Statistical corrosion evaluation of nozzles used in diesel CRI systems

► Corrosion densities at these ten different areas of the injector were investigated. ► The most critical area of the nozzle is the nozzle stem. ► Corrosion density decreases with new generations of CRIN and CRIP nozzles. ► Corrosion level increases with increases in sulfur content in diesel. ► Biodiesel is more corrosive fuel than diesel.
