A motor vehicle heat exchanger system includes a closed circuit for a working medium and an evaporator for evaporation of the working medium. The evaporator includes at least two evaporator cassettes having an exhaust gas channel formed between the evaporator cassettes. Each evaporator cassette includes a capillary structure and a liquid side and a vapor side. A medium feed is provided on the liquid side for liquid working medium.

A marine muffler capable of handling both marine engine exhaust gas and marine engine cooling water includes a double wall baffle partitioning the muffler interior so as to function as a cooling water conduit. The cooling water conduit includes an inlet disposed external to the main muffler housing and an outlet configured and disposed so as to discharge the engine cooling water into the exhaust duct connected to the muffler outlet. The muffler is thus able to convey the engine cooling water through the muffler housing within a dedicated conduit while maintaining the cooling water separate from the exhaust gas. A muffler that is adapted to handle both the exhaust and cooling water flowing from a marine engine allows for the elimination of engine cooling water piping.

System (1) for the purification of exhaust gases (S) of an endothermic engine (100), comprising at least one duct (2) for exhausting the gases produced by said endothermic engine, means (3) for cooling said exhaust gases which cross said duct (2) so that to cause, at least in part, the condensation of the water vapor contained in said exhaust gases in water (AC), and means (4) for separating the condensed water (AC), which is condensed by said cooling means along the exhaust duct, from the exhaust gases and for deviating it along a secondary duct (10), said system being characterized by further comprising filtering means (5), which are arranged downstream of said separating means (4) along said secondary duct (10), for filtering said condensed and separated water (AC).

A V-type engine, an outboard motor, and a ship capable of restricting exposure of a catalyst to water. Cylinders where pistons operate are arranged in a V-shape, a crankshaft driven by driving of the pistons is disposed vertically, and exhaust pipes communicating with exhaust openings in the respective banks of a cylinder head and a catalyst holder that holds a catalyst in a merge portion where the exhaust pipes are merged in a site located on an upper side of the banks are included.

An exhaust heat recovery apparatus is installed proximate an engine and at a front side of a warm-up catalytic converter in an exhaust system, where the exhaust system includes an exhaust line connected with the engine, and the warm-up catalytic converter is installed at the exhaust line. The exhaust heat recovery apparatus includes a bellows unit which is of a dual-pipe type and exchanges heat between exhaust gas emitted through the exhaust line and coolant circulating from a cooling system to the engine.

A method for operating an engine system in an internal combustion engine comprising during a first operating condition, circulating coolant through a coolant jacket in a turbine housing at least partially enclosing a turbine rotor and during a second operating condition, replacing coolant in the coolant jacket with air from a venting reservoir.

A thermal overload of an internal combustion engine and of cooling system of a combustion machine due to a raising of the temperature of the exhaust gas flowing through an exhaust gas line of the combustion machine, which is provided as a measure to desulfurize a NO.sub.x storage catalytic converter and/or to regenerate a particulate filter, is prevented in that before and/or during this measure, the cooling output for the coolant flowing through the cooling system is systematically increased in order to achieve a lowering of the coolant temperature to a value range that lies below what would normallythat is to say, without the simultaneous desulfurization of the NO.sub.x storage catalytic converter and/or without the regeneration of the particulate filterhave been provided for the operation of the combustion machine in a corresponding operating state of the internal combustion engine.

Heat recovery component for an exhaust gas system of an internal combustion engine, comprising an inlet, an outlet, a heat recovery branch conduit comprising a heat recovery branch conduit inlet, a heat recovery branch conduit outlet, and a heat exchanger arranged in the heat recovery branch conduit, a bypass branch conduit being separate from the heat recovery branch conduit, and a valve being configured to be rotatable between a heat recovery end position and a bypass end position, the valve being arranged to be rotatable around a rotation axis located in the bypass branch conduit, wherein the valve comprises a bypass valve flap and a heat recovery valve flap, the bypass valve flap and the heat recovery valve flap being operatively connected by a support.

A waste heat recovery system in thermal communication with an exhaust conduit of an internal combustion engine of a vehicle includes a condenser. The condenser includes a working fluid conduit configured to connect to a working fluid loop of the waste heat recovery system and a coolant fluid conduit configured to connect to a coolant fluid loop used to cool the internal combustion engine of the vehicle. The coolant fluid conduit includes a coolant fluid inlet and a coolant fluid outlet. The waste heat recovery system also includes a coolant fluid bypass fluidly connected between the coolant fluid inlet and the coolant fluid outlet. The coolant fluid bypass includes a coolant fluid control valve configured to vary a portion of the volume of coolant fluid that flows through the coolant fluid bypass based on a temperature of a working fluid in the working fluid loop.

A power system for converting waste heat from exhaust gases of an internal combustion engine to electrical energy includes an aftertreatment assembly positioned within a first housing. The power system also includes an evaporator assembly positioned within a second housing. The evaporator assembly is positioned directly adjacent the aftertreatment assembly. The evaporator assembly includes a first portion of a working fluid loop in thermal communication with a first length of an exhaust conduit that extends from the aftertreatment assembly into the second housing. The power system also includes a power pack positioned inside a third housing. The power pack is positioned directly adjacent the evaporator assembly opposite to the aftertreatment assembly. The power pack includes a tank, a condenser, a pump and an expander fluidly connected by a second portion of the working fluid loop. The second portion is fluidly connected to the first portion of the working fluid loop.
