Title:
COOLING DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/163052
Kind Code:
A1
Abstract:
A cooling device according to the present invention is equipped with: a container (112) having one gas inlet/outlet port; a cooler core (120) disposed inside the container (112); and a connection pipe (110) branching from an exhaust pipe (24) in an area between an exhaust valve and a catalyst and connecting the exhaust pipe (24) to the inlet/outlet port of the container (112). When V1 is the volume of the space between the branching point of the connection pipe (110) and a front end surface (122) of the cooler core (120) in the container (112), V2 is the volume of the container (112) past the front end surface (122) of the cooler core (120) as V2, and A is the ratio of the minimum pressure and maximum pressure indicated by the exhaust gas pressure when an internal combustion engine outputs its maximum torque, the container (112) and the connection pipe (110) are formed so as to satisfy the following relationship.
V1/(V1 + V2) < 1 - A
