低黏度汽油机油燃油经济性测试方法区分性研究

STUDY ON DISTINCTIVENESS OF FUEL ECONOMY TEST METHODS FOR LOW VISCOSITY GASOLINE ENGINE OIL

随着现行节能和排放法规的日益严格,机油节能越来越受到汽车厂商的重视。GF-6汽油机油规格对机油节能提出较高要求,使用一种台架来评定用于多种发动机的润滑油的节能性能并不具备广泛的代表性,因此针对特定的某型号4缸发动机建立了一套能准确评价汽油机油节能的评定方法,并开展台架试验,将台架试验结果与SRV模拟试验考察汽油机油摩擦性能的结果进行对比。结果表明,建立的台架试验测试方法具有很好的区分性和重复性,适用于评价低黏度汽油机油的燃油经济性。

With the tightening of current energy-saving and emission regulations,the energy-saving of engine oil has attracted more and more attention by automobile manufacturers.GF-6 gasoline engine oil specifications put forward higher requirements for energy saving,and it is not widely representative to use a bench to evaluate the energy saving performance of lubricating oil used for various engines.Therefore,a set of evaluation methods that can accurately evaluate the energy saving of gasoline engine oil was established for a certain type of 4-cylinder engine,and bench tests were carried out,and the results of friction performance of different oil formulations were compared with those of SRV simulation tests.It is concluded that the established bench test method has good distinctiveness and repeatability,and is suitable for evaluating the fuel economy of low viscosity gasoline engine oil.
