ABSTRACT:
A diverter, apparatus and method of bypassing an exhaust gas recirculation cooler in order to selectively cool recirculated exhaust gas is disclosed. The diverter relies on the Coanda effect to direct the exhaust gas flow to the cooler or to a bypass around the cooler and thus preferred embodiments do not require a valve to be provided in the exhaust gas flow for this purpose. This simplifies the assembly of the diverter and apparatus and provides for a more reliable diverter compared to certain known systems.
