本发明涉及一种用于对机动车辆的驱动系统进行单独润滑的润滑方法。
【背景技术】
驱动系统的润滑组合物必须满足有时矛盾的多种目标。这些目标源于发动机润滑组合物的五个主要功能,即润滑、冷却、密封、防腐蚀和压力传递。
相互滑动的组件/部分的润滑起着关键的决定作用,特别是用于减少摩擦和磨损,由此特别允许用于节省发动机燃料。
用于驱动系统的润滑组合物的另一个基本要求涉及与环境有关的方面。事实上,减少汽车燃料消耗,特别是在以减少二氧化碳排放量为意图的情况下,已经变得至关重要。同样重要的是减少有害气体的排放,例如通过以这样的方式配制润滑组合物,使得催化剂在其整个寿命期间保持完全的功能。同样重要的是,限制或避免使用有毒添加剂,以减少或限制它们的消除,例如通过再加工、后处理或燃烧的方式。
因此,用于驱动系统的润滑组合物的性质对污染物排放和汽车燃料消耗具有影响。根据公认的术语,通常将能够实现节能的用于驱动系统的润滑组合物称为“燃料经济性(Fuel economy)”(FE)。为了满足这些新的需求,开发了这种“燃料经济性”油。
大多数当前的机动车辆配备有一个驱动系统,在该驱动系统中使用单一润滑组合物来润滑所述驱动系统的各种不同的组成部件。
然而,在同一给定的驱动系统中要润滑的各种组件的特性特征和约束是不同的。由于目前使用单一润滑组合物的做法,单一润滑组合物并不特别适用于待润滑的不同部件,而是在待润滑的部件的所有的特性特征和约束之间呈现折衷。因此,在燃料经济性上获得的增益并不是最优的。
因此,有兴趣开发能够提供用于对各种不同的组成部件进行单独润滑的驱动系统,并开发用于对驱动系统的不同的组成部件进行单独润滑的润滑方法。
【发明内容】
本发明的一个目的是使得能够在用于机动车辆的驱动系统的润滑中实现燃料经济性上的显着增益,特别是燃料经济性上的至少3%的增益。
本发明的另一个目的是使所述用于机动车辆的所述驱动系统中的特定于且适于待润滑的各种不同的组成部件的润滑组合物的操作实施成为可能。
通过阅读下面对本发明的描述,其它目的将变得显而易见。
这些目的通过本发明实现,其提供了一种用于对机动车辆的驱动系统进行单独润滑的润滑方法,所述系统包括内燃发动机,所述内燃发动机包括耦合在一起的发动机顶部部分(或顶端)和发动机底部部分(或底端),所述方法包括:
-用具有由式(X)W-(Y)定义的SAE J300等级的润滑组合物(CL1)来润滑发动机底部部分,其中X代表0或5且Y代表4,8,12,16或20;以及
-用不同于润滑组合物(CL1)的润滑组合物(CL2)来润滑发动机顶部部分。
在本发明的上下文中,术语“单独润滑”被理解为指示如下的事实:根据待润滑的组成部件存在单独的润滑组合物,典型地为至少两种单独的润滑组合物,一种用于润滑发动机顶部部分(顶端)的元件,另一种用于润滑发动机底部部分(底端)的元件。以有利的方式,如下所示,驱动系统包括至少两个单独的润滑系统,其中一个供应发动机顶部部分,第二个供应发动机底部部分。
在本发明的上下文中,术语“分离的润滑组合物”或“不同的润滑组合物”被理解为是指通过它们的组成元素,特别是通过它们的组成元素的性质,和/或通过组合物的各种不同的组成元素的比例来彼此区分的润滑组合物。
在一种有利的方式中,这种方法使得有可能在发动机底部部分和发动机顶部部分处对润滑剂进行优化。
在本发明的上下文中,术语“发动机顶部部分”(顶端)被理解为指由组装在发动机底部部分上的汽缸盖或多个汽缸盖构成的发动机的部分。汽缸盖是用于通过进气管和进气阀来在燃烧室中分配进气并且用于通过排气管和排气阀来排出燃烧气体的座。
在本发明的上下文中,术语“发动机底部部分”(底端)被理解为是指包括在包含气缸的“发动机机体”和包含发动机润滑剂的壳体内的可移动联接器(连杆,活塞和曲轴)的发动机的部分。
“发动机底部部分”和“发动机顶部部分或多个顶部部分”之间的边界表现在气缸盖的一个或多个密封件中。
在下面的部分中,术语“顶部”、“上部”及其等同物被用来表示当车辆处于使用位置时垂直朝向车辆顶部的方向,在使用位置中车辆例如是静止在地面上的。术语“底部”、“下部”及其等同物用于表示相反的方向。
作为变体,本发明也可应用于具有与上述驱动系统的示例不同的空间配置的发动机,特别是所谓的“平置式(flat)”发动机。可以理解的是,在这些特定的发动机的情况下,发动机顶部部分不一定被放置在发动机底部部分的上方。因此,在这些特定发动机的情况下,上文定义的术语“发动机顶部部分”用于指特别是配备有一个或多个控制轴和分配系统的气缸盖,术语“发动机底部部分”用于指曲轴箱以及发动机机体,特别是配备有活塞、连杆、曲轴、气缸和燃烧室。
在一个特定实施例中,本发明涉及一种用于对机动车辆的驱动系统进行单独润滑的润滑方法,所述系统包括压缩机,优选涡轮压缩机,内燃发动机,所述内燃发动机包括耦合在一起的发动机顶部部分和发动机底部部分,所述方法包括:
-用具有由式(X)W-(Y)定义的SAE J300等级的润滑组合物(CL1)来润滑发动机底部部分,其中X代表0或5且Y代表4,8,12,16或20;
-用与润滑组合物(CL1)不同的润滑组合物(CL2)来润滑发动机顶部部分;以及

