Experimental study on emission characteristics of HCCI operation with n-heptane

摘要：

　　Homogeneous Charge Compression Ignition (HCCI) is a new combustion mode with higher thermal efficiency and lower emission.With the recent development of experimental and theoretical investigations,HCCI operation for high cetane number fuels has attracted more attention.As a reference fuel,n-heptane is very easy to be ignited for high cetane number and shows obviously two-stage heat release in homogeneous charge compression ignition process due to chemical properties.HC,CO and NOx emissions of n-heptane HCC1 combustion with intake temperature and excess air coefficient are studied in this paper.Intake temperature and excess air coefficient have a great impact on HCCI combustion and provide important approaches to widen HCC1 operating range.
