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.

Direct-injection, applied-ignition internal combustion engine with injection device arranged in the cylinder liner, and method for operating an internal combustion engine of said type

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

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.

Internal combustion engine with injection device arranged in the cylinder barrel, and method for operating an internal combustion engine of said type

A method for operating an engine system is provided. The method includes during a first operating condition, flowing oil from an oil sump to a heat exchanger attached to a reductant tank and transferring heat from oil flowing through the heat exchanger to reductant stored in the reductant tank. The method further includes during a second operating condition, flowing oil from the oil sump to the heat exchanger and transferring heat from the reductant stored in the reductant tank to oil flowing through the heat exchanger.

Reductant tank as a heat storage device

An exhaust system for an internal combustion engine is provided. The exhaust system includes an exhaust manifold receiving exhaust gas from a cylinder, an emission control device positioned downstream of the exhaust manifold, an electric heating device positioned in an exhaust line upstream of the emission control device and downstream of the exhaust manifold, the electric heating device including a frame at least partially surrounding a heating element, and an adjustment device configured to, during operation of the internal combustion engine, adjust the drag generated by the electric heating device in an exhaust gas flow through the exhaust line.

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.

Method for controlling fuel of a spark ignited engine while regenerating a particulate filter

The disclosure relates to a method for operating an internal combustion engine having a plurality of cylinders, the method comprising, during one working cycle, distributing fuel for each cylinder of the plurality of cylinders among a plurality of injection processes according to settable split factors which respectively define a setpoint fuel mass and/or injection duration and time setting of each respective injection process for the plurality of individual injection processes, wherein random variation is carried out for at least one injection process.

Method and device for operating an internal combustion engine

A lubrication system in an internal combustion engine is provided. The lubrication system includes a crankshaft bearing supporting a crankshaft, a supply line including an outlet flowing oil to the crankshaft bearing and an inlet receiving oil from an oil gallery, and thermal insulation at least partially surrounding at least a portion of an inner wall of the supply line and/or the oil gallery.

Internal combustion engine with a lubrication system and method for producing an internal combustion engine

A system is provided for an internal combustion engine including at least two cylinders, wherein the at least two cylinders form at least two groups, wherein each group has at least one cylinder, the at least one cylinder of at least one group being formed as a cylinder which can be activated in a load-dependent manner and which is deactivated if a predefined load is undershot. The at least two groups are characterized by different cylinder volumes, the at least one cylinder of a first group having a lesser cylinder volume and the at least one cylinder of a second group having a greater cylinder volume and configured as an activatable cylinder.
