A method for operating a fuel injection system is provided. The method includes injecting fuel from a first direct fuel injection device arranged in a cylinder liner in a cylinder block into a combustion chamber and injecting fuel from a second direct fuel injection device arranged in a cylinder head into the combustion chamber, the first and second direct fuel injection devices arranged at an obtuse angle with regard to an intersection of central axes of the first and second direct fuel injection devices.

Methods and systems are provided for a hydrogen combustion engine. In one example, a method may include operating the hydrogen combustion engine at one of two combustion air ratios, wherein a combustion air ratio between the two is avoided via adjusting one or more operating parameters.

Methods and systems for a vehicle

Methods and systems are provided for a prechamber. In one example, the prechamber comprises an interior volume fluidly coupled to flow channels of an ignition plug and a bracket. The bracket is configured to move relative to the ignition plug and a cylinder head to misalign the flows channels and block the flow of air to the interior volume.

Methods and systems for a prechamber

An internal combustion engine of a motor vehicle is provided. The internal combustion engine includes a coolant, a liquid/gas heat exchanger, a coolant-temperature-dependent control element, an equalizing tank, fluidic connections between the components, and a coolant pump. At least one direct or at least one activation-dependent fluidic connection or at least one force-transmitting connection is set up between a medium in the equalizing tank and a medium of at least one other media path or media circuit of the motor vehicle.

Methods and systems are provided for a particulate filter comprising a pretreatment. In one example, a method may include applying a pretreatment to an unused particulate filter, wherein the particulate filter is subjected to incomplete oxidation conditions following application of the pretreatment.

Examples are provided for switching an engine fuel supply. One example system includes a direct-injection engine including a cylinder, an LPG tank for storing a LPG fuel, a CNG tank for storing a CNG fuel, a gas switching valve, a high-pressure pump connected between the LPG tank and the gas switching valve, a pressure-limiting valve connected between the CNG tank and the gas switching valve, a fuel distributor configured to be supplied with one or more of the LPG fuel and the CNG fuel via the gas switching valve, an LPG injection valve coupled to the cylinder, a CNG injection valve coupled to the cylinder, the LPG injection valve and the CNG injection valve configured to be supplied with fuel via the fuel distributor; and a controller configured to control the gas switching valve depending on an aggregate state of the fuel disposed in the fuel distributor.

Methods and systems are provided for a close-coupled aftertreatment device. In one arrangement, a system may include an engine comprising separate first and second overall exhaust lines, where a blow-off line branches off of the second overall exhaust line, and where the close-coupled aftertreatment device is arranged in the blow-off line and configured to receive exhaust gases during at least a cold-start of the engine.

Methods and systems for a blow-off line

Examples are directed to a fuel injection device positioned in a cylinder liner. In one example, a cylinder includes a combustion chamber which is jointly formed by a piston crown of a piston, by a cylinder barrel which laterally delimits the combustion chamber, and by a cylinder head. The cylinder includes an injection device positioned in the cylinder barrel for direct introduction of fuel into the combustion chamber, which injection device has at least one opening which, during a course of an injection process, is configured to be activated to introduce fuel into the combustion chamber, the injection device terminating flush, at a combustion chamber side, with the cylinder barrel.

Systems and methods are provided for an engine wherein one group of cylinders is active and a second group of cylinders is switchable, such that under low loads the second group of cylinders is deactivated, and under high loads the second group of cylinders is activated. Following deactivation of the second group of cylinders a throttling element in an intake line for the second group of cylinders is gradually closed. The closing of the throttling element may reduce pumping losses and thus increase engine efficiency.

Methods and systems are provided for introducing water into an intake manifold of an internal combustion engine. In one example, the system may include a water container, a water inlet for inputting water into the intake manifold, and a throttle valve that is arranged between an intake manifold inlet and the internal combustion engine, with the water container arranged at a higher point than the water inlet and the water inlet opening into the intake manifold downstream of the throttle valve. A switchable valve is arranged in fluidic connection with both the water container and the water inlet, with the result that it can enable or interrupt the introduction of water into the intake manifold and also create a Venturi effect at the water inlet, which draws water from the water container.

The present disclosure relates to methods for producing spark plugs and/or spark plug components, and a capsule which may be used to produce a spark plug or spark plug component. The capsule may include a housing of a material which is unstable when heated a threshold temperature, and the capsule may further be filled with one or more powders, whereupon heating of the capsule of the housing may break down and the powders may be sintered or fused into a resistive body. The presently disclosed method may simplify and/or reduce the cost of producing spark plugs using known methods of inserting powdered precursor materials.

Methods and systems are provided for injecting fuel into a combustion chamber of an engine. In one example, a system may include a hollow cone-shaped injector and a control unit to control the injector. The control unit may detect the position of an inlet valve and trigger the injection process, wherein the injector may be configured to spray fuel out of an inlet duct, through an annular gap, and into the combustion chamber of an engine in an injection process.

Method and system for fuel injection

A system for filtering and oxidizing particulate matter produced by a gasoline direct injection engine is disclosed. In one embodiment, engine cylinder air-fuel is adjusted to allow soot to oxidize at an upstream particulate filter while exhaust gases are efficiently processed in a downstream catalyst.
