Abstract: A gas recovery system, which recovers a recovery target gas from a mixed gas by an electrochemical reaction, includes a recovery unit into which the mixed gas is introduced and an electrochemical cell disposed in the recovery unit. The electrochemical cell includes a working electrode and a counter electrode. When a voltage is applied between the working electrode and the counter electrode, electrons are supplied from the counter electrode to the working electrode, and adsorbent of the working electrode bonds with the recovery target gas. The electrochemical cell is arranged so as to come in contact with the recovery target gas. The electrochemical cell has a wall surface forming part on a contact surface that comes in contact with the recovery target gas, and the wall surface forming part has a wall surface that faces in a flow direction of the recovery target gas.

Abstract: A carbon dioxide recovery system, which is configured to separate and recover carbon dioxide from a carbon dioxide containing gas, includes an adsorption unit that includes an adsorbent material that is configured to adsorb and desorb the carbon dioxide. The adsorbent material is configured to radiate heat in response to adsorption of the carbon dioxide and is configured to absorb the heat in response to desorption of the carbon dioxide. The adsorption unit is one of a plurality of adsorption units, and adjacent two adsorption units among the plurality of adsorption units contact with each other. When one of the adjacent two adsorption units adsorbs the carbon dioxide, another one of the adjacent two adsorption units desorbs the carbon dioxide.

Abstract: A carbon dioxide recovery system includes: an adsorber configured to adsorb and desorb carbon dioxide; a supply channel through which supply gas passes; a storage section configured to store carbon dioxide desorbed from the adsorber; and a gas supply section supplying carbon dioxide stored in the storage section to the adsorber. The carbon dioxide recovery system is operated in an adsorption mode, a desorption mode or in a desorption preparation mode. In the adsorption mode, the adsorber adsorbs CO2 contained in the supply gas supplied through the supply channel. In the desorption mode, the adsorber desorbs the adsorbed CO2, and the storage section stores CO2 desorbed from the adsorber. In the desorption preparation mode, the gas supply section supplies CO2 stored in the storage section to the adsorber during a time from an end of the adsorption mode to a start of the desorption mode.

Abstract: A carbon dioxide recovery device includes: an adsorption unit that includes a plurality of electrochemical cells, each of which includes a working electrode and a counter electrode; a receiver that receives the adsorption unit; a plurality of gas inlets, each of which is provided to the receiver and is configured to introduce a subject gas containing carbon dioxide; and a plurality of doors, each of which is configured to open and close a corresponding one of the gas inlets. The gas inlets are respectively configured to introduce the subject gas into an inside of the receiver in a corresponding direction perpendicular to a cell stacking direction of the electrochemical cells and are configured to introduce the subject gas into the receiver from all around the receiver along a circumferential direction of the receiver that is perpendicular to the cell stacking direction.

Abstract: An internal combustion engine control apparatus includes a fuel injection apparatus injecting fuel into a combustion chamber a plurality of times during a single cycle, and controls an internal combustion engine that performs compression combustion. The internal combustion engine control apparatus includes an injection command unit and an injection specification determining unit. The injection command unit commands the fuel injection apparatus to perform: a main injection for a main combustion that generates torque; and a preceding injection that is performed at a stage before the main injection. The injection specification determining unit determines a penetration force of a spray produced by the preceding injection or an injection direction of the preceding injection, such that a range of reach of the spray produced by the preceding injection is closer to a nozzle hole of the fuel injection apparatus than a range of reach of a spray produced by the main injection.
