At present, diesel injection systems are desirable due to their advanced technology and balance between performance and consumption. However, there are still some problems that this technology is not yet able to overcome. One of these is corrosion. In the Common Rail Injection (CRI) system, one important component subject to corrosion attack is the nozzle. This part of the injector is the only component that is directly subject to high thermal load and chemical or electrochemical reactions with its surroundings in the combustion chamber. However, the main task of the injector nozzle is to properly inject high-pressure fuel into the combustion chamber while withstanding outside effects such as high temperature, high pressure, cavitation, and corrosion, among others. The aim of this study is to investigate the corrosion behaviors of nozzles with different runtimes, temperatures, and fuel types. In addition, corrosion behaviors are investigated on different sides of the nozzle. As a result, the relationships between corrosion and runtime, temperature, and different fuel types are described. All interpretations are derived from statistical results based on the experimental data. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.
