Use of dual fuel between B10 and increasing syngas on the performance and emissions of a diesel-engine generator

The research is to study the use of diesel mixed to 10%biodiesel (B10) combined to increasing syngas from 76 to 125 lpm in dual fuel mode with a diesel-engine generator. In engine test, the speed was adjusted from 1,000 to 1,600 rpm. Syngas was produced from a downdraft gasifier, as the charcoal was used to the primary fuel. Results indicate that the use of B10 and increasing syngas on dual fuel gave higher engine performance than using B10, but the emissions were enormously increased with increasing syngas. However, the use of B10 and syngas at 125 lpm increased the fuel saving to 30.77% and 27.20%, and the electrical efficiency added to 13.90% and 10.59% as compared with B10 and diesel respectively. Dual fuel between B10 and syngas at 125 lpm can apply to the diesel-engine generator in the future. (paper)
