Description

用于控制内燃机的方法和装置
技术领域
本发明涉及一种用于控制内燃机的方法和装置，该内燃机具有一个进气装置，该装置具有用于内燃机气缸入口的进气管、用于通过关闭或打开至少一个从进气管通向一个空心体的开孔来调节进气管有效管长的执行机构以及至少一个用于控制该执行机构的伺服驱动机构。
背景技术
由DE 197 17 347 C1已知这样一种用于内燃机的进气装置。设计为开关阀的执行机构根据内燃机曲轴的转速N和/或空气质量流和/或进气管压力通过伺服驱动机构偏转到一个打开位置或者偏转到一个关闭位置。由此根据内燃机的转速得到两个不同的进气管有效长度。在这种情况下，进气管的有效长度分别对应于这样的长度，即，进气管中的气柱在该长度上振荡。当开关阀偏转到其关闭位置时，这个长度为进气管的整个长度，而当开关阀在其打开位置时，所述有效长度只是进气管从气缸入口通向开关阀的一段。
发明内容
因此本发明要解决的技术问题是，提供一种方法和一个装置，它们能够保证一个内燃机具有非常好的扭矩变化过程。
这个技术问题通过独立权利要求的特征得以解决。本发明的有利方案在从属权利要求中给出。本发明的特征在于，在第一转速范围内，其上限是一个第一阈值，执行机构被控制在一个关闭位置中；当转速高于第一阈值且低于第二阈值时，该执行机构被控制在一个泄漏位置中，而当转速高于第二阈值时，执行机构被控制在一个打开位置中。由此在第一转速范围保证较长的有效进气管长度，而在高于第二阈值的转速范围保证较短的有效进气管长度。由此在这些转速范围里能够分别实现对内燃机气缸的非常好地增压。此外在转速高于第一阈值而低于第二阈值的转速范围里通过执行机构的泄漏位置明显地改善气缸增压。
附图说明
下面借助于示意性的附图描述本发明的实施例。附图示出：
图1  一个具有一个吸气机构1的内燃机，
图2  按照图1的吸气装置沿着II-II’线的截面图，
图3  设置在吸气装置1中的一个开关阀，
图4  一个用于控制内燃机的流程图。
具体实施方式
结构和功能相同的元件在附图中以相同的附图标记表示。
一个内燃机的吸气装置1(图1)具有一个吸气管接头2，在其中最好设置一个节流阀3。该吸气管接头2与一个第一收集器4连接，从那里进气管5、6、7、8再通向发动机缸体的入口11、12、13、14。一个第二收集器9设计成在第一收集器4的下游和入口11至14的上游。在第二收集器9的范围里设计为开关阀20、21、22的执行机构用于关闭或打开至少一个从吸气通道通向一个空心体的开孔。在这种情况下，在这种方案中所述空心体分别是通向相邻进气管5至8的容积。但是在另一可选择的方案中也可以是一个附加的容积。但是该空心体也可以直接是第一收集器4，或间接地与第一收集器4、例如通过一个短的管接头连接。
此外设置一个伺服驱动机构18，它这样构成，即，使它适合于将开关阀控制在一个打开位置、一个关闭位置和至少一个泄漏位置中。该伺服驱动机构最好设计为电机。此外设置一个用于控制内燃机的装置19，它根据内燃机运行参数、例如内燃机曲轴的转速N产生用于伺服驱动机构18的控制信号。
图3示出按照图2的开关阀的一种可能的方案。该开关阀20具有一个轴23，它在一个自由端上直角地弯曲。该轴23形状配合连接地与一个叶轮体30连接。一种密封材料环绕叶轮体30喷铸并这样设计，使密封材料在开关阀的边缘侧面上构成一个密封唇37，它在关闭位置中与开孔的顶靠环带相接触并由此密封地关闭开孔。此外密封材料构成一个第一和一个第二密封盖39，40，它们与轴23同心地设置在开关阀20的相互对置的轴向端部上。
在一个步骤S1中开始一个控制内燃机的程序。在一个步骤S2中检测转速N是否高于一个第三阈值N0。如果不是这种情况，则在一个第三步骤S3中使开关阀20至22的位置S控制在一个打开位置OP中。在这个打开位置OP中开关阀20至22分别使通向相邻进气管5至8的开孔打开，由此使有效的进气管长度缩短到在那些开孔至发动机缸体上入口11至14之间的长度，在所述开孔里面设置所述开关阀20至22。所述第三阈值N0最好选择在900至1500转/分钟范围里面，例如1000转/分钟。从发动机试车台上的试验得出，对于这样的低转速，通过较短的有效进气管长度可以改善气缸的增压。
但是如果满足步骤S2的条件时，则在一个步骤S4中检查转速N是否高于第一阈值。如果是这种情况，则在一个步骤S5中使开关阀20至22的位置S控制在一个关闭状态CL中。在这个关闭状态CL中进气管20至22不与空心体连接，在这个实施例中空心体分别相应于各相邻的进气管。在其中设置开关阀20至22的开孔由此被关闭。由此得到一个有效的进气管长度，它相应于进气管从第一收集器4到入口11至14的整个长度。第一阈值最好选择在2800至4000转/分钟的范围中，例如3400转/分钟。由此可以在第三阈值N0与第一阈值N1之间的范围中保证一种非常好的气缸增压。
但是如果在步骤S4中转速N高于第一阈值N1，则在一个步骤S6中检查转速是否高于一个第二阈值N2。第二阈值N2最好位于4000至4800转/分钟，例如4200转/分钟。如果在步骤S6中转速低于第二阈值N2，则在一个步骤S7中根据转速N求得一个泄漏位置IM。在一个特别简单的方案中固定地预先给定该泄漏位置。但是如果泄漏位置是可变化的并根据转速求出，则可以实现进一步改善扭矩变化过程。如果这样计算泄漏位置IM，即，使泄漏随着转速N的提高而增加，则可以得到特别好的扭矩变化过程。在泄漏位置通过开关阀20至22只这样微小地打开所述开孔，使气流在进气管的这个部位不完全中断。在泄漏位置IM中通过开关阀20至22最多只这样大地敞开开孔，即，使所述开孔的敞开最多只相应于由各开关阀所关闭的开孔面积的15％的泄漏。
在一个步骤S8中控制开关阀在泄漏状态下的位置S。由此在第一阈值N1与第二阈值N2之间的转速范围里令人吃惊地明显地提高内燃机气缸的增压并由此提高转矩。所述开关阀最好设计得非常好地进行密封，如同借助于图3所示开关阀所描述的那样并由此在第三阈值N0与第一阈值N1之间的转速范围里非常紧密地以低于约1％开关面积的泄漏量关闭所述开孔，这一点在这个转速范围内是非常有利的。与此相比，在第一转速阈值与第二转速阈值之间的转速范围里泄漏位置IM更加有利地作用于扭矩变化过程。
但是如果满足步骤S6的条件，即，转速高于第二阈值N2，则在一个步骤S2中将开关阀20至22的位置S在步骤S3中控制在打开位置OP中，由此在转速高于第二阈值N2时得到一个非常好的扭矩变化过程。
执行机构在泄漏位置的控制附加有利地取决于内燃机的负载参数。因此泄漏位置例如只控制在接近满负荷的范围里，即例如当进气管压力在那个转速下相应于环境压力的时候。
