Effect of boundary conditions and <i>n</i>-heptane on methyl decanoate HCCI combustion and emission based on two-stroke diesel engine

The initial boundary conditions, combustion, and emission characteristics of methyl decanoate (MD) mixed with different proportions n-heptane (N-Hep) for homogeneous charge compression ignition (HCCI) are studied in this work. MAN B&amp;W 6S70MC two-stroke diesel engine was used as the model reactor. results showed that, when equivalence ratio is 0.48, NO emissions MD N-Hep HCCI combustion process decrease temperature. temperature determined to be 380 K. At same time, increase pressure, pressure 1.3 atm. also indicate at a certain temperature, total mole fraction fuel, CO2, NOx reaction rates, reduced significantly percentage mixing combustion.
