相继增压柴油机瞬态切换喷油策略
The fuel injection strategy in the transient switching process of a sequential turbocharging diesel engine
摘要
Abstract
In light of the problems of the transient switching process of a sequential turbocharging diesel design,the multi-objective evolutionary algorithm was used to optimize the transient switching process of the TBD234V12 sequential turbocharging diesel design By taking the fuel delivery per cycle per cylinder in the cut-in delay time as the design variables,restraining the conditions of power and maximum cylinder pressure,generating the initial uniform population through using the Sobol sequence,and optimizing the fuel injection rate of the transient switching process by applying Paretos non-dominated sorting method,the fuel injection rate in the transient switching process of the sequential tuborcharging diesel engine was optimized.The results show that the fluctuation of speed and the soot decreased by no less than 88% and 79%,respectively.With the optimization of the fuel injection map in the transient switching process of the TBD234V12 sequential turbocharging diesel engine,the engines transient switching performance was improved.关键词
