Abstract

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. 1. Introduction According to quoted by Classification Societies statistics 70% or so ma- rine diesel engines but mainly the larger bore destined for prop
