摘要
The prediction of auto-ignition delay times in HCCI engines has risen interest on detailed chemical models. This paper describes a validated kinetic mechanism for the oxidation of a model Diesel fuel (n-decane and a-methylnaphthalene). The 3D model for the description of low and high temperature auto-ignition in engines is presented. The behaviour of the model fuel is compared with that of n-heptane. Simulations show that the 31) model coupled with the kinetic mechanism can reproduce experimental HCCI and Diesel engine results and that the correct modelling of auto-ignition in the cool flame region is essential in HCCI conditions.
