摘要
A machine 10 includes an internal combustion engine 50 disposed within an engine compartment 26 and supported on a machine frame 14. An exhaust stack 102 has an inlet 104 fluidly connected to an exhaust manifold 80 of the internal combustion engine 50 and an outlet 230 in fluid communication with ambient air. A diesel particulate filter 54 is disposed along the exhaust stack 102, and the machine 10 includes an active regeneration system 95 for regenerating the diesel particulate filter 54. A cooling package 58 including at least one heat exchanger 120 and a blower fan 124. The blower fan 124 is configured to blow cooling air from the engine compartment 26 sequentially through the at least one heat exchanger 120 and an outlet 232 of the cooling package 58. Exhaust gas exiting the exhaust stack outlet 230 is mixed with the cooling air exiting the cooling package outlet 232 in a high temperature zone 234 surrounding the exhaust stack outlet 230 to form a fluid mixture. An electronic control module 97 is in control communication with the active regeneration system 95 and includes a regeneration control algorithm operable to detect a speed of the blower fan 124.
