Low load combustion in medium sized medium speed diesel engine burning heavy fuel oil

摘要

This paper describes the results of the continuous low load combustion tests by burning the heavy fueloil in order to confirm the reliability of the medium sized medium speed diesel engine with a 260mmbore. To investigate the effect of the engine load on the exhaust smoke and the soot contamination inthe engine, the combustion tests are conducted on the variations of the continuous operation loads at0.2MPa and 0.4MPa in BMEP. The results indicate that the engine contamination with the sootdeposit increases as not only the engine load decreases, but also the operation duration increases.
