    　More details

    Bio diesel fuel (BDF) used in diesel engines has a higher oxygen content than gas oil. In previous studies, performance tests using BDF in small diesel engines showed that that increased PM emissions are suppressed under conditions of reduced oxygen concentration. Elsewhere, the kinematic viscosity of BDF is higher than that of gas oil, which is considered to be disadvantageous for rendering the fuel spray finer. This study compared the effects on thermal efficiency and exhaust gas of changing the fuel injection pressure, which affects finer fuel spray, in a diesel engine using gas oil and BDF. The study found that the difference in operating characteristics depending on the fuel used is reduced when the fuel injection pressure is increased to 200 MPa. However, at lower fuel injection pressures, the exhaust gas component deterioration is suppressed when using BDF.
