摘要： PROBLEM TO BE SOLVED: To sufficiently remove metal ions by a metal ion removal means 16 even if fuel having high kinematic viscosity is used, in a fuel supply system 1.SOLUTION: This fuel supply system 1 includes a heating means 18 heating fuel, a cooling means 19 cooling the fuel, a temperature detection means 20 detecting fuel temperature, and a kinematic viscosity detection means 21 detecting kinematic viscosity of the fuel. An ECU 8 is provided to operate the heating means 18 and cooling means 19 according to a detection value of the fuel temperature and a detection value of the kinematic viscosity of the fuel. Thereby, when the fuel temperature is low and the kinematic viscosity of the fuel is high, the heating means 18 is turned on to raise the fuel temperature and also to reduce the kinematic viscosity of the fuel. As a result, even if a kind of fuel having high kinematic viscosity of the fuel and low fluidity is used, fluidity is certainly increased and the fuel is sufficiently dispersed and permeated into the metal ion removal means 16, thereby removing the metal ion.

摘要： PROBLEM TO BE SOLVED: To solve a problem that, since a conventional EGR control valve employs an expensive PTFE seal as condensed-water intrusion prevention means for a bearing, the number of part items and man-hours become large, thus causing a cost increase.SOLUTION: An EGR control valve has at least one or more radial holes 71 for leveling a pressure difference between an A-point and a B-point around an output shaft 5 at a first protrusive shaft part 41 of the output shaft 5 which forms a clearance part 62 between a throttle wall 65 of a hosing 4 and itself, or at a large-diameter shaft part 43. By this constitution, the pressure difference in a shaft circumferential direction at the clearance part 62 formed between an internal peripheral of the throttle wall 65 of the housing 4 and an external periphery of the first protrusive shaft part 41 of the output shaft 5 is eliminated. As a result, even if the expensive PTFE seal is abolished, condensed water does not intruded into a bearing hole 61 from passage holes 22, 23 of the housing 4.
