  • Patent number: 10788396
    Abstract: A calibration system and method for a spark ignition engine of a vehicle involve artificially weighting engine dynamometer data in high engine load regions and using it to generate training data for an artificial neutral network (ANN). A plurality of ANNs are trained using the training data and the plurality of ANNs are then filtered based on their maximum error to obtain a filtered set of trained ANNs. A statistical analysis is performed on each of the filtered set of trained ANNs including determining a set of statistical metrics for each of the filtered set of trained ANNs and then one of the filtered set of trained ANNs having a best combination of error at high engine loads and the set of statistical error metrics is then selected. Finally, an ANN calibration is generated using the selected one of the filtered set of trained ANNs.

  • Patent number: 10786842
    Abstract: A method of forming a finished stamped product includes positioning a blank on a blank holder between an upper die and a lower die, inserting a movable wedge block between the blank holder and the upper die to establish a first binder gap, and while the movable wedge block is inserted, performing a first strike of the blank by lowering the upper die a first distance to contact and partially form the blank, the movable wedge block limiting downward movement of the upper die relative to the lower die. After the first strike, withdrawing the movable wedge block to establish a second binder gap between the blank holder and the upper die, and while the movable wedge block is withdrawn, performing a second strike of the blank by lowering the upper die a second distance to finally form the blank into the finished product.

  • Patent number: 10781742
    Abstract: A liquid drain valve assembly for a charge air cooler includes a valve housing configured to couple to the charge air cooler, the valve housing having a condensate inlet configured to receive condensate from the charge air cooler, and a condensate outlet, a valve mechanism slidingly disposed within the valve housing and configured to selectively close the condensate inlet and the condensate outlet to facilitate preventing charge air from leaking during condensate draining, and a diaphragm assembly disposed within the valve housing and configured to selectively engage the valve mechanism to selectively open the condensate inlet and the condensate outlet to drain condensate from the charge air cooler when the charge air cooler is in a boosted condition and isolated from the atmosphere.
