基于等效等熵指数的燃烧始点实时反馈与控制
(2020) In Jilin Daxue Xuebao (Gongxueban)/Journal of Jilin University (Engineering and Technology Edition) 50(4). p.1160-1168- Abstract
In order to reduce cycle-to-cycle combustion phase fluctuations, a new control platform with functions of cylinder pressure acquisition, combustion states feedback, combustion control and engine control is developed. A novel Start of Combustion (SOC) detection algorithm based on the first derivative of the equivalent isentropic index is presented. Both next-cycle and in-cycle SOC control strategies are introduced. Experimental results demonstrate that the detection method is able to detect the real-time SOCs. The next-cycle control strategy according to the profiles of the heat release rate can control the SOC phase to its target and reduce cycle-to-cycle SOC phase fluctuations. The in-cycle control strategy can keep the consistency of... (More)

The next-cycle control strategy according to the profiles of the heat release rate can control the SOC phase to its target and reduce cycle-to-cycle SOC phase fluctuations. The in-cycle control strategy can keep the consistency of the SOC phase of the main injection under different exhaust gas recirculation rates.
