摘要： A bootup device and method for an application program on a mobile equipment to improve the bootup speed of the application program on the mobile equipment. The bootup device has an application management module, that boots up a virtual machine module based on the application program to be run. A virtual machine module, loads codes of the application program and Just in Time (JIT) compilation results of a bootup process of the application program into a memory, search, in the JIT compilation results, for local JIT compiled codes corresponding to the bootup process code segment to be executed, and executes the found local JIT compiled codes when executing each bootup process code segment of the application program. A storage management module, store and reads the codes of the application program and the JIT compilation results obtained from the JIT compilation of the bootup process of the application program.

摘要： A diesel exhaust aftertreatment system and method are provided. The system includes a lean NOx trap for reducing NOx and a transition metal-exchanged zeolite booster catalyst positioned downstream from the lean NOx trap for further reducing NOx. The lean NOx trap includes a NOx adsorbent material and one or more platinum group metals, and has a platinum group metal loading of less than about 90 g/ft3. The aftertreatment system provides high NOx conversion over a broad temperature range without the use of ammonia as a major reductant.

摘要： The reduction of a NOx trap upon engine shutdown is disclosed. One disclosed embodiment comprises detecting an engine shutoff, determining an engine stop position, and creating a reductive environment in the exhaust conduit upstream of the lean NOx trap at a time based upon the determined engine stop position. The creation of a reductive environment in the exhaust conduit upstream of the lean NOx trap may help to at least partially reactivate the lean NOx trap during engine shutoff.
