Abstract
It is important in determining whether we get low temperature heat release (LTHR) or not For instance, if we ran the engine with boosted intake pressure and low temperature, we could see LTHR but LTHR disappears if the same fuel is run with low intake pressure and high intake termperature. Thus whether we see LTHR in HCCI tests depends much on the operating conditions. The purpose of this study is to obtain fundamental knowledge about the effect of Intake gas Pressure and Temperature on HCCI combustion. The computational work is conducted using a multi-zone model and detailed elementary reaction mechanism. In this study, we use PRF which is the mixture of n-heptane and iso-octane.We can see the deference of the effect of intake gas pressure and temperature in HCCI engine between fuel structure.
