    • The invention relates to a method for at least temporarily increasing an exhaust gas temperature of a spark-ignition, direction injection internal combustion engine (10) involving at least one measure, which is executed by the engine, whereby this at least one measure consists of a spark retarding and of a multiple injection (ME). During the multiple injection (ME), at least two fuel injections into the cylinder (12) are carried out within an induction cycle and compression cycle of a cylinder (12) of the internal combustion engine (10), and the latest of these injections ensues during a compression cycle of the cylinder (12). The invention also relates to the utilization of the method. According to the invention, a control end of an injection angle (nullEE) of the latest injection is at least temporarily set to between 80 and 10null before an upper ignition dead center (ZOT) when operating with multiple injection and/or an ignition angle (nullZ) is at least temporarily set to between 10 and 45null after the upper ignition dead center (ZOT) also when operating with multiple injection. A combination of both measures enables a dramatic acceleration of the warming up of a catalytic converter (16) that is connected downstream from the internal combustion engine (10).

    • The present invention provides an ignition method for an internal combustion engine, an injection being alternatively carried out in at least one first operating mode (H1, H2) or in a second operating mode (S), and the ignition coil being charged as a function of the current operating mode.

The present invention also provides a corresponding ignition device for an internal combustion engine.

    • The invention relates to two methods for controlling a fuel metering of a direct-injection internal combustion engine (10) in a multiple injection operating mode according to which at least two fuel injections into a cylinder (12) are carried out during a compression cycle of the cylinder (12) of the internal combustion engine (10) by means of at least one injection valve (22). The invention provides that a pressure (rail pressure, pR), under which the fuel is stored in front of the injection valve (22), is preset in such a manner and/or injected fuel portions of the individual injections of a combustion cycle and/or a total fuel quantity, which is injected during a multiple injection, are varied in such a manner as to prevent a forthcoming valve opening time (nullt) of the injection valve (22) from falling below a preset valve opening time (nulltK) during at least one injection of a combustion cycle. The inventive measures ensure, with simple means, a precise fuel metering in the multiple injection operating mode and thus enable an application of the multiple injection operating mode over wide operating ranges, particularly also in the low load operating mode and idle operating mode.
    • 本发明涉及用于以多次喷射操作模式控制直喷式内燃机(10)的燃料计量的两种方法,根据该方法,在压缩循环期间执行至少两个喷射到气缸(12)中的燃料喷射 内燃机(10)的气缸(12)通过至少一个喷射阀(22)。 本发明提供在燃料循环的各个喷射的燃料部分和/或喷射燃料部分中预先设置燃料储存在喷射阀(22)前方的压力(轨道压力pR) /或在多次喷射期间喷射的总燃料量以防止喷射阀(22)的即将到来的阀打开时间(Deltat)低于预设阀打开时间(DeltatK)的方式变化, 在燃烧循环的至少一次喷射期间。 本发明的措施通过简单的手段确保在多次喷射操作模式下的精确燃料计量,并且因此能够在宽的工作范围内,特别是在低负载运行模式和空转操作模式下,可应用多次喷射操作模式。

    • In a direct start of an internal combustion engine, sufficient energy may need to be released in a first combustion to set the internal combustion engine into motion, if possible without the assistance of an additional assembly, such as an electromotive starter. For this reason, the carburetion of an air-fuel mixture, made up of the air mass present in a combustion chamber and the fuel mass injected therein, is of great importance. In order to improve the mixture formation during a start, e.g., during a warm start of an internal combustion engine, the fuel mass required for a mixture formation is introduced into the combustion chamber, in full or in part, already prior to a start phase by at least one injection, and the mixture formation may be improved in this manner by vaporization of the introduced fuel mass.
    • 在内燃机的直接启动中,如果可能,在第一次燃烧中可能需要释放足够的能量以将内燃机设置成运动,如果可能的话,不需要诸如电动起动器的附加组件的辅助。 因此,由燃烧室中存在的空气质量和喷射的燃料组成的空气 - 燃料混合物的化油是非常重要的。 为了改善起动期间的混合物形成,例如在内燃机的暖启动期间,混合物形成所需的燃料质量已经在起始阶段之前已全部或部分地被引入燃烧室 通过至少一次注射,并且可以通过引入的燃料质量的汽化以这种方式改善混合物形成。
