Abstract: A tilt rate compensating implement system and method utilizes first and second sensors for sensing the position of the rod end portion (32, 34) of first and second implement lift jacks (28, 30). A controller calculates a tilt angle of the implement (12) based on a difference in the amount of extension of the lift jacks (28, 30). An inclinometer senses an angle of the frame relative to a predetermined plane and a tilt rate sensor senses the rate of change of the frame angle relative to said plane. A corrected frame angle based on signals from the inclinometer and tilt rate sensors is combined with the implement tilt angle to provide a corrected implement tilt angle. A display device displays the corrected implemented tilt angle. The controller compares the corrected implement tilt angle to the desired implement tilt angle and actuates a fluid operated system to move a tilt jack in response to a difference between the desired and corrected implement tilt angles. The tilt angle control system is particularly suited for use on a bulldozer.

Abstract: The present invention is particularly well suited for purifying exhaust from relatively large lean burn diesel engines. A computer controlled injector (20) intermittently injects an optimal amount of NOx reducing fluid into the exhaust passageway (11) from the engine (12). The optimal amount corresponds to an amount that will achieve optimal NOx reduction rates for the given engine operating condition and exhaust temperature. A computer (16) periodically senses the engine operating condition and the exhaust temperature, and calculates the appropriate injection amount. With appropriate deNOx and oxidation catalysts located downstream from the injector (20), the exhaust purification system (10) of the present invention has the ability to greatly reduce NOx content of the exhaust while maintaining HC emissions at acceptable levels.

Abstract: An improved hydraulically-actuated fluid injector system (10) comprises a hydraulically-actuated fuel pressurization member (74), a fluid storage chamber (94), and a direct-operated check (76). Pressurization of fluid in the storage chamber (94) begins before the start of fluid injection. Fluid injection begins by hydraulically unbalancing the check (76). Fluid injection ends by hydraulically balancing the check (76) to allow a biasing device (78, 82) to close the check (76). Preferably, actuating fluid (32) that is spilled from the fuel pressurization member (74) (to end fuel injection) is communicated to a hydraulic motor (178) which drives a source of pressurized hydraulically-actuating fluid (32). The present invention provides improved control of several fluid injection parameters, including higher peak fluid injection capability and less fluid injection pressure drop at the end of injection, resulting in improved engine performance and lower emissions, noise, and wear. The present invention also improves efficiency of operation due to the above hydraulic energy recovery feature.

Abstract translation: 改进的液压致动流体喷射器系统（10）包括液压致动燃料加压构件（74），流体储存室（94）和直接操作支架（76）。 储存室（94）中的流体加压在液体注入开始之前开始。 流体注射开始于液压不平衡支架（76）。 流体注射通过液压平衡支票（76）终止，以允许偏压装置（78,82）关闭支票（76）。 优选地，从燃料加压构件（74）溢出（以终止燃料喷射）的致动流体（32）被传递到驱动加压液压致动流体源（32）的液压马达（178）。 本发明提供了几种流体注入参数的改进控制，包括较高的峰值流体注入能力和在注射结束时较少的流体注射压降，从而改善发动机性能并降低排放，噪音和磨损。 由于上述液压能量回收特征，本发明还提高了操作效率。

Abstract: During operation of an internal combustion engine, structures adjacent the piston top ring turn around position and the exhaust port are exposed to high temperatures. In order to improve cooling around these adjacent structures, the heat transfer coefficient must be increased. In this manner, energy around the top ring turn around position on the cylinder liner and around the exhaust seat can be transferred through a cooling liquid and away from the adjacent structures. The present invention enhances the cooling capability within an engine (10) by utilizing a flow controlling device (60) disposed between a cooling liquid inlet chamber (46) and a cylinder liner (27). The flow controlling device (60) has a plurality of orifices (70) therein. A cooling liquid from a pressurized source is communicated to the inlet chamber (46) and passes through the plurality of orifices (70) to impinge a predetermined peripheral portion of the cylinder liner (27) adjacent an exhaust port (38). Due to the small size of the orifices (70), the velocity of the cooling liquid is increased as it passes therethrough. The increased velocity of the cooling liquid and the subsequent impingement upon a required, selected portion of the cylinder liner (27) increase the overall cooling effectiveness.
