Patent ID: 8573144

Claim:
An exhaust conditioning system in combination with an agricultural implement and an internal combustion engine operatively connected to the agricultural implement for movement therewith across the ground, the system comprising: an exhaust duct in communication from the engine to the agricultural equipment so as to be arranged to communicate exhaust emissions from the engine therethrough; an impeller fan supported in communication with the exhaust duct so as to be arranged to draw a flow of exhaust emissions from the engine through the exhaust duct; a condenser comprising an exhaust passage coupled in series with the exhaust duct so as to be arranged to receive the exhaust emissions therethrough between the engine and the impeller fan; a condenser fan supported in proximity to the condenser so as to be arranged to direct cooling air across a surface of the exhaust passage; an exhaust temperature sensor arranged to sense a temperature of the exhaust; and a computer controller operatively connected to the exhaust temperature sensor and at least one of the condenser fan, the impeller fan or the engine so as to be arranged to controllably vary a rate of at least one of the condenser fan, the impeller fan or revolutions per minute of the engine responsive to the temperature of the exhaust emissions sensed by the exhaust temperature sensor to maintain the temperature of the exhaust emissions within a selected temperature range.
