Combined impact of injection pressure and combustion chamber geometry on the performance of a biodiesel fueled diesel engine

- Investigates the effect of injection pressure and combustion chamber design for biodiesel operation.
- Tests were carried out using 20% Pongamia biodiesel blend with diesel and diesel.
- Toroidal Re-entrant (TRCC) and Hemispherical combustion chambers (HCC) were used.
- Tests were carried out at different injection pressures of 185, 200, 210, 220, and 230 bar.
- TRCC has shown improved performance and emission characteristics at 220 bar.
