Provide the railroad industry and the locomotive manufacturers a summary of lessons learned in the automotive industry regarding use of biodiesel. Close the knowledge gap between those who have been participating at ASTM International over the last two decades and those who have not. Merge the activities of the two groups, bring the railroads to ASTM, and eliminate duplication of efforts. Lack of participation by any group in standard setting efforts can result in fuel specifications that lack components for a particular application.
This new J document provides a general summary of the experience with biodiesel in the automotive industry where significant research has been conducted over 20 years. Recently, the railroad industry and the locomotive manufacturers have experienced similar concerns. The purpose of this document is to provide them and other practitioners dealing with biodiesel, with the knowledge and a tool to evaluate if additional research is warranted regarding their specific application. Engine performance, emissions, material compatibility, fuel storage, and long term effects are discussed. Users of any fuel including biodiesel blends should contact their engine manufacturer for advice regarding fuel/equipment compatibility.
