The Importance of Fuel Injector Valve to Support Main Engine Performance Ship MV. Meratus Medan I

Abstract

The injector functions to atomize the fuel into the engine's pressurized combustion chamber with a control mechanism that allows regulation of the amount of fuel atomized into the combustion chamber. Incomplete combustion of the injector is indicated by the appearance of black smoke in the chimney. The research method used in this thesis is qualitative. Data sources were obtained from primary and secondary data collection. Data collection techniques through observation, interviews, literature study and documentation. The data analysis technique used in this research is the shell method. They were testing the validity of the data using the triangulation method. The research results stated that the factors causing less than optimal performance on the injector were the discovery of crust on the tip of the nozzle, the nozzle and spring being damaged, the working hours on the injector had exceeded the limit, the quality of the fuel was not good, and there was water and mud content. The efforts include checking and testing the injectors, always carrying out a planned maintenance system according to the manual book and improving the fuel quality from the presence of water and mud content by running a purifier
