  • Patent number: 11964232
    Abstract: Provided is a carbon dioxide recovery system that separates CO2 from a CO2-containing gas containing CO2 by an electrochemical reaction, and comprises an electrochemical cell comprising a working electrode containing a CO2 adsorbent, and a counter electrode. Application of a voltage between the working electrode and the counter electrode causes electrons to be supplied from the counter electrode to the working electrode, and enables the CO2 adsorbent to bind to CO2 as electrons are supplied. The CO2 adsorbent is a crystalline porous body, and has a molecular structure in which a functional group that exchanges electrons and binds to CO2 is regularly arranged.

  • Publication number: 20220123338
    Abstract: An energy management system is provided with a fuel synthesizing apparatus, a power generation apparatus, a CO2 recovering unit, a compressor, a CO2 storage unit, a CO2 pressure reducing unit and a heat recovery unit. The fuel synthesizing apparatus generates hydrocarbon from H2O and CO2 using externally supplied power. The power generation apparatus generates power using the hydrocarbon. The CO2 recovering unit recovers CO2 from an exhaust gas exhausted from the power generation apparatus during a power generation. The compressor compresses the recovered CO2. The CO2 storage unit stores the CO2 compressed by the compressor. The CO2 pressure reducing unit depressurizes the CO2 stored in the CO2 storage unit in order to supply the fuel synthesizing apparatus therewith. The heat recovery unit recovers heat from the CO2, the heat having been stored in the CO2 when compressed or depressurized.

  • Patent number: 10538234
    Abstract: A vehicle control device that includes a search unit that searches, based on geographic information to be supplied from a navigation device, for a deceleration start position before a downhill that is suited to regeneration by a motor; and a charge level control unit that performs, when a vehicle reaches the deceleration start position, deceleration control for reducing a charge level of a battery by reducing a vehicle speed. When the charge level control unit performs the deceleration control, the vehicle speed is reduced by reducing a driving force of the vehicle to a level at which only motor output is used as the driving force.

  • Patent number: 10232852
    Abstract: A travel control apparatus is provided with: a speed controller that controls speed of a vehicle having an internal combustion engine; and a determination part that determines an emission deterioration state of the internal combustion engine. The speed controller is configured to execute burn-and-coast control that repeatedly executes burn control in which the vehicle is accelerated by driving force of the internal combustion engine, and coasting control in which the vehicle is driven by inertia, by stopping the generation of the driving force or rotation of the internal combustion engine. The speed controller is configured to execute emission suppression control that suppresses emissions by adjusting the burn-and-coast control when the emission deterioration state of the internal combustion engine is determined by the determination part.

  • Publication number: 20180179995
    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.

  • Patent number: 9469291
    Abstract: A vehicle includes an engine, a first MG, a second MG, a main battery which can be charged and discharged, and a heating device. The heating device includes an exhaust heater which uses an exhaust heat of the engine, and a heat pump system which uses an electric power of the main battery. A hybrid control device determines a start timing of the heating device, based on a coolant temperature and a SOC. Specifically, the start timing of the heating device is determined such that a timing that the coolant temperature reaches a target temperature matches a timing that the SOC reaches a target value. After a warming-up operation is completed, an EV travelling of the vehicle can be executed according to the electric power of the main battery charged in the warming-up operation, and a fuel consumption of the engine is improved.
