Abstract: A vehicle, system, and method include a first tank configured to contain compressed gaseous fuel, such as hydrogen, and a second tank fluidly couplable to the first tank and an internal combustion engine, the second tank configured to store the gaseous fuel from the first tank in a communal cavity with a non-combustible liquid, such as water, without a bladder or physical separation barrier therebetween, and to selectively deliver the gaseous fuel via a first outlet, and the non-combustible liquid via a second outlet, to the internal combustion engine. A turbine may be disposed between the first and second tanks. One or more condensers may condense water from engine exhaust and/or an air conditioning system and pump the liquid water into the second tank. Pressure within the second tank may be controlled via fuel supplied by the first tank and/or liquid supplied via the condensers and pump.

Abstract: Methods and systems are provided for a cylinder head. In one example, a system comprises cylinder head having a bore arranged therein. The bore comprises a coupling element therein configured to selectively receive an ignition plug.

Abstract: An applied-ignition internal combustion engine having at least one cylinder head comprising at least one cylinder and having a rotatably mounted crankshaft is provided. In the internal combustion engine each cylinder has an inlet opening, which is adjoined by an intake line, and an outlet opening, which is adjoined by an exhaust-gas line, each opening being equipped with a valve, each cylinder comprises a combustion chamber which is jointly formed by a piston crown of a cylinder-specific piston, by a cylinder liner and by the cylinder head. Additionally, the crankshaft is articulably connected to the piston of each cylinder, such that, as the crankshaft rotates about an axis of rotation, the piston oscillates along a cylinder longitudinal axis, where the cylinder longitudinal axis is perpendicular to the axis of rotation of the crankshaft.
