The traditional combustion mode which utilized in the DI diesel engine has high and excessive emissions so the most wanted combustion is creating new modes which produce low combustion temperatures and low emissions. The main objective of the research is executing combustion, performance, and emissions attributes for PCCI-DI engine using blends of biodiesel and commercial diesel fuel blends for reducing the reactivity of the waste cooked oil and fossil diesel fuel mixtures. In this investigation, the waste cooked oil biodiesel is mixed with pure diesel fuel to formulate two blends by volume are 20% biodiesel 80% diesel (B20D80) and the other is 40% biodiesel 60% diesel (B40D60). The PCCI-DI engine methodology is activated after running the engine traditionally with direct injection for keeping stable running and prevents cold starting. The PCCI-DI operation insures that the charged mixture of a certain fraction of the supplied fuel is vaporized outside the engine manifold and the rested fuel quantity is conventionally burned before the TDC. However, the fuel blends that vaporized are adjusted at different premixed ratios at 20%, 25% and 30%, in that orders. The present investigation shows upgrades in all engine attributes. The obtained results of PCCI-DI technique at different premixed ratios shows a certain reduction for the peaks of the in-cylinder pressure, reduction in apparent heat release, rising in average brake thermal efficiency from 19.34% at conventional direct injection to 29.91% at PR3. In addition, reduction in average CO emission from 0.324% to 0.083% and reduction in average NOx from 559.3 PPM to 150.5 PPM. |
