Abstract

The combustion phase of a homogeneous charge compression ignition (HCCI) engine fueled with n-butanol/diesel blends was investigated on a 2-cylinder direct injection naturally aspirated and four-stroke engine at speed of 1000 r/min under different blending ratio and excess air ratio. The results show that with the increase of n-butanol/diesel volume content in the blends, the ignition timing of HCCI combustion retards under constant excess air ratio and the combustion duration shorten. When the blending ratio keeps constant, the the ignition timing brings forward with decrease in excess air ratio while the combustion duration has no significant difference, except for the blending ratio of 95%.
