Abstract: No studies have been made regarding what kinds of refrigerants should be used in a refrigeration cycle device for a vehicle. An air conditioner (1) for a vehicle includes a refrigerant circuit (10) and a refrigerant that is sealed in the refrigerant circuit (10). The refrigerant circuit (10) includes a compressor (80), a first heat exchanger (85), which serves as a heat dissipater in a dehumidifying heating mode, an outside-air heat exchanger (82), a cooling control valve (87), and a second heat exchanger (86), which serves as an evaporator in the dehumidifying heating mode. The refrigerant is a refrigerant having a low GWP.

Abstract: A detection device acquires traveling information and identification information of a driver from a first device installed in a vehicle and acquires a vital sign and the identification information of the driver from a second device that monitors the vital sign. The detection device determines probability of detecting a predetermined event, based on the vital sign in proximity of a certain time, when the predetermined event is detected at the certain time based on the traveling information and outputs a determination result.

Abstract: An information providing apparatus includes a unit that presents an effectiveness of introducing a service of informing a driver during driving of information related to a point where hard braking is apt to happen, by comparing driving data when the service is provided and driving data when the service is not provided, and outputting a comparison result.

Abstract: A hole axis of a communication hole is placed at a location, which coincides with a translated location of a hole axis of a connector hole that is translated toward an axial distal end portion of a main body in an axial direction of the main body. In this way, with respect to a high pressure flow passage, which is bent by 90 degrees and extends through the connector hole, the communication hole and an axial flow passage, the amount of projection of a projecting portion at an inner side area of this bent, which is located on the inner side of the bent, is reduced.

Abstract: The invention has an object for improving response of a fuel injection device. A flow-in recessed portion and a flow-out recessed portion are formed at a press-contacting surface of a floating plate, which is movably accommodated in a pressure control chamber. A flow-in port and a flow-out port are formed at a pressure control surface of a valve body. The flow-in port is opened to the flow-in recessed portion, while the flow-out port is opened to the flow-out recessed portion. When the floating plate is moved upwardly and the press-contacting surface is brought into contact with the pressure control surface, the flow-in port is surely closed.

Abstract: A diesel engine in which a lubrication oil on the wall surface of the cylinder liner is prevented from being burned and diluted, and a smoke resulting from the local lack of air in the combustion chamber is also prevented from being generated. The diesel engine comprises a group injection hole nozzle 20 and a piston 110. A step 115 having a height gradually increased toward the radial outer circumference of the piston is formed over the entire circumference of the top surface 111 of the piston. Furthermore, a tilted part 115b is formed as the step surface of the step 115.

Abstract: In a diesel engine equipped with an injector 1 having a plurality of intersections between an axis line of the injector 1 and the axes of injection holes 10a bored in the injector 1, an air intake valve 25 is controlled so that it is closed at timing before a BDC (at timing when a piston comes to a bottom dead center) by an ECU 50, which controls the timing of closing the air intake valve 25 based on operating conditions of the engine.

Abstract: In a method for boring injection holes of an injector 1 having a plurality of intersections between an axis line of the injector 1 and the axes of the injection holes 10a bored in the injector 1, or so-called a group of injection holes 10, flat sections 10c, 10d, which are perpendicular to the injection holes 10a and include apertures of the injection holes 10a, are formed on boring portions of injection holes 10a. The boring portions are provided with recessed portions 10b and the recessed portions 10b are formed at the bottom thereof with flat sections 10c. Alternatively, the flat sections 10c, 10d are formed by cutting the boring portions, or by forging them.
