A phosphor sheet-forming resin composition uses a low-cost resin material having high light fastness and low visible light absorption and is capable of providing a phosphor sheet at low cost with deterioration of a phosphor due to moisture being suppressed. The phosphor sheet-forming resin composition contains a film-forming resin composition and a powdery phosphor that emits fluorescence when irradiated with excitation light. The film-forming resin composition contains a hydrogenated styrene-based copolymer, and uses a sulfide-based phosphor as the phosphor. Examples of the hydrogenated styrene-based copolymer include hydrogenated products of styrene-ethylene-butylene-styrene block copolymers. CaS:Eu is used as a preferred sulfide-based phosphor.

An ammonia burning internal combustion engine can feed ammonia and a highly combustible substance burning easier than ammonia to a combustion chamber. When the amount of ammonia fed into the combustion chamber is increased or when the ratio of the amount of the ammonia to the total amount of the ammonia and the highly combustible substance fed into the combustion chamber is increased, the operating parameters of the internal combustion engine are controlled so the air-fuel mixture fed into the combustion chamber is made easier to burn. As a result, an ammonia burning internal combustion engine designed to suppress a drop in combustibility of auxiliary fuel due to ammonia, can be provided.

A fuel production system and has an object to provide a fuel production system that is capable of producing HC with high efficiency by using variable energy. A first device is a CO/H2 generating device that simultaneously generates CO and H2 by performing electrolysis on CO2 and water. A second device is a H2 generating device that generates H2 by performing electrolysis on water. When electric power derived from natural energy is used, the first device is seriously affected by its variation. Therefore, a steady-state portion of generated electric power (straight line in a figure) is supplied to the first device while the remaining variable portion (the portion above the straight line) is supplied to the second device.

A phosphor sheet-forming resin composition uses a low-cost resin material having high light fastness and low visible light absorption and is capable of providing a phosphor sheet at low cost with deterioration of a phosphor due to moisture being suppressed. The resin composition contains a film-forming resin composition and a powdery phosphor that emits fluorescence when irradiated with excitation light. The film-forming resin composition used contains a polyolefin copolymer component and a maleic anhydride component. A sulfurized phosphor, an oxide-based phosphor, or a phosphor mixture thereof is preferably used as the phosphor.

A vehicle is provided with an engine, an H2 and CO tank, a CO2 reclaimer, an electrolytic solution tank, an electrolyser, a water tank and the like. During operation of the engine, an exhaust gas is introduced into an absorbing liquid in the CO2 reclaimer so as to recover CO2 in the exhaust gas and to store the same in the electrolytic solution tank. While supplying the absorbing liquid having absorbed CO2 and water to the electrolyser from the electrolytic solution tank and the water tank, respectively, electric power is supplied to the electrolyser. As a result, a mixed gas composed of CO and H2 from CO2 and water. The generated mixed gas is temporarily stored in the H2 and CO tank and is supplied to the engine.

To improve an ignitability to a fuel having a low compressed ignitability in a combustion chamber in a compressed self-ignition diffusive combustion mode operation. In a multi-fuel internal combustion engine operated by introducing at least one type of fuel among at least two types of fuels having different properties into a combustion chamber or introducing a mixed fuel composed of at least the two types of fuels into the combustion chamber, an electronic control unit is provided with a fuel characteristics detection means that detects an ignitability index value as an index showing a compressed ignitability of a fuel itself introduced into the combustion chamber, and a fuel injection control means that previously injects, when a compressed self-ignition diffusive combustion is performed using a fuel in the combustion chamber, which is determined to have a low compressed ignitability based on the ignitability index value, the fuel at a predetermined timing in a period from an intake stroke to a compression stroke, and thereafter mainly injects the fuel and introduces the fuel having the low compressed ignitability into the combustion chamber.

An ammonia burning internal combustion engine capable of using ammonia as fuel comprises an exhaust purifying catalyst purifying ammonia and NOx in an inflowing exhaust gas and an inflowing gas control system controlling a ratio of ammonia and NOx in the exhaust gas flowing into the exhaust purifying catalyst. The inflowing gas control system controls control parameters of the internal combustion engine so that the ratio of the ammonia and NOx in the exhaust gas flowing into the exhaust purifying catalyst becomes a target ratio. As a result, an internal combustion engine capable of purifying unburned ammonia and NOx in an exhaust gas well by a post-treatment system is provided.
摘要:
A medium circulating apparatus of engine oil, which improves startability and warm up ability of an internal combustion engine, includes a microbubble generator that generates microbubbles and mixes the microbubbles into the circulating engine oil. Further, the medium circulating apparatus includes a medium temperature acquiring unit that acquires a temperature of the engine oil. The microbubbles are generated by the microbubble generator when the temperature of the engine oil is less than or equal to a predetermined value in order to decrease a viscosity, a heat conductivity, and a heat capacity of the engine oil in which the microbubbles are mixed.
