Abstract: A method for adjusting a valve lash in an internal combustion engine includes receiving a first signal generated by a sensor secured to the internal combustion engine, the first signal being indicative of a closing of a valve, receiving a second signal indicative of at least one of an engine speed of the internal combustion engine or a position of a camshaft of the internal combustion engine, and automatically determining an adjusted amount of lash associated with the valve based on the received first signal and the received second signal. The method also includes comparing the adjusted amount of lash to at least one predetermined threshold, and providing, in response to determining that the adjusted amount of lash is greater than the at least one predetermined threshold, a valve lash re-adjustment notification.

Abstract: An engine control module (ECM) having a plurality of driver banks is provided. Each of the driver banks is configured to drive a plurality of combustion control elements. The driver banks include two low side driver circuits and a high side driver circuit, the high side driver circuit in each of the plurality of driver banks being shared pairwise by two combustion control elements. Each one of said at least two low side driver circuits is respectively associated with the two combustion control elements. The ECM includes a field programmable gate array (FPGA) coupled to the plurality of driver banks and configured to provide firing signals to at least twelve high side driver circuits to simultaneously drive at least twelve combustion control elements respectively coupled to the at least twelve high side driver circuits.

Abstract: Techniques are described to smooth start a multilevel dual active bridge converter by pre-charging the capacitors present on the converter without requiring any additional hardware. Various phase shift angles determine the power delivered by the dual active bridge converter. By using the techniques, a predefined amount of time is reserved to pre-charge the capacitors until the capacitors reach a desired voltage after which time the smooth starting of the dual active bridge converter is initiated.
