Abstract: A cooling device for an internal combustion engine includes a pump portion, a circulation water passage, a thermostat configured to switch between a state where the coolant is circulated to a heat exchange water passage on which a radiator is disposed and a state where the coolant is not circulated to the heat exchange water passage, and a control unit configured to control the pump portion. The control unit is configured to control a three-way valve such that a first pump and a second pump are connected in parallel when the thermostat switches to the state where the coolant is circulated to the heat exchange water passage and controls the three-way valve such that the first pump and the second pump are connected in series when the thermostat switches to the state where the coolant is not circulated to the heat exchange water passage.

Abstract: A flow control valve includes a housing that includes a fluid inlet and a fluid outlet; a valve body that together with the housing, forms a first chamber with a variable volume and a second chamber with a variable volume; a communication passage that connects the first chamber and the second chamber together; and an urging portion that urges the valve body in a direction in which the volume of the first chamber decreases. When the valve body moves in a direction to increase the volume of the first chamber against urging force of the urging portion, the valve body moves closer to the fluid outlet and reduces a degree to which the second chamber is communicated with the fluid outlet.

Abstract: The present invention provides an internal combustion engine includes: a turbocharger arranged in exhaust passage; EGR passage branching off from the exhaust passage downstream of a turbine of the turbocharger and connected to intake passage; a burner device arranged in the exhaust passage between the turbine and the portion where the EGR passage branches off to increase exhaust temperature; a bypass passage branching off from the exhaust passage between the turbine and the burner device and connected to the EGR passage; and a bypass valve to adjust flow rate of exhaust gas passing through bypass passage. When flow rate of the exhaust gas is increased, the bypass valve is open, and part of the exhaust gas is guided to the bypass passage. The flow rate of the exhaust gas to be supplied to the burner device is reduced, and the ignition performance of the burner device is ensured.

Abstract: An internal combustion engine according to the present invention includes an exhaust treatment apparatus provided in an exhaust passage, and a burner apparatus provided upstream of the exhaust treatment apparatus to increase an exhaust temperature. The burner apparatus includes at least a fuel addition valve that allows fuel to be added into exhaust and ignition means for igniting the fuel added via the fuel addition valve. The fuel addition valve is driven open when fuel is added via the fuel addition valve. The amount of fuel added via the fuel addition valve per unit time is increased beyond a predetermined reference amount when the detected amount of intake air exceeds a predetermined threshold value. The probability of successful ignition by the ignition apparatus is increased, and a flame is prevented from being blown out. Thus, the burner apparatus can demonstrate sufficient ignition performance and sufficient combustion performance.

Abstract: An internal combustion engine according to the present invention includes an exhaust treatment apparatus provided in an exhaust passage, and a burner apparatus provided upstream of the exhaust treatment apparatus to raise exhaust temperature. A valve driving state of at least one of an intake valve and an exhaust valve is controlled so as to reduce a flow rate of exhaust gas passing through the burner apparatus when the flow rate of the exhaust gas is equal to or larger than a predetermined value. Possible flame blow-out in the burner apparatus can be prevented or suppressed to ensure sufficient ignition performance.

Abstract: Internal combustion engine according to the invention comprises an exhaust treatment apparatus provided in an exhaust passage, a burner apparatus provided upstream of the exhaust treatment apparatus for increasing exhaust temperature, and a variable mechanism for varying valve timing of an exhaust valve. The variable mechanism is controlled in such a manner that, when a flow amount of exhaust gas passing through the burner apparatus is equal to or more than a predetermined value, the exhaust valve opens in the middle of piston descending during an expansion stroke. When the exhaust valve is opened at this timing, high-temperature exhaust or combustion gas existing in combustion chamber at this time is sent to the burner apparatus, making it possible to increase atmosphere gas temperature of the burner apparatus. Therefore, even when flow amount of exhaust gas is increased to the predetermined value or more, sufficient ignition performance can be ensured.

Abstract: The present invention relates to production and packaging of rice-ball rolled in laver.A laver is wrapped in a packing sheet for blocking moisture and rice-ball is packed by said packing sheet. The rice-ball is rolled in said laver when stripping said packing sheet. The flavor of laver is prevented from being damaged by the moisture of said rice-ball even after a long time from its production. Moreover, said rice-ball in laver can be packed surely and cleanly for selling them at drive-in store or at a station.
