Abstract

This paper discusses the impact of three study cases that change with different values: the first case is four initial temperature values [313, 323, 333, and 343 K], the second case is three equivalence ratios [0.2, 0.3, and 0.4], and the third case uses various concentrations of biodiesel and diesel mixes [D100, B20, B40, B60, B80, and B100]. The purpose is to use the Chemkin software program to determine the effectiveness of each case in the HCCI combustion process. The results included cylinder pressure, cylinder temperature, accumulated gas phase heat release, heat loss rate, UHC, and mole fractions of O₂, CO, CO₂, diesel [NC₇H₁₆] and biodiesel [C₅H₁₀O₂]. the conclusion that biodiesel blends enhance the characteristics of the HCCI engine as compared to conventional diesel.
