Research Progress of Chemical Kinetics Mechanism of Internal Combustion Engine Fuel

he research progress of detailed chemical kinetic mechanism for internal combustion engine fuel such as methanol,ethanol,n-heptane(diesel fuel substitute),isooctane(gasoline substitute),methyl decanoate(an alternative of bio-diesel fuel),was summarized.The main method of simplifying the reaction mechanism of complex reaction system in the fields of international combustion and reaction kinetics and the corresponding research results of these methods were introduced.The theoretical basis and the advantages and disadvantages of simplifying methods based on different mechanism were analyzed and compared.In view of the situation that the fossil fuel mixed with the alternative fuel in internal combustion engine application,the chemical kinetics mechanism of multi-component fuel was introduced and the limitation of building the multi-component mechanism was analyzed.For the deviation phenomena of new mechanism meeting the detailed chemical kinetic mechanism of different components,the mathematical method was usually used to correct the reaction rate constant so as to improve the accuracy of mechanism.
