  • Patent number: 10590898
    Abstract: 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.

  • Patent number: 10443515
    Abstract: 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.

  • Patent number: 10288012
    Abstract: 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.

  • Patent number: 10090649
    Abstract: 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.
