Abstract: To provide a novel power train system capable of improving fuel efficiency, reducing harmful components of an exhaust gas, and improving an output by adjusting a composition of a gas component of the exhaust gas in accordance with an operation condition. Therefore, provided is a power train system including a gas component separation unit (2) which extracts a plurality of gas components having different specific heat ratios from an exhaust gas of a spark ignition type internal combustion engine (1), a recirculation unit which recirculates the plurality of gas components to a combustion chamber of the internal combustion engine, and a ratio adjustment unit (3) which adjusts a ratio of the plurality of gas components recirculated to the combustion chamber in response to an operation state of the internal combustion engine. A composition of a gas recirculated to the internal combustion engine can be adjusted depending on various operation conditions. Accordingly, it is possible to improve fuel efficiency, reduce harmful components of an exhaust gas, and improve an output in a wide range of operation conditions of the internal combustion engine.

Abstract: Provided is an electric power supply system which includes a plurality of electric power sources and supplies electric power corresponding to demanded electric power. In supplying electric power to the outside from a vehicle which constitutes one of the electric power sources, the electric power supply system realizes generation of power by an engine at high efficiency while maintaining a balance between power income and expenditure. In supplying electric power from the vehicle, an amount of electric power generated by an engine mounted on the vehicle is decided based on information supplied from an external device such as transition over time in an amount of electric power demand including future prediction and transition over time in an amount of electric power which is suppliable from other electric power sources including future prediction.

Abstract: An electronic control device for mixed hydrogen combustion includes a combustion timing detection unit that detects the combustion timing of an engine; and an abnormal state detection unit that detects an abnormal state, in which a type of abnormality occurring in the engine has been determined, on the basis of the combustion timing and a second fuel supply ratio calculated from the supply amount of hydrocarbon fuel supplied by a first fuel supply device and the supply amount of a second fuel supplied by a second fuel supply device. A control mode determination unit determines a control mode corresponding to the abnormal state, controls the supply amount of hydrogen to be supplied by the second fuel supply device on the basis of the control mode, and outputs the control mode to an engine controller for controlling the engine.

Abstract: Provided is a CO2 recovery device of an internal combustion engine capable of efficiently recovering CO2 emitted from an internal combustion engine or CO2 in the air, and of efficiently synthesizing methane using CO2. A CO2 recovery device of an internal combustion engine includes a CO2 capturing material disposed at a through channel of gas including CO2 to capture CO2 in the gas, and methanation catalyst to let CO2 desorbed from the CO2 capturing material react with H2 obtained from a H2 supply source to generate methane. The CO2 recovery device has a function to raise temperature of the CO2 capturing material using heat generated from the internal combustion engine to desorb CO2.
