本文在NMMA TC-W3油和JASO FC油评定技术及其装备的基础上,提出了水、陆通用高性能环保型二冲程油的评定技术方案,即通用油评定程序包括:通用油的清净性评定试验、润滑性评定试验以及排烟特性评定试验。并制定了相应的试验方法。通过对风水冷二冲程润滑油清净性评定技术及其装备的研究,提出了通用油清净性评定方法,并建立了相应的单缸、液冷比亚乔180发动机试验台架——通用油清净性评定台架。采用水冷TC-W3油润滑性评定方法,作为通用油润滑性的评定方法;并选用日本本田 (HONDA)生产的HONDA AF27风冷发动机,建立了相应的润滑性试验台架——通用油润滑性评定台架。采用风冷JASO FC油的排烟试验方法作为通用油的排烟评定方法;同时,为了减少投资,本文采用风冷二冲程油排烟的试验台架作为通用油排烟试验台架。选用不同的TC-W3 油分别进行舷外机的系泊试验和OMC J70舷外机试验,试验结果与通用油清净性评定台架上的试验结果相比较,结果表明,通用油清净性评定台架试验结果正确,区分效果明显。选用不同的风冷标准参比油,在通用油清净性评定台架上进行试验,结果表明,风冷二冲程润滑油的清净性明显优于水冷二冲程润滑油,并制定了通用油的清净性通过指标。对通用油的润滑性评定试验台架以及通用油排烟试验台架进行验证试验,试验结果表明,台架试验结果正确。本文使用Visual C++程序语言独立开发了通用二冲程油润滑性评定试验数据自动采集、处理软件系统,提高了试验数据的测量精度,减轻了试验人员的工作量。本文选用美国 TC-W3复合剂(S833)配制出符合TC-W3标准的标准TC-W3润滑油(标准油),以该标准油为基础油强化配方,在确保其润滑性等TC-W3指标前提下,加强基础油及功能添加剂,降低其排烟,减少沉积物的生成,配制成通用油油样6个。通过分析,本文筛选出符合粘度级别SAE20的通用油油样1号样和符合粘度级别SAE30的通用油油样5号样作为通用油的备选油样。对通用油1号样和5号样进行通用油评定试验,由试验结果可知:通用油5号样通过了通用油清净性试验和润滑性试验,但没有通过排烟试验。而通用油1号样则通过了通用油评定的所有程序,说明本文所配制的通用油1号样是既符合风冷JASO FC标准又符合水冷TC-W3标准的高性能环保型的通用油。
Based on the evaluating techniques and equipment of NMMA TC-W3 oils andJASO FC oils, the proposal of evaluating technique for amphibian excellentenvironmental protection type two-stroke oil was put forward in the dissertation,which included detergency test procedure, lubricity test procedure, and smoke testprocedure for evaluating amphibious two-stroke gasoline engine oils.By research on the evaluating technique for excellent air-cooled, andexcellent water-cooled two-stroke oils, the detergency test procedure forevaluating amphibious two-stroke gasoline engine oils was established. Andcorrespond to the test procedure, the test-bed, adopting single cylinder, liquid-cooled,Piaggio 180 engine, was established, which was applied to evaluate detergency ofamphibious two-stroke gasoline engine oils.The lubricity test procedure for evaluating excellent water-cooledtwo-stroke oil (TC–W3 oils) was introduced to evaluate the lubricity ofamphibious two-stroke gasoline engine oils. And the test-bed adopting air-cooledHONDA AF 27 type engine was founded——the test-bed for evaluating detergencyof amphibious two-stroke gasoline engine oils.The smoke test procedure for evaluating excellent air-cooled two-stroke gasolineengine oils was used for evaluating smoke of amphibious two-stroke gasoline engineoils. A t the same time the test-bed for evaluating excellent air-cooled two-stroke oils(JASO FC) was utilized to evaluate the smoke of amphibious two-stroke gasolineengine oils.Selected different excellent water-cooled two-stroke oils (NMMA TC-W3 oils)to test on the outboard engine secure test rig and on the OMC J70 outboard engine testrig. The result indicated that the trend of data was consistent with the trend of datafrom the test-bed for evaluating detergency of amphibious two-stroke gasoline engineoils. And the test-bed differentiated different oils distinctly.Selected different air-cooled two-stroke reference oils to test on the test-bed forevaluating detergency of amphibious two-stroke gasoline engine oils. The resultindicated that the detergency of air-cooled two-stroke oils was more excellent thanthat of water-cooled two-stroke oils (TC–W3 oils). And the detergency criterion ofamphibious two-stroke gasoline engine oils was established.Validating tests were experimented on lubricity test-bed, and smoke test-bed forevaluating amphibious two-stroke gasoline engine oils. The results were validated tobe correct.Used Visual C++ program language, the program for the lubricity proceduresfor evaluating amphibious two-stroke gasoline engine oils was developedindependently. This program could automatically real-time collect datafrom the system of test-bed and deal with the data, could improve themeasure precision, and relieve the test worker.Selected the US compound addictive (S833) for TC-W3 oils to confectthe oil that conformed to TC-W3 standards, namely standard oil. Servedthis standard oil for base oil to confect the amphibious two-stroke gasolineengine oils, through added some addictives to lower the smoke and lessen the deposits,at the same time, enhanced the formulation to keep its lubricity etc. Thenumber of amphibious oil samples was six.By analyzing the amphibious oil samples, sample 1 that conform to viscosityclass SAE 20 and sample 5 that conform to viscosity class SAE 30 were selected.Sample 1 and sample 5 were tested on the amphibious oil evaluating test-bed.The result indicated that sample 5 passed the detergency test and the lubricity test forevaluating amphibious two-stroke gasoline engine oils, but the smoke test. However,sample 1 passed all the tests of amphibious two-stroke gasoline engine oils, that is tosay, sample 1 conformed to the criterion of excellent air-cooled two-stroke oils (JASOFC oils) as well as conformed to the criterion of excellent water-cooled two-strokeoils (TC-W3 oils).
