Forced convection EGR cooling system

摘要

A method of cooling recirculated exhaust gas from an exhaust manifold (27) of an engine (16) upstream of an intake manifold (29), the method including passing the recirculated exhaust gas from the exhaust manifold through a heat exchanger (36), and convectively forcing ambient air flow through the heat exchanger with at least one fan (58) attached to the heat exchanger. The method also includes the step of passing the cooled recirculated exhaust gas to the intake manifold (29).
