| Abstract | ||
| This study investigates the influence of cetane number improver on performance and emissions of a DI four stroke diesel engine fueled with biodiesel (derived from corn oil)–diesel blend fuel. Different percentages of cetane number enhancer (2, 4, and 6%) were added to blends. The results show that: the brake specific fuel consumption (BSFC) increased compared with diesel fuel. The brake thermal efficiency (BTE) improved remarkably, the enhancement achieved was about 6.1% on BTE of diesel fuel with adding 6% of CN improver to B20. NOx increased when CN improver was added to blends. The combustion characteristics of biodiesel–diesel blend fuel at large load may be resumed to diesel fuel by CN improver, but some difference exists at lower load yet. | ||
