摘要： 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.

摘要： Methods and systems are provided for optimizing the operation of a multi-cylinder auto-ignition internal combustion engine. In one example, cylinders of the auto-ignition internal combustion engine may form two groups of cylinders, where one group of cylinders has a larger compression ratio, smaller width, and smaller volume than the other group of cylinders, and where at least one cylinder of the other group is configured as a switchable cylinder that is deactivated in a load-dependent manner. By configuring the cylinders in multiple groups based on compression ratios, and operating the cylinders in a load-dependent manner, fuel consumption may be optimized.

摘要： The application relates to spark initiation under varied aircharge density and composition. An engine is disclosed comprising at least two cylinders with spark plugs therein; an integrated exhaust manifold, the integrated exhaust manifold having a wall portion and an adjustable shutoff element within the wall portion wherein the wall portion divides exhaust pipes of the at least two cylinders and the adjustable shutoff element allows exhaust gas from a first cylinder into an exhaust pipe of an adjacent cylinder. Hot exhaust gas may be taken into an adjacent cylinder serving as ignition gas and allowing the engine of the present disclosure to undergo spark ignition at low loads, or autoignition at high loads.
