    • A method and a device for operating an internal combustion engine including at least one cylinder are described, the at least one cylinder including at least one intake valve and at least one exhaust valve and a diagnosis of at least one erroneous intake valve or at least one erroneous exhaust valve is made possible without using a position acknowledgment. A gas exchange of the at least one cylinder is diagnosed thereby. For detection of at least one intake valve or exhaust valve for the existence of an erroneous valve position, at least one intake valve or exhaust valve of the at least one cylinder different from at least one intake valve or exhaust valve to be detected is brought into a predefined position, which is selected in such a way that the gas exchange of the at least one cylinder in the case of an erroneous valve position of the at least one intake valve or exhaust valve to be detected differs significantly from the gas exchange of the at least one cylinder for the case of an error-free valve position of the at least one intake valve or exhaust valve to be detected, a value characteristic for the gas exchange of the at least one cylinder being ascertained, this value being expected at the moment for an error-free state of the set valve positions of the at least one intake valve and the at least one exhaust valve of the at least one cylinder, the actual value characteristic for the gas exchange of the at least one cylinder being ascertained and an error in the position of the at least one intake valve or exhaust valve to be detected is recognized as a function of the deviation in the actual value from the expected value.

    • A DMOS-transistor having enhanced dielectric strength includes a first well region. A highly doped source region is located in the first well region and is complementarily doped thereto. A highly doped bulk connection region is located in the first well region and has the same type of doping as the first well region. A gate electrode and a gate insulation layer for forming a transistor channel are included on a surface of the first well region. The DMOS-transistor further comprises an isolation structure, a highly doped drain doping region, and a second well complementarily doped to the first well region. The second well accommodates the first well region and the drain doping region. A highly doped region is formed at least adjacent to the second well and has the same type of doping as the second well for enhancing the dielectric strength of the highly doped source region.

    • A method for operating an internal combustion engine, a computer program product, a computer program, and a control and/or regulating device for an internal combustion engine make detection of an erroneously permanently closed intake valve for a cylinder of the internal combustion engine having more than one intake valve possible. Air and fuel are supplied to the cylinder of the internal combustion engine via a plurality of intake valves. The air and fuel are supplied to the cylinder via a shared duct, which opens into separate ducts for each intake valve of the cylinder. The separate ducts have the same volume. After an interruption of the fuel supply to the cylinder, the fuel supply is resumed. Starting at a first point in time of the resumption of the fuel supply, the fuel quantity supplied to one of the separate ducts is ascertained assuming a permanently closed associated intake valve. A second point in time since the resumption of the fuel supply, at which the separate duct would be completely filled with fuel for the first time if the associated intake valve were permanently closed, is ascertained from the ascertained fuel quantity. A check is performed of whether the cylinder has relatively more combustion misses between the first point in time and the second point in time than after the second point in time. In this instance, it is concluded that an intake valve of the cylinder is erroneously closed.
    • 用于操作内燃机的方法,计算机程序产品,计算机程序和用于内燃机的控制和/或调节装置使得检测到具有更多的内燃机的气缸的错误永久关闭的进气阀 比一个进气阀可能。 空气和燃料经由多个进气阀供给到内燃机的气缸。 空气和燃料通过共享管道供应到气缸,该共用管道对于气缸的每个进气阀开启到单独的管道。 独立的管道具有相同的体积。 燃料供应中断之后,燃料供应被恢复。 从燃料供应恢复的第一时间点开始,假设供给到一个独立管道的燃料量假设为永久关闭的相关进气阀。 从燃料供应恢复以来的第二个时间点,如果相关联的进气门永久关闭,则单独的管道将首次完全充满燃料,这是从确定的燃料量确定的。 检查气缸在第一时间点和第二时间点之间是否具有比第二时间点之后相对更多的燃烧失误。 在这种情况下,可以认为气缸的进气门被错误地关闭。
