Analsis penyebab kerusakan injector main engine dikapal mt griya sunda

Abstract

The injector is a vital component of the main engine that functions to atomize fuel into the combustion chamber to ensure optimal combustion. Damage to the injector can result in incomplete combustion, leading to reduced engine performance, increased fuel consumption, and higher exhaust gas emissions. This study aims to analyze the causes of main engine injector damage on board MT. Griya Sunda and its impact on engine performance.This research employs a qualitative descriptive method. Data were collected through direct onboard observation, interviews with engine officers, and a literature study related to marine fuel injection systems. The collected data were analyzed to identify the causes of injector damage as well as corrective and preventive measures.The results indicate that injector damage on the main engine of MT. Griya Sunda is mainly caused by poor fuel quality, carbon deposit formation on the injector nozzle, and suboptimal maintenance practices due to limited spare parts and time constraints. The impact of this condition includes reduced engine power and increased fuel consumption. Therefore, strict fuel quality control, routine injector maintenance in accordance with the Planned Maintenance System, and adequate spare part support from the company are necessary to maintain optimal main engine performance.
