Abstract: A controller is used for an internal combustion engine including a cylinder and a direct injection valve that injects gaseous fuel into the cylinder. A CPU of the controller executes acquisition of an in-cylinder pressure that is a pressure in the cylinder during one combustion cycle and a supply fuel pressure that is a pressure of the gaseous fuel supplied to the direct injection valve, and calculation of a backflow rate that is an amount of combustion gas flowing into the direct injection valve from the cylinder during one combustion cycle of the cylinder. In the calculation of the backflow rate, the CPU calculates the backflow rate such that the backflow rate becomes larger as the in-cylinder pressure increases and the backflow rate becomes larger as the supply fuel pressure decreases.

Abstract: A vehicle able to recover CO2 includes a CO2 recovery container holding an adsorbent adsorbing CO2 in gas. The vehicle is configured so that the adsorbent is taken out from the vehicle.

Abstract: A vehicle includes a processor that includes hardware. When an own vehicle is connected to an external network via a communication mesh network created by vehicle-to-vehicle communication that takes place between multiple vehicles, the processor outputs connection information indicating that the own vehicle is connected to the external network as information that is able to be visually recognized from outside of the vehicle.

Abstract: An information collection device according to the present disclosure is an information collection device that causes a small unmanned aerial vehicle to fly from a departure point to a destination and collects information at the destination using the small unmanned aerial vehicle, and includes a control device that causes the small unmanned aerial vehicle to fly from the departure point to the destination by transmitting a control signal to the small unmanned aerial vehicle by wireless information communication via a vehicle when determination is made that the wireless information communication is able to be executed with the small unmanned aerial vehicle via the vehicle located between the departure point and the destination.

Abstract: A CO2 recovery system used in a vehicle includes a CO2 recovery device recovering CO2 contained in inflowing gas; and a flow rate control device controlling flow rates of gases present in a plurality of different regions of the vehicle flowing into the CO2 recovery device. The gases present at the plurality of different regions include at least any two among air at an outside of the vehicle, air at an inside of the vehicle, and exhaust gas discharged from a body of an internal combustion engine of the vehicle.

Abstract: A control system for a vehicle having a CO2 capturing device configured to capture CO2 certainly from gas streams. The CO2 captured by the CO2 capturing device is desorbed from the CO2 capturing device by an energy available in the vehicle. A controller is configured to discharge the CO2 captured by the CO2 capturing device into the recovery station by energy delivered from the recovery station to the CO2 capturing device when the energy available in the vehicle is less than a predetermined value.
