SPRAYING MEANS FOR CHARGE AIR MOISTURIZING SYSTEM IN INTERNAL COMBUSTION ENGINE

摘要

A supercharged air moisturizing device for an internal combustion engine is provided to accomplish maximum humidification by injecting mixture of a supercharged air and a moisturized air. A supercharged air moisturizing device for an internal combustion engine includes a supercharger(2), an expansion flow path(3), and an extension flow path(4). The supercharger is installed at the internal combustion engine. The expansion flow path and the extension flow path are installed at a rear end of the supercharger. A humidifying water is injected into the expansion flow path and the extension flow path to increase humidity of the supercharged air supplied into the expansion flow path and the extension flow path. A portion of the supercharged air is supplied into an auxiliary supercharger(21) to be compressed again, and the mixed with the humidifying water.
