Diesel Additive Technology Effects on Injector Hole Erosion/Corrosion, Injector Fouling and Particulate Traps

Abstract

<div class="htmlview paragraph">Fuel additives can contribute to maintaining the performance of diesel engines in a variety of ways. This holds true for current and future engine technology.</div> <div class="htmlview paragraph">Fouling of indirect injection engines (IDI) has been studied at length. Fouling of direct injection engines (Dl) is less known and less well understood. Problems associated with Dl fouling and a proposed mechanism for it are discussed. Additive effectiveness in preventing injector fouling is confirmed.</div> <div class="htmlview paragraph">Injector hole corrosion/erosion, as experienced in the Cummins N14 engine, can be avoided by the appropriate additive chemistry.</div> <div class="htmlview paragraph">Particulate traps can also benefit from ashless additive technology aimed at increasing the time between regeneration steps, hence improving effective trap life.</div>
