    • A method of affecting a mixture formation and motion of a charge in a cylinder of an externally ignited internal-combustion engine during a suction cycle of a gas intake valve of the cylinder. The suction cycle has a first cycle portion and a second cycle portion; the second cycle portion constitutes an end portion (leading and/or trailing end portion) of the suction cycle. The gas intake valve has, during the first suction cycle, a first open position at full valve stroke in which the gas intake valve has a fully open cross-sectional flow passage area. The method includes the step of maintaining the gas intake valve in a second open position at a partial stroke of the gas intake valve during the second cycle portion. The partial stroke is less than one half of the full stroke, and in the second open position the gas intake valve has a partially open cross-sectional flow passage area. The method further includes the step of maintaining the gas intake valve in the first open position during the first cycle portion.
    • 一种在气缸的进气阀的吸入循环期间影响外部点燃的内燃机的气缸中的混合物形成和运动的方法。 抽吸循环具有第一循环部分和第二循环部分; 第二循环部分构成吸入循环的端部(前端部和后端部)。 在第一抽吸循环期间,进气门在全阀行程处具有第一打开位置,其中进气阀具有完全敞开的横截面流动通道区域。 该方法包括在第二循环部分期间将进气门维持在进气阀部分行程的第二打开位置的步骤。 部分行程小于全行程的一半,而在第二打开位置,进气阀具有部分开放的横截面流动通道面积。 该方法还包括在第一循环部分期间将进气阀保持在第一打开位置的步骤。

    • A four-stroke Otto engine. At least two intake valves of the engine have an open position and a closed position, and include a main intake valve and an additional intake valve. A camshaft moves the main intake valve into its open position and into its closed position, and a transmission element transmits a motion of the camshaft to the main intake valve. The transmission element includes a cutoff apparatus actuatable independently of the camshaft for cutting off a transmission of the actuation of the camshaft to the main intake valve for keeping the main intake valve in its closed position in a lower partial load and rpm range of the engine. An operating apparatus connected to the additional intake valve actuates the additional intake valve independently of the actuation of the main intake valve for moving the additional intake valve into its open position in a lower partial load and rpm range of the engine and into its closed position in an upper partial load and rpm range of the engine. The operating apparatus further adjusts at least one of a valve stroke of the additional intake valve, a valve opening time of the additional intake valve and a valve closing time of the additional intake valve as a function of engine load. An intake control device controls the cutoff apparatus and the operating apparatus.
