Experimental and Theoretical Assessment of a Diesel Engine Using Different Palm Oil Methyl Ester (POME) Blends at Different Compression Ratios
In the variable compression ratio (VCR) diesel engine test setup, the palm oil methyl ester (biodiesel) was tested with diesel in varying quantities. The combustion and emission properties and the performance of diesel engines powered by biodiesel blends were examined and compared with conventional petroleum diesel. For combustion analysis, the engine’s cylinder pressure profiles, mass fraction burned, start, and end of combustion while operating on various biodiesel blends under varying loads were acquired at CR 16, 17, and 18. B5 showed a higher quality of combustion in the cylinder pressure profile at zero load than B10, and as the load increased, the cylinder pressures for both B5 and B10 were nearly equal. Furthermore, it was discovered that brake thermal efficiency rises when load increases, but brake-specific fuel consumption falls. In the load range of 0–25% at compression ratio 18, B5 requires less brake-specific fuel than B10 and diesel. Compared to B10 and diesel, B5 exhibited the highest brake thermal efficiency at high loads at a compression ratio of 17. The emission of HC and CO was reduced at higher CR for B10 and B20, but the NOx formation was higher at higher CR.
