  • Method of removal of engine exhaust from a work machine and system thereof
    Patent number: 10465595
    Abstract: An apparatus and method of cooling an engine exhaust generated by an engine of a work machine having a hydraulically operated implement. The work machine includes an emission control system and a cooling system having an oil cooling system configured to cool an oil of a hydraulic system and an engine cooling system configured to cool an engine coolant circulating through the engine. An exhaust pipe, coupled to the emission control system and configured to direct engine exhaust, includes an outlet disposed in a space located between an oil cooler of the oil cooling system and a radiator of the engine cooling system. An air displacement device is configured to draw air into and away from the oil cooler and the radiator and to draw the exhaust from the exhaust pipe. Exhaust from the exhaust pipe is drawn past the oil cooler and the radiator to cool the exhaust.
