The invention relates to a catalytic converter for treating exhaust gases of an internal combustion engine, having a housing through which an exhaust gas may flow and which has an inflow side and an outflow side, wherein, in the housing, there is formed a plurality of flow channels (4, 13) which is flowed through along a main throughflow direction from the inflow side to the outflow side, wherein, in the housing, there is arranged at least one pipeline (5, 12) which is flowed through by a fluid which is independent of the exhaust gas that is caused to flow through the flow channels (4, 13).

An exhaust gas heat recovery system for an internal combustion engine has a pump for conveying an operating fluid, an evaporator for converting the operating fluid from the liquid state to the gaseous state, and a condenser for liquefaction of the operating fluid, and having an expansion engine through which the gaseous operating fluid can flow. A sensor is arranged on the expansion engine with which a function of the expansion engine can be monitored. An exhaust system may have such an exhaust gas heat recovery system, and a method for the diagnosis of such an exhaust heat recovery system.

An exhaust gas purification structure of an outboard motor includes an exhaust gas pipe that has an exhaust gas passage through which exhaust gas of an engine can flow; and a catalyst that is provided in the exhaust gas passage and purifies the exhaust gas by allowing the exhaust gas to pass through the inside thereof. The exhaust gas pipe includes a coolant flow passage allowing a coolant that cools the exhaust gas to flow therethrough. An exhaust gas bypass passage allowing the exhaust gas to flow without passing through the catalyst is formed between the catalyst and an inner surface of the exhaust gas pipe forming the exhaust gas passage.

Combustion engines, and more particularly, integrating a supercritical fluid passageway into a cylinder head and/or cylinder block of an engine, and preferably, a combustion engine. Both a combustion engine system and a method of cooling a cylinder head in an internal combustion engine, utilizing supercritical fluid, are disclosed.

An injector includes a nozzle portion to inject fluid, a coil to generate a driving force to open and close the nozzle portion, and a molded resin that seals the coil. A cooling jacket has a flow path to cause cooling fluid to flow therethrough. The cooling jacket houses the injector and has an opening in an end opposite to the nozzle portion. A sealing material is filled in a space between the cooling jacket and the molded resin.

A vehicle comprises an internal combustion engine including an engine body and a catalyst device and a carbon dioxide recovery device recovering carbon dioxide contained in the exhaust is provided. The engine body, catalyst device, and carbon dioxide recovery device are mounted in the vehicle so that relationships X1>X2 and X2>X3 stand where a distance from a mounting position of the engine body to a mounting position of the carbon dioxide recovery device is X1, a distance from a mounting position of the catalyst device to the mounting position of the carbon dioxide recovery device is X2, and a distance from a mounting position of the engine body to a mounting position of the catalyst device is X3.

An exhaust component for an engine exhaust system includes a conduit for carrying exhaust gases, an outer wall, a fluid inlet, a fluid outlet, and a pattern of internal support structures. The conduit, outer wall, and internal support structures are formed from an additive material using an additive manufacturing process. A water cavity is defined between the conduit and the outer wall. The fluid inlet and outlet are in fluid communication with the water cavity. The pattern of internal support structures are integral with the conduit and with the outer wall, are disposed in the water cavity, and are arranged such that fluid flows from the fluid inlet through, between, or around the internal support structures to the fluid outlet. The fluid and its flow through the water cavity is adapted to absorb heat from hot exhaust gases flowing through the conduit during operation of the engine exhaust system.

An exhaust gas recirculation (EGR) cooler assembly can be used to perform heat exchange between cooling water and exhaust gas. The EGR cooler assembly includes an EGR cooler in which cooling water flows, and a diesel particulate filter (DPF) including a housing accommodating therein the EGR cooler and a filter unit for post-treatment of the exhaust gas. An inside of the housing is sectioned by a partition into a first space in which the EGR cooler is inserted and a second space in contact with the filter unit, and the partition has a flow hole formed thereon in order to allow the exhaust gas to flow to the EGR cooler.

A carbon dioxide capture system includes a first capture tank containing carbon dioxide absorbent material which operates to absorb carbon dioxide from a flow of exhaust gas from an internal combustion engine. A heat exchange loop is in heat exchange communication with the first capture tank and further in heat exchange communication with one of the flow of exhaust gas or a flow of engine coolant from the internal combustion engine. A heat exchange fluid is operable to flow through the heat exchange loop. The heat exchange fluid operates to transfer heat from the exhaust gas or the engine coolant to the first capture tank. The heat from the exhaust gas or the engine coolant operates to release a portion of the carbon dioxide absorbed by the carbon dioxide absorbent material in the first capture tank.

A vehicle includes an internal combustion engine. The internal combustion engine includes an exhaust passage, and a filter for collecting particulate matter contained in the exhaust gas. The vehicle includes a cooling fan for circulating air around a radiator and the filter. A control device of the vehicle executes an accumulated amount calculation process for calculating a particulate matter accumulated amount. The control device executes a regeneration process under a condition that the particulate matter accumulated amount exceeds a specified amount. The regeneration process is a process for regenerating the filter when the particulate matter collected on the filter is combusted. The control device executes a fan drive process for driving the cooling fan. When the regeneration process is being executed, the control device executes the fan drive process regardless of a coolant temperature under a condition that a vehicle speed is smaller than a specified speed.
