Cold charge duct for air charging cooler to cool charging air in e.g. petrol engine, of vehicle, has separator formed to flush with innermost surface of wall, and condensate traps provided in duct behind intercooler or in front of manifold

摘要

The duct (200) has an exterior wall defining a passage, which is formed for conducting air from a turbo supercharger to an internal combustion engine (10). A separator is formed to flush with an innermost surface of the exterior wall. Apertures of the exterior wall are formed by a section in the exterior wall. The separator comprises a curved edge that intersects an outermost surface of the exterior wall and another curved edge that intersects the innermost surface. Condensate traps (204) are provided in the duct behind an intercooler (205) or in front of an engine intake manifold (22).