优选地,在本发明的上下文中,组合物(CL1)在150℃下具有至多等于2.9mPa.s,优选地包括在1.4mPa.s和2.75mPa.s之间、优选地包括在1.7mPa.s和2.75mPa.s之间的HTHS(高温高剪切粘度测量)。
根据标准化方法CEC-L-36-A-90、ASTM D4683和ASTM4741,在高剪切(106sec-1)和高温下执行HTHS测量。
优选地,根据本发明的组合物(CL1),(CL2)和(CL3)包含至少一种基础油和添加剂,应理解组合物(CL1),(CL2)和(CL3)彼此不同也就是说它们包含不同的基础油和/或不同的添加剂和/或不同比例的基础油和/或添加剂。
根据本发明的润滑组合物中使用的基础油可以是矿物油或合成油,其属于根据在美国石油学会(API)分类中定义的类别的I至V组((或根据Association Technique de L'Industrie Européenne des Lubrifiants/欧洲润滑剂工业技术协会(ATIEL)分类的其等同物)(表A)或其混合物。

也可以使用合成油和矿物油的混合物。
根据本发明的润滑组合物的基础油也可以从诸如某些羧酸酯和醇酯之类的合成油中以及从聚α-烯烃中选择。作为基础油的聚α-烯烃例如是从含有4至32个碳原子的单体而获得的,例如来自辛烯或癸烯,并且根据根据美国测试和材料协会标准ASTM D445,其在100℃(Kv100)的运动粘度包括在1.5mm2.s-1和15mm2.s-1之间。根据ASTM D5296标准,它们的平均分子量一般包括在250和3000之间。
相对于组合物的总重量,根据本发明的润滑组合物可以包括至少50%重量的基础油。以更有利的方式,根据本发明的润滑组合物相对于组合物的总重量包含至少60%重量,或甚至至少70%重量的基础油。以特别更有利的方式,相对于组合物的总重量,根据本发明的润滑组合物包含75-99.9%重量的基础油。

