摘要： A mixing block to supply a throttle-able hydrogen and air mixture to an internal combustion engine includes a bore through the mixing block between an air intake side and an engine intake side. A slider chamber is disposed orthogonal to and intersecting the bore, where the slider chamber houses a movable slider biased to at least partially block the bore but throttle-able to overcome the bias and reduce blockage of the bore. A jet chamber is disposed parallel to and intersecting the slider chamber and extending away from the slider chamber a distance sufficient to accommodate a shaped needle, where the needle is connected to the slider on one side such that the needle moves within the jet chamber as the slider moves in the slider chamber.

摘要： A method for balancing a plurality of cylinders during operation of an internal combustion engine having a plurality of gas admission valves includes operating the internal combustion engine with a first common ignition timing for each of a plurality of cylinders. While operating with the first common ignition timing, a cylinder having an above-average knock level is determined, and an opening duration of the gas admission valve associated with this cylinder is reduced. This is repeated until the knock levels for all cylinders differ from each other by less than a predetermined amount. When the knock levels for all cylinders differ by less than the predetermined amount, the first common ignition timing is advanced to a second ignition timing.
