The present application relates to the technical field of separators, and provides a composite separator, a preparation method therefor, and a use thereof. The composite separator comprises a porous layer. The porous layer comprises an organic polymer resin, inorganic particles, and polymer fibers, the polymer fibers being polymer fibers modified with hydrophilic groups. In the present application, by adding polymer fibers into the porous layer, mechanical support is provided to the porous layer, such that the separator is resistant to bending, thereby improving the mechanical strength of the separator. In addition, hydrogen bond interactions are formed between the hydrophilic groups modified on the polymer fibers and the inorganic particles. Considering also the strong interactions between the polymer fibers and the organic polymer resin, this arrangement helps to fix the inorganic particles within the organic polymer resin, thereby effectively reducing detachment of inorganic particles from the porous layer. As a result, the separator has good air tightness, which helps to maintain the stability and safety of the separator.

0000 An enhanced control of hydrogen injection for internal combustion engine system and method providing greater real-time control of injection of hydrogen from a hydrogen generator, providing a further increase in performance and decrease in emissions of the engine of the motor vehicle. Initial values for parameters defining the optimal percentage amount or pressure of oxyhydrogen to be injected when the engine load is equal to one of several defined levels are entered and then interpolated to produce a curve specifying the amount of oxyhydrogen to be injected at any given engine-load level. Further adjustments to the load-related oxyhydrogen amounts are made for different engine operating temperatures in relation to different engine loads, and for different ambient air pressures related to altitude in relation to different engine loads. The initial values and adjusted values will be different for different engine types and sizes, different fuel types and grades, and other characteristics. The enhanced control of hydrogen injection for internal combustion engine system and method takes account of these engine-specific and operation-specific differences to provide an optimum amount of oxyhydrogen injection across a range of operating and ambient conditions.
