Engine Development

A comprehensive mechanical testing program was part of the development of the Diesel engine for the GEVO locomotive family. The test program has been developed under consideration of the demands of a railroad application. The program included both fired engine and component rig testing. Component rig tests were used to validate major components early in the design stage. Engine testing included measurements to validate the CAE models and allow detailed experimental development of components and subsystems. Several endurance runs have proven the reliability of the new engine.

This paper presents a review of the engineering testing program related to development of the PGT-25 gas turbine. The experimental methods employed and their capability of providing information for the tuning of the engine and its parts are discussed. Testing has continuously supported turbine design and development; integration of analytical and experimental procedures has proven to be efficient for successful final engine testing. Full load testing, using well developed instrumentation, has made it possible to know actual component behavior and engine performance in steady and transient states, over the entire speed and power range. The reliability of the machine has been assessed through the results of these tests.

Gas To Liquids

Sulfur free synthetic diesel fuels can be produced using gas to liquids (GTL) technology, and may prove useful as a substitute for conventional diesel fuels when oil reserves are depleted. With non-detectable amounts of sulfur and aromatics, these fuels should generate lower emissions and enable catalytic clean up. This paper presents the results of a durability test conducted on a Detroit Diesel Series 50 diesel engine-generator operating on two synthetic GTL diesel fuels. Besides providing a comparison of diesel emissions, the paper also provides a comparison of generator fuel efficiency and brake specific fuel consumption between the synthetic fuels and conventional diesel. Documented emissions include total hydrocarbons (THC), carbon monoxide (CO) and oxides of nitrogen (NOx). All tests on the diesel engine reported were conducted at the factory set injection timing. As the best performance of an engine on a particular fuel may be affected by injection timing, further tests of the synthetic fuels at different injection timings are needed and will be discussed in future work.

Abstract Results of this infrared study give strong qualitative support for the presence of quinones and support the presence of lactones. Considerable chemical reactivity is associated with the presence of these two groups. Absorption typical of phenols and ethers was obtained in the 1205–1195 cm−1 and 1275-1265 cm−1 regions; and it is suggested by this study that the oxygen not present in quinone, lactone, or phenolic form is present as aromatic ring-type ether groups.
