Title:
INTAKE GAS COOLING DEVICE FOR SUPERCHARGED INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/046182
Kind Code:
A1
Abstract:
An intake gas cooling device (10) for a supercharged internal combustion engine, wherein a reservoir (30) which temporarily holds condensation water is provided in the lower portion of a low-temperature-side tank (26), and a water extraction pipe (32) is provided extending from the bottom of the reservoir (30) into the interior of an outlet pipe (28). The reservoir (30) is separated from an upper chamber (38) by an inner partition plate (36), and a water discharge opening (40) is provided in the inner partition plate (36). Baffle plates (44) are provided on the top of the inner partition plate (36). Condensation water is discharged into the reservoir (30) temporarily, and is extracted through the water extraction pipe (32), thereby preventing the condensation water from being carried away all at once. The reservoir (30) is separated from the upper chamber (38) by the inner partition plate (36), so the condensation water is not carried away all at once. Even if the condensation water accumulates on the inner partition plate (36), the baffle plates (44) prevent the condensation water from being carried away all at once. Thus, it is possible to prevent condensation water in supercharged air from flowing into the internal combustion engine all at once and causing the engine to malfunction.
