摘要： An assembly for a fuel injector that includes a piston that is decoupled from the needle of a needle valve. The piston is slidingly positioned in a disk bore. The portion of needle in the disk bore is smaller than the disk bore so as to prevent the disk bore from interfering with movement of the needle between seated and unseated positions. During periods of operation, the upper surface of the piston is engaged by a control volume of fuel that pushes the needle toward a seated position, while the needle pushes in an opposing direction against a lower surface of the piston. The surface area of the piston acted on by the control volume is larger than the upper portion of the needle that is typically acted upon by the control volume, thereby providing a larger force on the piston that keeps the needle in a seated.

摘要： An exhaust after-treatment system is described. Generally speaking, the system includes separate primary and secondary NOx reducing systems for delivering reductant (e.g. urea and ammonia) to an exhaust stream, a sensor system for determining relevant operating conditions and an electronic control module for activating the reducing systems. The two NOx reducing systems include flow control modules coupled to the electronic control module. Methods for reducing NOx in an exhaust stream are also described. Generally speaking, the methods include the steps of determining a need for NOx reduction in an exhaust stream, determining temperature of exhaust stream, and injecting at least one of a primary reductant and a secondary reductant into the exhaust stream based on the determined temperature of the exhaust stream. Typically, the primary reductant comprises urea and the secondary reductant comprises ammonia.

摘要： A controller for a vehicle pneumatic system loads a compressor responsive to engine power absorption by the engine and air storage facility air pressure readings up to a pressure limit. The controller is responds to power demand on the engine in excess of an engine speed related global maximum and air pressure readings down to a global minimum for unloading the compressor. The controller provides for loading and unloading the compressor to maintain storage facility pressure within an operating maximum and an operating minimum which lie between the global maximum and global minimum pressures. The controller responds to air pressure readings reaching or falling below the global minimum for loading the compressor and to air pressure readings reaching or exceeding the global maximum for unloading the compressor.

摘要： A premixed charge of air and a low reactivity fuel is created in a combustion chamber space by the time at which a piston comes substantially to top dead center at which time a high reactivity fuel is directly injected into a central zone of the combustion chamber space which is bounded partially by a central bowl cavity in the piston head which is itself surrounded by an upright intermediate wall. The high reactivity fuel combusts by conventional diesel combustion and creates a flame front which propagates into an outer zone of the combustion chamber space which is bounded partially by the upright intermediate wall and an outer bowl cavity in the piston head to initiate combustion of the premixed air-fuel charge in the outer zone of the combustion chamber space.
