Availability and durability of fuel injection equipment are major problems in burning coal slurry fuels in fuel-injected type internal combustion engines. Initial testing with commercially available equipment indicated a very short life (approximately four minutes) due to plunger/needle scoring, heating, and lack of lubrication. Design changes to the equipment did not appreciably improve the equipment life. An air-assisted coal slurry injector, however, was designed and tested for over 100 hours of trouble-free operation with 40 percent coal plus DF-2 slurry fuel. The droplet size/size distribution study indicated much finer spray as compared with the solid injection system.
