Mustholiq, M.M., M.Mar.E, Supervisor II: Sri Purwantini, S.E., S.Pd., M.M. The main engine has a very important role to support the smoothness of the voyage of the ship, one of the main support in the parent machine is a Bosch pump, which serves to push the fuel into the injector for subsequent injection injector fuel in to the combustion chamber, in this study the authors will discuss about Bosch pump interference to injector performance. The research method used is qualitative, in determining the priority of the problem to be resolved, the research using an approach tool that is SWOT method by giving the value 1-4. Sources of data that the authors use is the primary and secondary data sources, while the method of withdrawal of conclusions that the author uses is by comparing the actual situation with the results of the author's thorough theory. From the results of research conducted problems that occur is the occurrence of interference on the Bosch pump which causes injector performance becomes not maximal and this is due to blister plunger on the bosch pump that resulted in plunger and barrel is not precise. The impact of blister plunger on the bosch pump results in a decrease in plunger plaque on the barrel so that the resulting fuel pressure becomes reduced. Strategies on the problem are the maintenance and repair of the bosch pump, optimizing the fuel system to keep the fuel in a clean and periodic maintenance to the bosch pump and other machinery so that the engine and its components reach at least the economic life Keywords: Bosch pump, Injector, Main Engine
