摘要：
HCCI combustion is much sensitive to cyclic variations. The transient air/fuel ratio has an important effect on combustion characteristics. Fast CO2/CO, HC and NOx measurement systems were employed to detect the transient emissions and real time air/fuel ratio of an ethanol fueled DI-HCCI. Effect of real time air/fuel ratio on combustion characteristics was analyzed. Results show that real time air/fuel ratio of continuous combustion cycles fluctuates to the averaged value and follows the normal distribution. For high latent heat of ethanol, the decreasing of temperature by increasing fuel injection quantity postpones combustion phase and increases combustion duration.
