Abstract

This study is about wear debris detection and analysis of automotive engine lubricating oil. The purpose of this study was to investigate wear debris produced by the sliding condition in automotive engine parts. Wear debris will be produced by the friction between two sliding automotive parts. This debris will cause the defect on automotive engine if not controlled properly. Thus, this study will helps the maintenance engineer to schedule the overhauled of the engine and prepare the spares and replacement of engine parts according to the amount and shape of wear debris. By using pin-on-disc machine, wear test experiment was conducted. From wear test, the data of coefficient of friction and friction force was collected from data logging system to be analyzed. A material was being selected based on the material that used frequently for automotive parts. The debris produced from the friction of the material selected and rotating disc from this machine were collected for analysis. Scanning Electron Microscopy (SEM) was used in analyzing the wear debris collected. The size of wear debris was measured from the image scanned by SEM. EDX analysis software was used to determine the composition of wear debris produced from wear test.
