The cooling device for a power source for a ship propulsion device that pumps up cooling water, from which foreign matters with sizes that cause clogging of a cooling water route have been removed, supplies the cooling water to a cooling water passage (30), and discharges the cooling water to outside after cooling a power source (10) includes: a filtration device (40, 40A, 40B) provided in the cooling water route to filtrate foreign matters remaining in the cooling water, and the filtration device is of a cartridge type that incorporates a filter (45, 72) for filtration disposed in a main water passage (P1) and a valve member (46, 66) configured to open and close a bypass water passage (P2) and that is configured such that in a case in which clogging occurs in the filter, the valve member opens to cause the cooling water to flow via the bypass water passage.

A tank system (1) for a motor vehicle having an internal combustion engine to which fuel is supplied from a tank (2), wherein the tank (2) is assigned, in a ventilation path to the atmosphere (7), a flushable filter device (6, 6) for being loaded with hydrocarbon vapors of the fuel. The filter device (6, 6) has multiple mutually separate activated carbon filters (6). All of the activated carbon filters (6) are connected permanently in parallel. In this way, the ventilation resistance from the tank in the direction of the atmosphere can be kept low.

An apparatus and process for separating and removing CO.sub.2 generated by one or more passengers in the air in the interior of a cabin of a vehicle. Provided are: —a first stream of the air from the interior of the cabin to an interior of a container holding a loose particulate sorbent for CO.sub.2; —a second stream of air depleted in CO.sub.2 from the interior of the container holding the sorbent to an interior of the cabin; —a third stream of the air from exterior of the cabin to the inferior of the container holding the sorbent; and —a fourth stream of air enriched in CO.sub.2 from the interior of the container holding the sorbent to an exterior of the cabin.

An air purification device includes an adsorption block, a housing, an introduction port for indoor air, an introduction port for heated air, a return port for indoor air, and a discharge port for used regeneration air. The adsorption block adsorbs purification target substances in indoor air, and is regenerated by dispersing the adsorbed purification target substances by circulating heated air. The housing accommodates the adsorption block therein. The introduction port for indoor air and the introduction port for heated air are provided on one end side of the housing. The return port for indoor air and the discharge port for used regeneration air are provided on the other end side of the housing. An insulating layer is provided between the housing and an outer surface of the adsorption block.

A method of air pollution filtration in a vehicle is disclosed. A plurality of purification devices are provided to detect and transmit an inside-device gas detection datum, respectively, for intelligently selecting and controlling the activation of filtering the air pollution in the inner space of the vehicle. An in-car gas exchange system and a connection device are provided. The connection device receives and compares the respective inside-device gas detection datum, and selectively transmits a control instruction to drive the in-car gas exchange system and the purification devices. The movement of the air pollution is accelerated by the gas convention of the in-car gas exchange system, so that the air pollution is directionally moved toward the corresponding one of the purification devices adjacent to the air pollution for filtration. The air pollution in the inner space of the vehicle is filtered rapidly, so as to provide clean, safe and breathable air.

The present disclosure provides a compressed air processing system of which the operation of supplying compressed air and the regeneration operation can be efficiently controlled by an electronic control unit. In particular, the present disclosure is characterized in that the pressure of a regeneration sequence valve installed in a regeneration line is increased over a set pressure by controlling a valve, which is electronically controlled, to switch, so the opening time of the regeneration line is delayed in comparison to the opening time of an unloader valve, whereby regeneration efficiency is improved.

A system for exhaust gas remediation includes an engine, a plasma reactor, and a pulse source. The engine emits exhaust gas that includes NO molecules and NOx molecules. The plasma reactor includes an internal chamber that is fluidly connected to the engine such that the exhaust gas flows into the internal chamber. An electrode is disposed within the internal chamber of the plasma reactor. The electrode is electrically coupled to an electrical pulse source. The electrical pulse source delivers electrical pulse to the electrode to form a plasma from the exhaust gas, which removes at least a portion of the NO molecules and at least a portion of the NOx molecules.

A device for scrubbing carbon molecules from the ambient atmosphere includes a housing, a carbon-capture filter, and a holding mechanism to hold the device in operable association with an automobile. A housing may be perforated and constructed to removably hold a filter. A filter can include a hydroxide chemical compound in granular form. A holding mechanism may anchor the device to a grille, under-hood element, or in operable association with a tailpipe of an automobile. Sometimes, the device includes a color-changing indicator to indicate end-of-life of a filter. A decorative emblem may be included to obscure the device from casual observation by a passerby.

An exhaust gas treatment system capable of purifying exhaust gas containing moisture includes superheated steam generating pipes (20, 40) and a housing (10). The superheated steam generating pipe (20, 40) is formed of a material capable of generating heat by energization, and has a flow path (200, 400) through which exhaust gas can flow, and moisture contained in the exhaust gas flowing through the flow path is converted into superheated steam by the heat. The housing (10) is provided to accommodate the superheated steam generating pipe, is formed to allow the exhaust gas before being introduced into the flow path to flow therethrough and can preheat the exhaust gas by the heat of the superheated steam generating pipe.

A method and installation for removing a gas from a flow of a gas mixture. A first liquid (82) is introduced in the flow (106) for evoporative cooling and saturation of the gas mixture. Small droplets of a second liquid (84) are provided which are capable of adsorbing and dissolving said gas and of a size small enough not to be sedimented by gravitation and big enough to be centrifugally separated. The small droplets are sprayed into the flow for adsorbing and dissolving said gas into the droplets, and the small droplets are centrifugally separated from the flow.
