20120036833 | Scavenging Vacuum Pressure Provisioning with Exhaust Treatment - In one embodiment, a method that includes collecting particles from an intake flow of air for a diesel engine; removing the particles collected using scavenging vacuum pressure and without adding exhaust restriction; and treating combustion products of the diesel engine. | 02-16-2012 |
20120036843 | AIR FILTER ASPIRATION AND ASPIRATION FAN DRIVE FOR USE WITH EXHAUST TREATMENT - In one embodiment, a system includes: a diesel engine having an intake and an exhaust; an exhaust treatment system communicating with the exhaust and operative to treat combustion products of the engine; an intake treatment system communicating with the intake and having an air filter assembly operative to remove particles from a flow of air and to provide the flow of air to the engine; and an aspiration fan assembly having a fan mechanically driven by the engine to produce scavenging vacuum pressure, the aspiration fan assembly being operative to apply the scavenging vacuum pressure to the air filter assembly to remove particles collected in the air filter assembly. | 02-16-2012 |
20120247711 | PUSHER AIRFLOW FOR WORK VEHICLE COOLING SYSTEM - Overhead pushed airflow for a cooling system of a work vehicle. In one embodiment, a cooling includes an interior defined by upstream faces of heat exchangers. An air mover pushes ambient air downward through said cooling box from overhead of the work and across the heat exchangers. | 10-04-2012 |
20120247712 | COOLING PACKAGE ASSEMBLY FOR WORK VEHICLES - A cooling package assembly for a work vehicle. A plurality of heat exchangers cooperate with one another to define an interior of a cooling box. Single pass airflow is pushed across the heat exchangers. In one embodiment, the heat exchangers cooperate with one another to define a v-shape. | 10-04-2012 |
20120247729 | AIR MOVER REVERSING FOR WORK VEHICLE COOLING PACKAGE - A method for reversing an air mover to remove debris from a cooling system of a work vehicle. In one embodiment, the largest required fan speed for cooling the engine coolant, hydraulic oil and the charge air is used as the set point speed for a fan. The fan is operated at the set point speed to generate airflow across each of the heat exchangers. Multiple conditions are evaluated for reversing the direction of the fan. | 10-04-2012 |
20120247738 | DEBRIS PASSAGEWAY FOR WORK VEHICLE COOLING PACKAGE - A debris passage for a cooling box of a work vehicle. Airflow is provided into the cooling box from the exterior environment. A plurality of heat exchangers transfer heat into the airflow. The debris passage is defined between opposing heat exchangers to permit debris to pass from the airflow to the exterior of the cooling box. In one embodiment, the debris passage is underneath an air mover and is substantially vertical. | 10-04-2012 |
20120247752 | CONTROLLER FOR WORK VEHICLE COOLING PACKAGE - A controller and method for operating an air mover for a cooling system of a work vehicle. In one embodiment, engine coolant, hydraulic oil and charge air temperature data is measured. The temperature data is reconciled by using the largest required fan speed as the set point speed for cooling the heat exchangers with airflow. An air mover is operated at the set point speed to generate airflow across each of the heat exchangers. | 10-04-2012 |
