Abstract: In this paper to investigate the effect of fuel injection pressure in a diesel engine running on microalgae in naturally aspirated, direct injection diesel engines, parameters of pure diesel (D100), 80% diesel + 20% microalgae spirulina (B20), 60% diesel + 40% microalgae spirulina (B40) and pure microalgae spirulina biodiesel (B100). The fuel injection pressures (FIP) varies from 18 to 26 MPa and stationary injection timings. The result shows that optimum effect can be obtained in 22 MPa FIP, with B20 bio-diesel and increasing the percentage of spirulina biodiesel, there is a decrease in exhaust gas temperature, while there is a marginal increase in SFC. The remarkable emissions lower 22.9% of particulate matter and there is an increase in CO2 emission by 4% in the blend ratio B20% at full load operating condition.
