    摘要: Method and apparatus for removing contaminants from internal combustion engine exhaust gas recirculation cooler. The method feeds a portion of such exhaust gasses to an input end of an exhaust gas recirculation cooler with such gases flowing through the cooler to exit an output end of the cooler. The output end is at a lower elevation then the input end with gravitational forces being imparted to the contaminants. At least a portion of the contaminants exiting the cooler are collected in a trap. The exhaust gasses exiting the trap are returned to an intake manifold of the engine. Apparatus includes: a cooler for cooling the exhaust gasses having an input port for receiving a portion of such exhaust gasses and an output port for removing the cooled gasses; and a trap coupled to the output port for collecting particulates in the exhaust gasses passing to such trap from the cooler.
