THE USE OF SLURRY FUEL IN A DIESEL ENGINE

The Southwest Research Institute, U.S.A., is carrying out a research programme, funded by the U.S. Dept. of Energy, on hybrid fuels derived from combinations of different energy sources. The objectives are to identify possible components for such fuels, determine what processing they require, evaluate their performance in existing Diesel engines, ascertain what engine modification may be needed, and examine the effect on engine performance. The programme includes the investigation of emulsions, solutions, and slurries. The present article is confined to an account of tests that are being conducted on a variety of components for hybrid fuels, including cellulose, starches, vegetable oils (peanut oil and cottonseed oil), and carbon-containing materials (in particular, coke and carbon black). These are combined, in various proportions, with Grade 2 Diesel fuel to form (except for the vegetable oils) slurries. A total of 29 formulations are being tested in a single-cylinder direct-injection Diesel engine running at various loads at 1000, 1500, and 2000 rpm. The main items under consideration are adequate delivery of the various blends, and their performance and emission characteristics. The experimental techniques and equipment are described, and some results are presented and discussed. The tests, which are still in progress, are being run in two phases, but only a 10% carbon black and a 20% cellulose formulation have so far been put through the second phase. However, it has already been shown that it is possible to operate Diesel engines on slurries and solutions, and of the components tested the most promising appear to be coke, carbon black, and the vegetable oils.
