摘要:
A warm-up control device for an internal-combustion engine comprises a heat storage device for storing a heating medium heated during operation of the engine, supplies the heating medium stored in the heat storage device to a drive device (a transmission and the like) prior to the start of the engine or:at the start of the engine, and supplies the heating medium stored in the heat storage device to the drive device while maintaining a condition where the heating medium is circulated in the path excluding the heat storage device and including the drive device after the start of the engine. The warm-up control device supplies the heating medium heat-insulated and stored in the heat storage device during operation of the engine, and sets the ratio between the amount of the heating medium supplied from the heat storage device to the and the amount of the heating medium supplied from the heat storage device to the drive device, on the basis of the temperature of the engine and the temperature of the drive device. At the start of the internal-combustion engine, the heating medium can be supplied to the engine or the drive device efficiently, and the warm-up can be performed as required.

A fuel supply apparatus that supplies fuel to an internal combustion engine by injecting liquid fuel from a fuel injection valve into a suction port is configured by a microbubble generator that generates microbubbles and an ultrasonic wave generator that generates an ultrasonic wave depending on a gas in the microbubbles generated by the microbubble generator. In the fuel supply apparatus, the generated microbubbles are mixed into the liquid fuel that is supplied to the fuel injection valve, and the liquid fuel in which the microbubbles are mixed is irradiated with the ultrasonic wave depending on the driving state of the internal combustion engine. When the liquid fuel in which the microbubbles are mixed is irradiated with the ultrasonic wave, a temperature of the liquid fuel is raised instantaneously due to contraction of the microbubbles.

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.

It is an object of the present invention to improve the mixability of liquid hydrocarbon fuel and hydrogen gas and reduce the number of parts required for fuel supply means that supplies the two types of fuel. Disclosed is a hydrogen-fueled internal combustion engine that uses liquid hydrocarbon fuel and hydrogen gas as fuel. The hydrogen-fueled internal combustion engine comprises a fuel injection device for injecting hydrocarbon fuel; fuel supply means for supplying hydrocarbon fuel to the fuel injection device; and a microbubble generation device for generating microbubbles of hydrogen gas and mixing the generated microbubbles of hydrogen gas into liquid hydrocarbon fuel in the fuel supply means. The hydrogen gas microbubbles are supplied, for instance, to a fuel supply path (second fuel supply path) and fuel tank, which constitute the fuel supply means.

It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine includes an impulse valve common to all the cylinders arranged in the engine. The impulse valve is arranged in a communicating tube provided at the downstream side of a serge tank. An ECU executes impulse valve drive control. In the control, the ECU judges whether a rotation angle sensor which detects the open degree of the impulse valve has failed. If it is judged that the rotation angle sensor has failed, the ECU controls a drive motor and a drive circuit for driving a valve body so that a valve body of the impulse valve rotates inside the communicating tube. Here, the rotor of the drive motor which defines the rotation speed of the valve body has an rpm which is set in accordance with the mechanical rpm NE of the engine.

An internal combustion engine can use ammonia and a non-ammonia fuel which is easier to burn than ammonia as fuel. The non-ammonia fuel is directly injected into a combustion chamber by a non-ammonia fuel injector, and the injected non-ammonia fuel is ignited, whereby combustion of the air-fuel mixture in the combustion chamber is commenced. In the control system of the internal combustion engine, the injection timing of the non-ammonia fuel is advanced at a time when a ratio of ammonia in all fuel fed to the internal combustion engine is high in comparison with the time when the ratio is low. Therefore, a control system of an internal combustion engine capable of using ammonia and a non-ammonia fuel (gasoline, light oil, hydrogen, etc.) which is easier to burn than ammonia, which suitably feeds fuel and controls combustion in order to suitably burn an air-fuel mixture in a combustion chamber is provided.

A color conversion sheet realizing suppression of deterioration in a color conversion layer and improvement in light extraction efficiency is provided. The color conversion sheet includes: a color conversion layer converting a part of first color light as incident light to second color light having a wavelength longer than that of the first color light; and a pair of sealing sheets sandwiching the color conversion layer from a light incidence side and a light emitting side and each having an inorganic stack film on a substrate. Reflectance of the sealing sheet on the light incidence side to the second color light is higher than that to the first color light, and reflectance of the sealing sheet on the light emitting side to the first color light is higher than that to the second color light.
