    摘要： A method of regenerating a particulate filter in an apparatus comprising an internal combustion engine and a catalyst that employs urea as reductant for NOx is disclosed. The method comprises exposing the catalyst and particulate filter to a first, lower elevated exhaust temperature to remove urea deposits and/or stored hydrocarbon from the catalyst, and then exposing the catalyst and particulate filter to a second, higher elevated exhaust temperature to heat the particulate filter to decompose particulate matter in the particulate filter. In this manner, damage caused to the catalyst due to the decomposition and reaction of urea deposits and/or oxidation of stored hydrocarbon during particulate filter regeneration may be avoided.

    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.
