PROBLEM TO BE SOLVED: To provide a metal clip for fixing a vehicle accessory capable of improving the yield of a metal sheet required for forming metal clips and reliably and temporarily fixing the accessory to an interior material, and a vehicle accessory mounting structure using the same. SOLUTION: The metal clip 10 for fixing the vehicle accessory comprises a first V-shaped piece 33 which is bent substantially in a V-shape when viewed from the side while an edge of each piece forms a mounting part 34 to be engaged with a base part 12 of the accessory, and an engagement part 36a to be engaged with a mounting hole of a vehicle body panel is provided in the middle of each piece, an extension part 37 extending in the direction of a folding line 32 from a valley bottom part 31 of the first V-shaped piece 33, and a second V-shaped piece 38 which extends in the direction across the extension part 37 from both sides of the extension part 37, is folded in a V-shape with the extension part 37 at the valley bottom part 31, and temporarily fixes the accessory by engaging an end 38a with a hole 51 of an interior material 50.

PROBLEM TO BE SOLVED: To provide a turbocharger, capable of suppressing both the deterioration of turbine efficiency and the dispersion of gas flow rates between scroll passages.SOLUTION: The turbocharger is provided with a turbine housing a turbine wheel 32. The turbine includes a first scroll passage 33 and a second scroll passage 34 extending in a spiral form on the outer periphery of the turbine wheel 32. A center housing in which a shaft integrally fixed to the turbine wheel 32 is rotatably supported is provided at a position adjacent to the turbine. Of angles formed, in a cross section of the turbine at a rotation axis L1 of the turbine wheel 32, by a line LB showing the extending direction of each scroll passage 33, 34 and the rotation axis L1, the angle ω including the front edge of the turbine wheel 32 is set to be increased toward the downstream side of the scroll passages 33, 34 (Fig.4 [A]→Fig.4 [B]→Fig.4 [C]→Fig.4[D]).

PROBLEM TO BE SOLVED: To promote warming-up of in an internal combustion engine at the start of the engine while preventing a partial boiling of an antifreeze liquid in proximity of an combustion chamber of the internal combustion engine even when a concentration of the antifreeze liquid varies.SOLUTION: A control device 91 promotes the warming-up for controlling a rotation speed of a pump 23 so that a discharge rate of the antifreeze liquid is restricted when a temperature of the antifreeze liquid θ is lower than an upper limit temperature θc. Moreover, the control device 91 calculates a primal temperature θb that becomes a higher one as a concentration of the antifreeze liquid Wd gets higher based on the concentration of the antifreeze liquid Wd, and updates the upper limit temperature θc so that the deviation between the upper limit temperature θc that is presently set, and the primal temperature θb is reduced.
Abstract:
PROBLEM TO BE SOLVED: To provide a cooling devic for an internal combustion engine capable of differentiating the operation timing of each thermostat while achieving the communalization of thermowax or the like of each thermostat.SOLUTION: In a two-system cooling device having first and second thermostats, the first thermostat 4 has a guide member 46 for changing the streamline of cooling water flowing in from a bypass flow passage 1f to a heat-sensing cylinder 41a. The second thermostat has the same constitution as that of the first thermostat 4, and its arrangement posture has the phase difference of 180° to the arrangement posture of the first thermostat 4. Thus, in the second thermostat, the flow of cooling water from a pump flow-out passage to a head side flow passage is not blocked by the guide member. Thus, the operation timing of the first thermostat 4 can be expedited and the operation timing of the second thermostat can be delayed.
