Development of residual fuel capability for caterpillar medium-and-high-speed engines
Technology from a multi-phase development program is providing residual fuel capability for Caterpillar high-speed 3500 Family and medium-speed 3600 Family engines. Data from an extensive series of laboratory tests on a 2-cylinder 3500 Familiy engine (3502) has provided first-hand knowledge of the residual-fuel-related problems and solutions over a wide range of residual fuel impurities. These controlled laboratory tests have quantified the effects of various residual-fuel-related variables. Empirical equations have been developed for predicting the life of cylinder liners and exhaust valves as a function of residual fuel impurities and design configurations. Laboratory tests on a single cylinder 3600- Family engine(3601) have verified that the results from the high-speed 3500 Family engine also apply to the medium-speed 3600 Family engine. The best residual fuel design configurations identified from the 3502 and 3601 tests have been successfully demonstrated in the laboratory on a 6-cylinder 3600 Family engine (3606). These results indicate that the 3500 and 3600 Family residual fuel engines will meet or exceed the current residual fuel performance and life goals. Residual fuel field experience is providing longer-hour verification of the laboratory results. On-going development incorporating ceramic-coated components is expected to allow components in the 3500 and 3600 Family residual fuel engines to eventually approach current diesel-fuel components life, even when operating on the most severe residual fuels.