以有利的方式,相对于润滑组合物的总重量,根据本发明的润滑组合物可以包含0.01-6%重量,优选0.05-4%重量,更优选0.1-2%重量的抗磨添加剂和极压添加剂。在特别优选的方式中,润滑组合物(CL1)不包含任何抗磨添加剂。有利地,润滑组合物(CL1)不包括诸如ZnDTP(二硫代磷酸锌),MoDTP(二硫代磷酸钼)或硫化烯烃之类的任何抗磨添加剂。

以有利的方式,根据本发明的润滑组合物可以包括至少一种抗氧化剂添加剂。
抗氧化剂添加剂通常提供延迟使用中的润滑组合物降解的手段。这种降解特别是可能以沉积物的形成,由污泥的存在或由润滑组合物粘度的增加而反映的。
抗氧化剂添加剂特别用作自由基抑制剂或氢过氧化物的驱除剂。在通常使用的抗氧化添加剂的类型中,可以涉及酚类抗氧化添加剂,胺抗氧化添加剂,磷硫酚抗氧化添加剂。这些抗氧化添加剂中的某些,诸如磷硫抗氧化添加剂可能容易产生灰烬。酚类抗氧化添加剂可以不含灰分,或者确实是以中性或碱性金属盐的形式。抗氧化添加剂可选自位阻酚,包括硫醚桥的位阻酚和阻酚酯,二苯胺,被至少一个C1-C12烷基取代的二苯胺,N,N'-二烷基-芳基二胺及其混合物。

硫化烷基酚或其碱金属盐和碱土金属盐也可用作抗氧化添加剂。
另一类抗氧化添加剂是铜化合物,例如硫代或二硫代磷酸酯的铜、铜盐和羧酸盐、二硫代氨基甲酸酯、磺酸盐、酚盐、乙酰丙酮铜。还可以使用铜(I)和铜(II)盐、酸盐或琥珀酸酐盐。

洗涤剂添加剂通常能够通过溶解氧化和燃烧的二次产物来减少在金属部件表面上的沉积物的形成。
在根据本发明的润滑组合物中使用的洗涤添加剂通常是本领域技术人员所熟知的。洗涤添加剂可以是包括亲油性长烃链和亲水性头的阴离子化合物。相关的阳离子可以是碱金属或碱土金属的金属阳离子。
洗涤添加剂优选地选自羧酸的碱金属盐或碱土金属盐、磺酸盐、水杨酸盐、环烷酸盐,以及酚盐的盐。碱金属和碱土金属优选地为钙、镁、钠或钡。
这些金属盐通常含有以化学计量的量或实际上过量的金属,因此在量上超过化学计量的量。于是这些是高碱性洗涤添加剂;向洗涤添加剂提供高碱性特征的过量的金属于是通常为以在油中不溶的金属盐的形式,例如碳酸盐,氢氧化物,草酸盐,乙酸盐,谷氨酸盐,优选地为碳酸盐。
以有利的方式,相对于润滑组合物的总重量,根据本发明的润滑组合物可以包括0.5至8%重量或2至4%重量的洗涤添加剂。
以同样有利的方式,根据本发明的润滑组合物还可以包括至少一种倾点抑制添加剂(倾点抑制剂PPD)。

本专利申请将通过使用下面给出的非限制性示例来说明。
根据本发明的润滑方法已经在图2表示的驱动系统中在操作上实施,所使用的发动机是来自汽车制造商PSA Peugeot Citroen的DW10发动机。用相互不同的组合物(CL1)和(CL2)执行两次测试。
在这些测试中:

-计算在以单独的润滑配置的发动机中的候选油CL1与以非单独的润滑配置的发动机中的参考油之间可比较的操作点上的消耗上的相对增益。
通过这种方法,可以通过使用具有专门为发动机底部部分配制的候选油CL1的单独的润滑发动机系统来在每个操作点上比较在燃料消耗上的增益。
针对测试1和2的在燃料消耗上的增益的结果在下表II中给出:
