In 1995, the pipeline industry and its research councils (GRI & PRCi) in conjunction with Woodward Governor and Colorado State University developed a revolutionary technology focused on improving incylinder air/fuel mixing. This was the first step in “high-pressure” (500 psig) fuel injection (HPFI) for direct injected large bore engines. Since that time, this technology has become production equipment installed on hundreds of engines and is the standard in low emissions retrofit packages for these large bore engines. Many papers and case studies have detailed the success seen on specific engine models and at very low NOx (oxides of nitrogen) levels. A side benefit that had been discussed and analyzed with limited qualitative data is the long term effects to the engine itself. We can all theorize that more consistent combustion leads to less detonation and misfire and more consistent loading of the mechanical drive train. So, from this information we would expect to minimize wear on these major components and see a significantly longer operating life. Additionally, we would expect to see positive effects on day to day operation and maintenance. Now, after ten years and thousands of hours of operation, operators are starting to go through their engine overhaul lifecycle and are beginning to see the long term benefits of this technology that had been expected early on. This paper will analyze the findings from the pilot and early commercial installations to document these long term affects and substantiate the theories that we have all expected. An in-depth review of maintenance requirements from before and after the retrofits, including maintenance now required with the new systems is presented. A high level review of the history of HPFI will be discussed including the “add” on technologies that have become the standard in the installation of this equipment.
