Abstract
A supercharging system for an internal combustion engine includes an exhaust introduction passage for introducing exhaust gas from an internal combustion engine; an exhaust discharge passage for introducing the exhaust gas from the exhaust introduction passage and exhausting the exhaust gas to an exterior; a mixture part arranged between the exhaust introduction passage and the exhaust discharge passage, for changing internal pressure into negative pressure upon accelerating flowing velocity of the exhaust gas with a narrowed flowing passage set to have a smaller diameter than the exhaust introduction pipe; an absorption passage for mixing outside air and the exhaust gas inside the mixture part upon introducing the outside air with use of negative pressure into an inside of the mixture part; and an intake passage for taking out and returning a part of mixed gas mixed inside the mixture part to a side of the internal combustion engine.
