PROBLEM TO BE SOLVED: To provide a supercharging system of an internal combustion engine that prevents performance of a turbocharger from deteriorating, prevents condensate water in a turbine housing from scattering at the time of cold start of the internal combustion engine, and prevents a sensor from being broken by water immersion.SOLUTION: In an inner peripheral part of a turbine housing 13, in an installation attitude of the turbine housing 13, a rail groove 21 extending in a predetermined length over a circumferential direction of the turbine housing 13 is provided below a gravity direction of the inner peripheral part of the turbine housing 13. A water absorption member 20 is housed in the rail groove 21. Also, the rail groove 21 has holding surfaces 18a, 19a holding the water absorption member 20, and holds the water absorption member 20 by the holding surfaces 18a, 19a. |
