Method for on-line adaptation of engine volumetric efficiency using a mass air flow sensor

InactiveUS20090049897A1Simplifies initial calibration processImproves crank-to-run air flow calculationInternal-combustion engine testingElectrical controlStable stateProcess adaptation
An electronic engine controller is configured to execute a process of adapting a base value of the volumetric efficiency of an engine through the addition of a correction value of the volumetric efficiency. The process includes comparing an estimated mass air flow value calculated using a speed-density equation, with an actual mass air flow value measured by a mass air flow (MAF) sensor. A percentage error of the estimated mass air flow value as compared to the actual mass air flow value is calculated. When the percentage error indicates that the air flow is at steady state, then the process updates the VE correction value, by integrating the percentage error. The new correction value, thus computed, is then stored in a cell of an array corresponding to the current engine operating condition. The process is configured to add the correction value to the corresponding base value to produce an updated value of the VE, valid for that operating condition. The process accommodates changes in the volumetric efficiency of the engine due to part aging and deposit build-up over time, among other things. The updated VE value may then be used for mass air flow estimation and accordingly for fueling control as well.

Method and apparatus for performing cell reselection for supporting efficiently hierachical cell structures

A method for performing a cell reselection in a system comprised of a hierarchy of cells, wherein cells of one layer of the hierarchy have a size that differs from cells of another layer of the hierarchy. The method includes steps of (a) identifying to a user equipment a layer to which individual cells in a neighbor cell list are associated; (b) when performing neighbor cell measurements for reselection purposes, avoiding a measurement of cells in the list that are larger than a current serving cell unless a Cell Selection (S) parameter falls below a search threshold parameter (Ssearch), and is greater than zero; and (c), if S is less than or equal to zero, and no cell reselection to a better cell is in process, beginning a measurement of neighbor cells without regard for their hierarchical level. If the user equipment has made cell reselection to N different cells on the same hierarchical layer within a time Tmax, the user equipment initiates a reselection procedure for larger neighbor cells. This procedure accommodates user equipment that is moving at a relatively high speed through the cells. If the user equipment locates a larger cell, which fulfills cell reselection criteria Sn > 0 and Qn > Qs+Qoffsets,n+Qhyst for a period of time Treselection, cell reselection to the larger cell is made. Furthermore, if the user equipment performs a cell reselection to the larger cell, the user equipment does not attempt to reselect to a smaller cell within a time X, unless an immediate cell evaluation is triggered, wherein the time X can be pre-specified, or can be set by the network.

Effluent treatment process

According to the invention there is provided a tertiary effluent treatment process for reducing the phosphate levels in effluent. The process comprises the steps of delivering effluent from a wastewater treatment plant to a primary filter, delivering the filtered effluent to a series of two or more phosphate removal filters, delivering the filtered phosphate-depleted effluent to a treated water tank as treated water, delivering the filtered phosphate-depleted effluent from the treated water tank to a discharge tank as treated water; and, discharging the treated water from the discharge tank as required. Each phosphate removal filter comprises a plurality of polymer-based beads having nano-particles of iron oxide coated thereon. The advantage of using a series of two or more phosphate removal filters is that the process can deliver a final effluent containing specific pre-determined levels of phosphate that may be as low as 0.01 mg/L of effluent, but will in all cases be below 1 mg/L. The series of two or more filters also allow the process to accommodate variations in the phosphate content of the effluent without affecting the level of phosphate in the discharge, and, the system can be retro-fit to the end of any type of existing waste water treatment plant or can be integrated into a new facility.
