Abstract: 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.

Abstract: An uneven surface assistance device is disclosed including a first leg assembly and a second leg assembly having a length different. The assemblies are connected directly or indirectly to a supporting platform and are movable with respect to the supporting platform between a first lockable position orthogonal to the supporting platform and a stored position parallel to the supporting platform. The device further includes a transverse support connected to the supporting platform generally in between the first leg assembly and the second leg assembly. The support connects to a first arm connected to the first leg assembly where the first arm is parallel to the supporting platform when the first leg is in the stored position and the support further connects to a second arm connected to the second leg assembly where the second arm is parallel to the supporting platform when the second leg is in the stored position.

Abstract: A propulsion system including an alternative fuel engine that propels a vehicle with an electric dc motor coupled to the vehicle's transmission.
