaust manifold in the overall exhaust line, a distributor housing in which the overall exhaust line downstream of the manifold enters into and leads through to a small turbine of the two turbines, and a first turbine housing which accommodates the small turbine including at least one coolant jacket in order to form a liquid cooling arrangement.

Systems and methods for operating a twin flow supercharged engine are provided. The exhaust lines of engine cylinders are grouped into separate manifolds connected to respective inlet ducts of the twin-flow turbine. The inlet ducts of the twin-flow turbine are of different sizes, with different-sized cross sections and/or different-sized exhaust-gas volumes. The exhaust line of a manifold with a smaller exhaust-gas volume is connected to the larger inlet duct, and the exhaust line of a manifold with the larger exhaust-gas volume is connected to the smaller inlet duct.

For an internal combustion engine having two cylinder banks forming a V-shaped cylinder block, a turbocharger system including a high pressure turbocharger disposed in a valley between the cylinder banks, a first low-pressure turbocharger disposed adjacent an outer side of one of the cylinder banks, and a second low-pressure turbocharger disposed adjacent an outer side of the second cylinder bank. Intake and exhaust ducts connect the components of the engine and turbocharger system to and electronically controlled valves associated with the ducts permit the system to operate either in a split series mode or a low-pressure-only mode.

Split-series sequential turbocharged engine

The invention relates to a radial compressor having a suction-side opening and a pressure side. A swirl generator is placed upstream of the radial compressor. The swirl generator, has an inlet portion which is angularly configured relative to the outlet opening, the outlet opening facing the suction-side opening of the swirl generator. The swirl generator further has adjustable baffle plates arranged concentrically around the outlet opening.

The invention relates to a supercharged internal combustion engine having at least two cylinder groups of at least one cylinder each, both cylinder groups being equipped with an exhaust pipe, and the two exhaust pipes being in communication with one another, and having two exhaust gas turbochargers, the turbines of which are connected in parallel, with their compressors connected in series, and having an exhaust gas recirculation line which upstream of one of the two turbines branches off from the exhaust pipe assigned to this turbine and opens out into the common intake line. An advantage of this invention is that it provides a supercharged internal combustion engine which overcomes the drawbacks which are known from the prior art and can be used to realize high exhaust gas recirculation rates and high boost pressures, in particular simultaneously, in all the load ranges of the internal combustion engine.
