Análise de falha de motor diesel de colhedora de cana de açúcar John Deere 9.0L

Abstract

Automotive maintenance is understood as the set of techniques and processes responsible for enabling a machinery performs its designated functions. Analysis of agricultural equipment failures in juice energy companies, such as Raízen, is a strategy that helps to reduce the cost of loss and/or damage to parts, since, once the problem is known, it is possible to draw up action plans to prevent it from occurring in the future. However, to be assertive, it is necessary to investigate the various components that make up the analyzed mechanical system. In this course conclusion work, the failure study of one of the key components for the operation of a harvester will be made: the diesel engine. The investigation will aim to identify the most frequent causes of failure of this engine and prevent the repetition of this fact in other parts. For this, the analysis will be based on the identification of damaged engine components, identification of impurities in the used lubricating oil, as well as the history of preventive and corrective maintenance already carried out. To gather and organize the information in priority, and to manage the study in a purposeful way, the Ishikawa management tool will be used. At the end of the study, it is expected to find the reason that caused the engine to fail, as well as to identify the GAP's or gaps that until then were not investigated and became a problem for the proper functioning of the engine, so that plans can be drawn up later. assertive actions in the programming of the component in question.
