摘要
本文从汽油机油氧化、磨损机理上概述了汽油机油在降解过程中 ZDTP 的作用和它与氧化、磨损的关系。所提出的测定四球机达到卡咬时间的试验方法可模拟凸轮和挺杆的润滑状态,试验过程中既有氧化又有磨损,可为汽油机油的研制提供可靠的氧化、磨损性能数据。
The effect of ZDTP and its relation with oxdation and wear during thedegration of gasoline engine oil are briefly discussed on the basis of oxdationand wear mechanism of motor oil.The proposed testing method,i.e.to mea-sure the time required for seizure to occur on four ball machine,is able tosimulate the lubrication of the cam and lifter.Both oxidation and wear takeplace during the test.Reliable information on oxidation and wear useful forgasoline engine oil formulation can be obtained by this method.
