Abstract
An exhaust conditioning system for use with a tractor towing an air seeding implement comprises an exhaust duct arranged to communicate exhaust emissions from the engine of the tractor to the seed fan of the air seeding implement. A condenser receives the exhaust emissions of the exhaust duct therethrough between the engine and the seed fan. A condenser fan cools a surface of the condenser. A computer controller controllably varies a rate of at least one of the condenser fan, the seed fan or revolutions per minute of the engine responsive to a sensed temperature of the exhaust emissions to maintain the temperature of the exhaust emissions within a selected temperature range and such that the exhaust emissions are arranged to influence germination of the seeds either by humidity, oxidised organic matter or bio-char.
Claims20
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.
An exhaust conditioning system in combination with an agricultural implement and an internal combustion engine operatively connected to the agricultural equipment, the system comprising:
- an exhaust duct in communication with the engine so as to be arranged to receive exhaust emissions from the engine;
- a condenser comprising:
- an exhaust passage coupled in series with the exhaust duct so as to be arranged to receive the exhaust emissions therethrough;
- a primary cooling passage in proximity to a first portion of a surface of the exhaust passage so as to be arranged to direct cooling air across the first portion of the surface of the exhaust passage;
- an auxiliary cooling passage in proximity to a second portion of the surface of the exhaust passage so as to be arranged to direct cooling air across the second portion of the surface of the exhaust passage;
- and
- a condenser fan in communication with the primary and auxiliary cooling passages so as to be arranged to blow the cooling air through the respective cooling passages;
- an exhaust temperature sensor arranged to sense a temperature of the exhaust;
- and
- a computer controller operatively connected to the exhaust temperature sensor and the condenser fan so as to be arranged to controllably vary an amount of cooling air received in the primary and auxiliary cooling passages respectively responsive to a temperature of the exhaust emissions sensed by the exhaust temperature sensor to maintain the temperature of the exhaust emissions within a selected temperature range.
