  4. Results Comparison of Sunflower and Rapeseed Oils with common Diesel Fuel (in g/kWh, measured by ESC) Heat Release of Different Fuels Department of Energy Engineering

  5. Utilisation of high proof grade crude alcohol in low-scale dual fuel diesel engine Related research result to topic No. 4 and 115 (Identify/develop promising technologies capable of controlling HC emissions from lean-burn engines (esp. Diesels) at low exhaust temperatures (as low as 150c) characteristic of advanced combustion processes, such as PCI and HCCI, Novel combustion systems for multi-fuel engines.) Alcohol Injector (primary fuel) Diesel Fuel Injector (Secondery fuel) Department of Energy Engineering

  6. Benefits of the dual fuel diesel engines • High compression ratio therefore high efficiency, • Qualitative control, therefore high efficiency on part load, • Flexible for fuels, (crude alcohol, biogas, methanol,…..) • Decreasing PM, • ….. Department of Energy Engineering
