Abstract: A method and apparatus for estimating internal brake energy in a fluid cooled brake (16) of the type used in large work machines from easily sensed machine operating parameters. The temperature of the coolant is sensed before and after it passes through the brake (16). The coolant flow rate through the brake (16) is determined from one or more additional sensed parameters (34), for example engine speed. The sensed parameters (34) are used in a thermodynamic model of the brake (16) which generates estimates of internal brake temperature (TEIB) and the amount of power absorbed by the brake (BRKP). Signals representing TEIB and optionally BRKP are generated to provide indications of brake operation and/or health. The model is executed on a digital computer (36) either on-board the vehicle (12) or at a remote location.

Abstract: A hydraulically powered rotary actuator (32) for rotating a first portion (14) of a work machine (10) relative to a second portion (12) of the work machine (10) has inner and outer rings (36, 96, 38, 98) enclosed by first and second cover plates (42, 104, 44, 106). The inner and outer rings (36, 96, 38, 98) are spaced apart to define a hydraulic power chamber (56, 98) to which pressurized fluid is supplied to rotate one of the inner or outer rings (36, 96, 38, 98). The first portion (14) of the work machine (10) is connected to the rotatable ring (36, 96) and rotates with it. A large diameter bearing assembly (40, 110) rotatably supports the rotatable ring (36, 96) and the first portion (14) of the work machine (10). Most prior work machines with rotatable car or upper structure require large expensive components including gear reduction assemblies, a hydraulic motor, and large diameter swing gear. The subject actuator simplifies the construction by eliminating many of the prior components.

Abstract: The present invention is particularly applicable to lean burn engines that produce exhaust containing insufficient amounts of unburned hydrocarbons to satisfactorily reduce NOx emissions without undermining engine performance. In the exhaust purification system (10), ethanol or another suitable hydrocarbon (19) is injected into the exhaust stream at an appropriate location between the engine and the catalytic converter (12). A deNOx catalytic converter (22, 122, 222) is positioned within the exhaust downstream from the ethanol injection point. The combination engine application, ethanol injection and suitable deNOx catalyst combine to reduce NOx to satisfactory levels without producing significant amounts of undesirable secondary nitrogen containing compounds. An oxidation catalytic converter (24, 124, 224) is positioned in the exhaust downstream from the deNOx catalytic converter (22, 122, 222). The oxidation catalyst serves to convert any remaining unburned hydrocarbons (19) into carbon dioxide and water. At the same time, only small amounts of secondary nitrogen compounds are converted back into NOx compounds upon passage through the oxidation catalyst. The end result being an overall reduction in both HC and NOx compounds particularly for lean burn engines to satisfactory levels.

A first digital three-dimensional model (104) of the desired site geography, and a second digital three-dimensional model (106) of the actual site geography are stored in a digital data storage facility (126). The machine (10) is equipped with a position receiver to determine in three-dimensional space the location of the machine (10) relative to the site (12). A dynamic database (400) receives the machine position information, determines the difference between the first and second site models (104, 106) and generates representational signals of that difference for directing the operation of the machine (10) to bring the actual site geography into conformity with the desired site geography. In one embodiment, the signals representing the machine position and the difference between the first and second site models (104, 106) used to generate an operator display (108) which is updated in real time. Alternately, the signals representing the difference between the first and second site models (104, 106) can be supplied to automatic machine controls (128) for autonomous or semi-autonomous operation of the machine (10).
