The Effect of Biodiesel Composition on Engine Emissions from a DDC Series 60 Diesel Engine

2/28/2003

Certificaation fuel runs exhibited a mean NOx emission level of 4.59 g/bhp-h (+/-.053) with no significant drift over the four month test program. PM emissions averaged 0.261 g/bhp-h (+/-0.019). A small downward drift in PM emissions was evident (11% over the course of the project). Thus, no correction for drift was applied to the NOx emissions data but a small correction wass applied to PM.

Using Unmodified Vegetable Oils as a Diesel Fuel Extender: A Literature Review

9/22/2002

This paper is a review of literature concerning using vegetable oils as a replacement for diesel fuel. The term vegetable oils as used in this paper refers to vegetable oils which have not been modified by transesterification or similar processes to form what is called biodiesel. The oils studied include virgin and used oils of various types including soy, rapeseed, canola, sunflower, cottonseed and similar oils. In general, raw vegetable oils can be used successfully in short term performance tests in nearly any percentage as a replacement for diesel fuel. When tested in long term tests blends above 20 percent nearly always result in engine damage or maintenance problems. Some authors report success in using vegetable oils as diesel fuel extenders in blends less than 20 percent even in long term durability studies. Degumming is suggested by one author as a way to improve use of raw oils in low level blends.

Washington Metropolitan Area Transit Authority: Biodiesel Fuel Comparison Final Data Report

8/15/2002

The West Virginia University measured the exhaust emissions from a Flxible Transit bus with a 1990 Cummins L10 engine operated on standard federal type-1 deisel fuel (D1), ultra-low sulfur type-1 diesel fuel (ULSD1) and on a blend of 20% biodiesel and 80% ULSD1 fuel (BD20). During the ULSD1 and BD20 tests the transit bus was equipped with an Engelhard DPX catalyzed particulate filter. The vehicle was exercised over a chassis dynamometer test cycle that was developed from data logged from WMATA buses during normal passenger service in the Washington D.C. Metropolitan Area. All measurements were made in accordance with the guidelines set forth in the Code of Federal Regulations CFR40 Part 86 Subpart N.

Technical Barriers to the Use of Ethanol in Diesel Fuel

11/1/2001

The objectives of this study are to examine the status of ethanol-diesel blends and to identify barriers and technical gaps that hinder rapid introduction of these fuels into the market. The results of this assessment and planning process will allow the Department of Energy (DOE) to understand the issues facing the industry and to determine if and how DOE involvement might assist in overcoming the identified barriers. This document includes a brief description of ethanol production, distribution, and storage as background information. This is followed by a description of ethanol-diesel blends (e-diesel) and the properties of these fuels. Engine performance and regulatory requirements are also described. Potential technical barriers are noted in each of these areas and summarized at the end.
