摘要： The fuel cell system includes a fuel cell, a first injection device associated with a supply of a fuel to the fuel cell, and a second injection device provided on an upstream side of the first injection device in a fuel flow passage from a fuel storage unit to the first injection device. The first and second injection devices switch a flow passage extending downstream from the fuel flow passage, between a first flow passage via the first injection device and second flow passage via the second injection device. The second injection device operates at a lower frequency than the first injection device during an operation of the fuel system.

摘要： A pendulum type mount system includes a pair of upper mounts that mount upper portions of a powerplant unit on a vehicle body, and a pair of first and second lower torque rods. The first and second lower torque rods are located on opposite sides to each other with respect to a reference plane including a gravity center of the powerplant unit. A first spring constant of the first lower torque rod is not smaller than a second spring constant of the second lower torque rod. A distance between a first plane including the first lower torque rod and the reference plane is not larger than a distance between a second plane including the second lower torque rod and the reference plane.

摘要： A control method of an electric vehicle using one or a plurality of motors as a traveling drive source, includes: a motor torque command value calculating step that calculates a motor torque command value; an angular velocity detecting step that detects an angular velocity correlating with a rotation speed of a drive shaft which transmits a drive force of the motor to a drive wheel; a disturbance torque estimating step that estimates a disturbance torque acting on the motor based on the motor torque command value and the angular velocity; a limiting torque setting step that sets a limiting torque corresponding to the disturbance torque in a manner that a slipping rate of the drive wheel does not exceed a first predetermined value; and a motor torque limiting step that limits the motor torque command value using the limiting torque.

摘要： The nozzle for cold spray (25) used in a cold spray apparatus (2) is configured to include a tubular nozzle main body (252) and a cooling jacket (253) that surrounds the nozzle main body (252) to form a flow path (25e) for refrigerant (R) between the nozzle main body (252) and the cooling jacket (253). The cooling jacket (253) is provided with a seal retaining portion (253c) that retains an O-ring (253b) for the flow path (25e). The seal retaining portion (253c) and the nozzle main body (252) are joined in a socket-and-spigot joint fashion.

摘要： A rotating electrical machine includes a cylindrical housing having a flow path configured to allow a refrigerant to flow therethrough, an inlet configured to allow the refrigerant to flow into the flow path, and an outlet configured to allow the refrigerant to flow out of the flow path. The flow path being formed so as to spirally surround a circumferential surface of the housing. The flow path includes: a first flow path that is formed along one end surface of the housing and formed such that a width along the circumferential surface increases along a flow direction of the refrigerant from the inlet; and a second flow path that is formed along the other end surface of the housing and formed such that a width along the circumferential surface decreases toward the outlet along the flow direction of the refrigerant.

摘要： A control method is performed to control a traction device of a motor vehicle having an internal combustion engine that includes a plurality of cylinders. Each of cylinders has at least one air intake valve, at least one exhaust valve for the combustion gases generated by the internal combustion engine, and a fuel injector. A treatment device is provided for the combustion gases that is active from an actuation temperature. The treatment device is placed downstream of the exhaust valve. The traction device includes an electrical heater for heating the combustion gas treatment device. The traction method further compares a temperature of the combustion gas treatment device with an actuating threshold temperature and actuates the electrical heater and stopping a fuel supply being supplied to one or more of the cylinders as long as the temperature of the combustion gas treatment device is below the actuating threshold temperature.
