迫于同时开发重负荷柴油机油PC-11和乘用车汽油机油GF-6两个新发动机油规格的压力,润滑油和添加剂生产商希望这两个规格发布的期限可以再放宽一些。、2014年6月12日,PC-11规格开发小组描述了该规格所需的发动机程序试验的开发状态API新规格开发组之前曾表示目前API CJ-4发动机油的大部分试验和指标适用于新的PC-11规格,最终通过ASTM重负荷发动机油分类小组投票表决确定PC-11规格标准将从API CJ-4中保留6个发动机试验:通用汽车公司滚子从动件磨损试验、康明斯ISB气门磨损测试验、康明斯ISM试验、CATC13试验、Calerpillar 1N试验和Maek T-1l试验,这些试验将延用API CJ-4规格的指标。 相似文献

模拟试验和台架试验是内燃机油质量评定必不可少的环节,由于台架试验花费大,时间长,不利于新配方和新添加剂的研究,因此发展了一些快速及省时的模拟试验,它们模拟发动机中某部分的工作条件,与台架试验有一定的相关性,但也有局限性,如何看待这些问题,本文通过分析讨论提出了建议。 相似文献

Global economic and pollution concerns are having a major impact on how modern engine oils are being formulated. Modern engine oil specifications mandate reduced levels of phosphorus and sulfur to protect the efficacy of pollution control devices. In addition, modern engine oil must also be more fuel efficient than earlier generations to reduce greenhouse gas emissions and the impact of high priced gasoline and diesel fuel to the consumer. At the same time, oxidation, wear, and corrosion performance of the oil must not be compromised. Multifunctional additives are useful formulation tools that help formulators meet these tough new challenges. One such additive is the organo-borate ester/amide. Originally conceived as an organic friction modifier, this patented technology is really a multifunctional additive that addresses the global economic and pollution concerns. With the addition of boron, this unique commercial organic friction modifier also imparts antioxidancy, antiwear and anticorrosion properties to engine oil. In addition, the organo-borate ester/amide is compatible with pollution control devices because it does not contain sulfur or phosphorus. Work is on going to uncover additional beneficial properties of this chemistry. 相似文献

降低发动机油的磷含量,提高燃料经济性,延长使用寿命,已是润滑油升级换代大势所趋。为了降低磷的含量,必须减少二烷基二硫代磷酸锌(ZnDDP)的使用,而二烷基二硫代氨基甲酸锌(ZnDDC)是ZnDDP最理想的替代物。为了提高油品的燃料经济性,需要加入有机钼摩擦改进剂,其中,不含硫磷的钼酸酯添加剂,因其良好的减摩保持性,其应用更为突出。为了满足更苛刻的油品高温性能要求,还必须加入烷基化二苯胺类抗氧剂(ADPA)。因此有必要对非活性钼、ZnDDC和ADPA之间相互作用进行考察。研究表明,在非活性有机钼、ZnDDC、ADPA的三元添加剂体系中,存在着三种相互配合的协同作用:ZnDDC与非活性有机钼的抗磨协同。非活性有机钼与ADPA的抗氧化协同,以及ZnDDC与ADPA的抗氧化协同。利用非活性有机钼、ZnDDC、ADPA的三元非磷协同复合体系(OD0401),可以大幅度提高油品的抗氧化性能、减摩性能和抗磨性能,这对发展低磷含量的GF-4和GF-5发动机润滑油具有十分积极的意义。利用该协同复合添加剂OD0401,还可以有效地提高低档发动机油的抗氧化和抗磨性能。 相似文献

The Friction-Reducing, Antiwear and Antioxidation Properties of an Organo-Molybdenum Lube Additive without Sulfur and Phosphorus 总被引:4,自引:2,他引:2
The engine oil specifications of ILSAC GF - 4 ( implemented 2004 ) and GF - 5 ( expected 2010 ) have in common three important OEM needs: (1) improved fuel economy and its retention, (2) emissions system compatibility (related to phosphorus and sulfur content), and (3) improved oil robustness for extended oil life capability (e. g., reduced high temperature deposits and engine sludge, improved oxidative stability, and better valve train wear protec- tion). For emission systems compatibility, there is a trend towards lower phosphorus and sulfur content in engine oils while maintaining high anti - oxidation and anti - wear performances. In this paper, the friction - reducing, antiwear and antioxidant properties of a sulfurfree and phosphorusfree molybdate ester compound as lubricant additive are discussed. The investigation showed that the molybdate ester enables good frictionreducing ability of the lubricant, and maintains low friction coefficients even after period of severe oil oxidation, which indicates the potential for excellent fuel economy retention in passenger car vehicles. For other organomolybdenum additives, the investigation showed their frictionreducing ability decreased greatly after oxidation of the oil, although the performance appeared to be very good with the fresh oil before aging. In addition, the molybdate ester demonstrated a synergistic effect in anti - wear protection with zinc dialkyl dithiophosphate (ZDDP), a well- known commonly used additive in engine oils; this suggests that excellent wear protection is possible for an engine oil with reduced sulfur and phosphorus content. Moreover, the molybdate ester is also a strong synergist with arylamine antioxidants, which can retard its depletion in oxidized oil, extend its oxidative induction time, and reduce its high temperature deposit - forming tendency. Thus, this type of sulfur - free and phosphorus - free organo- molybdenum lubricant additive truly provides multifunctional performances, reducing friction, wear, and oxidation of an engine oil when combined with other suitable additives. Due to its phosphorus - free, sulfur- free and multifunctional properties, the molybdate ester compound can be extremely useful in formulat- ing modem engine oils with low phosphorus and sulfur content. 相似文献
