Development and Validation of a Reduced Chemical Kinetic Mechanism for HCCI Engine of Biodiesel Surrogate
摘要
Abstract
A simplified mechanism of methyl decanoate and n-heptane blend was developed for a homogeneous charge compression ignition engine built from a previously reported detailed mechanism of a methyl decanoate and n-heptane.The simplified mechanism with 113 species and 306 reactions was developed using path flux and temperature sensitivity analyses.The simplified mechanism was validated against the experimental data of ignition delay time,in-cylinder pressure,and CO emissions.Results show that the simplified mechanism not only coincides with the ignition delay time of the methyl decanoate and n-heptane,but also the CO emissions,and can reproduce the variation of in-cylinder pressure.The simplified mechanism can be further validated by comparison with the detailed mechanism,which shows that the simplified mechanism can coincide with the in-cylinder pressure and temperature,and can reproduce the variation tendency of the core components.Thus,the reduced mechanism is a reasonable one.关键词
