FUEL 11 |
| Biodiesel, derived from plant matter, shows great promise to supplement hydrocarbon based diesel fuel. The performance of biodiesel in standard diesel engines has been extensively researched. However, very little research has been done with biodiesel in homogeneous charge compression ignition (HCCI) engines. The primary challenge to the development of the HCCI engine is expanding the operating range and understanding how fuels affect combustion is essential to developing an effective control strategy. In the present study, experiments have been carried out to assess the performance of a 100% biodiesel fuel (methyl ester), derived from soya oil, compared to three other hydrocarbon diesel fuels in an HCCI engine. Performance, emissions, and combustion characteristics have been examined and compared. Findings indicate that biodiesel requires earlier combustion phasing for peak efficiency, a hotter charge for ignition, burns more rapidly, and exhibits higher combustion temperatures than the HC based fuels. Total HC, CO, and NOx are all higher for the biodiesel. |
