Free 32-Page Report Details Test Results On New Fuel Efficient EMD Diesel

Electro-Motive Division of General Motors, LaGrange, 111., has released a progress report which outlines the results of a threeyear series of tests conducted by EMD on blended fuels. Contained in the report are what are believed to be among the first electron microscope photographs of catalyst fines.

The evaluation of low quality distillate, as well as low quality distillate-residual blends, has been the subject of in-house and field evaluation. EMD's study of blended fuel goes back 25 years. This study has been intensified in recent years. The studies have concentrated on the effects of poor quality distillates. More recent in-house studies have focused on the impact of today's poor quality residuals and their influence on relatively low viscosity blends in the 200 SRI range.

Testing of blended fuels continues in the field, and new test facilities are to be operational later this year.

T.J. Lehman, EMD marine sales manager, said: "We recognize that as the leading supplier of medium-speed diesels to the marine market, we have an ongoing responsibility to our customers, so we have tried to provide them with a realistic view of blended fuels." The report contains a full explanation of EMD blended fuel test procedures and includes a section completely describing the configuration of the new 645 engine.

Three tests were conducted, A, B and C.

The report contains a description of each test and a detailed explanation of the results of all three tests. This includes graphs and photos illustrating the highlights of past test inspections and summaries of data analysis.

This very informative report concludes with a summary of all test results covering the areas of catalyst fines, vanadium carbon residue and sulphur content.

Recommendations are included on prospective fuel limits, use of different fuels, centrifuging/filtering, fuel systems, lubricating oils, and fuel terminology.
