摘要： A method of operating a cleaning process on a filter in a vehicle air intake, comprises passing air through the filter from an upstream side to a downstream side, and providing an exhaust duct having an inlet end adjacent the upstream side of the filter and an outlet end adjacent a cooling fan of the vehicle arranged to draw air through the exhaust duct from the inlet end to the outlet end. In a periodic cleaning subroutine, the rotational speed of the cooling fan is increased (110) from a first speed to a second speed, whilst a pulse of pressurised fluid is applied (112, 116) to a downstream side of the filter, and the exhaust duct carries away (114, 118) material dislodged from the upstream side of the filter by the applied pulse, before the rotational speed of the fan is reduced (120) to its original level. The fan may be replaced by alternative devices for drawing air through the exhaust duct.

摘要： A cooling unit for an agricultural vehicle, the cooling unit including: a grid for allowing air to enter the unit whilst limiting the ingress of debris into the unit, a heat exchanger for transferring heat from a coolant carried within the heat exchanger to air passing across the heat exchanger, a duct situated between the grid and the heat exchanger, a fan situated in the duct, the fan driven by a motor to move air along the duct and across the heat exchanger, a controller in communication with the motor to monitor the current drawn by the motor, wherein the fan is operable by the controller in a first direction to draw air through the grid and across the heat exchanger and in a second direction for a predetermined period of time upon the current drawn by the motor rising above a first predetermined value, and wherein the controller generates a heat exchanger blockage warning in the event that the motor current fails to drop below a second predetermined value upon the subsequent rotation of the fan in the first direction.
