Device for heat transfer between a first fluid and one second fluid includes a housing with first housing element, second housing element and heat transfer element. Housing is developed with a first connecting fitting and a second connecting fitting for each fluid. Heat transfer element is disposed in a volume completely enclosed in a housing and is developed for through-conduction of the first fluid. Housing is developed for conduction of the second fluid about the heat transfer element. Connecting fittings for second fluid are either disposed on the first housing element and the connecting fittings for the first fluid are disposed on the second housing element, wherein within the second housing at least one flow path for conducting the first fluid is implemented which extends between a connecting fitting and a collector region or the connecting fittings for the fluids are disposed on the first housing element.

The invention relates to an internal combustion engine that comprises a first Brayton cycle comprising a mixed ionic-electronic conducting (MIEC) membrane that separates the O.sub.2 from the air such that the suctioned air current is free from N.sub.2; a second Brayton cycle combined in a binary manner with the first Brayton cycle and nested with a cycle selected from an Otto cycle and a diesel cycle performed by means of oxy-combustion. The second Brayton cycle transmits mechanical energy and thermal energy from exhaust gases to the first Brayton cycle. The first Brayton cycle provides to the second Brayton cycle compressed O.sub.2 from the MIEC membrane. By means of the present engine, the NOx emission into the atmosphere is prevented by the separation of N.sub.2 in the MIEC membrane.

An intake device for an internal combustion engine includes: a main pipe having an upstream end forming a suction port and a downstream end configured to be connected to an intake port of an internal combustion engine main body; a compressor of a supercharger provided in the main pipe; an intercooler provided in the main pipe at a position downstream of the compressor and including a cooling part, an upstream header provided upstream of the cooling part, and a downstream header provided downstream of the cooling part; a throttle valve disposed in the main pipe at a position downstream of the intercooler; a bypass pipe having a first end and a second end, the bypass pipe being connected to a part of the main pipe between the cooling part and the throttle valve; and a catch tank provided in the bypass pipe and configure to catch condensed water.

A method includes operating a spark ignition engine and flowing low pressure exhaust gas recirculation (EGR) from an exhaust to an inlet of the spark ignition engine. The method includes interpreting a parameter affecting an operation of the spark ignition engine, and determining a knock index value in response to the parameter. The method further includes reducing a likelihood of engine knock in response to the knock index value exceeding a knock threshold value.

A waste heat recovery system for an engine system includes a first charge air cooler in communication with a working fluid path of the waste heat recovery system. The first charge air cooler includes a first waste heat recovery core and a first cooling fluid core. The first waste heat recovery core includes a first working fluid inlet configured to receive a working fluid from the working fluid path. The first working fluid conduit is coupled to the first working fluid inlet and a first working fluid outlet. The first cooling fluid core includes a first cooling fluid inlet in fluid communication with a cooling fluid source and a first cooling fluid conduit fluidly coupled to the first cooling fluid inlet and a first cooling fluid outlet. The first cooling fluid conduit is configured to direct cooling fluid from the first cooling fluid inlet to the first cooling fluid outlet.

An intake system of an engine mounted on a vehicle where a cabin is air-conditioned by an air conditioner, is provided. A heat exchanger of an evaporator of the air conditioner is divided into a first heat exchanger and a second heat exchanger that are mutually independent, and an air passage includes a first division passage and a second division passage. The intake system cools intake air utilizing a part of the air conditioner, and includes a connecting passage that guides first air cooled by passing through the first heat exchanger, a passage switch, and a controller. When the controller determines that a cooling demand for the intake air exists, it controls the first air to flow into an intake passage through the connecting passage, and when the controller determines that there is no cooling demand, it controls the first air to flow into the first division passage.

A control device for an engine is provided, which includes a combustion chamber formed by a cylinder and a piston, an intake air amount adjuster that adjusts an intake air amount supplied to the combustion chamber, a controller switchable of a combustion mode between a fuel-lean first combustion mode and a stoichiometric second combustion mode based on an engine operating state, and an intake air cooler that cools the intake air supplied to the combustion chamber. The controller controls the intake air cooler to start intake air cooling in response to a request for switching the combustion modes, and after the intake air cooling is started, controls the intake air amount adjuster to start the switching of the combustion modes, and then controls the intake air cooler and the intake air amount adjuster so that the switching of the combustion modes ends after the intake air cooling is finished.

A dual entry turbine of a compression device includes a housing having a first inlet and a second inlet, and a first outlet and a second outlet. A turbine impeller is arranged within the housing. The turbine impeller has a first gas path and a second gas path. A first flow path extends from the first inlet to the first outlet via the first gas path and a second flow path extends from the second inlet to the second outlet via the second gas path. The first flow path and the second flow path being fluidly separate from one another.

An engine system includes a charge-air cooler, a separator for separating water from an airflow, and an engine. The separator causes an airflow from the charge-air cooler to strike one or more partitions and change directions via a serpentine path such that water is separated out of the airflow before the airflow reaches the engine.
