Maintenance Limits To Marine DieselEngines Fuel Injectors On Board Ships

As recorded by Classification Societies, statistics indicate that up to 70% percent of major marine diesel engines combustion space components suffer breakdown due to poorly operating fuel injectors. The paper draws the attention of marine engineers to the complexity of fuel injectors production and their re-conditioning. Methods of proper and skilled worn fuel valve nozzles renewal are discussed. The possibilities and limitations regarding the reconditioning of fuel valve nozzles on board ship are highlighted with the principal aim of making the marine engineer on board aware of existing constraints on fuel injectors maintenance.
