摘要
针对某一级增压柴油机在高海拔地区工作时功率大幅下降的问题,基于GT-Power软件建立了二级涡轮增压中冷柴油机的工作过程模型并经试验数据验证;采用所建立的模型预测分析了二级增压柴油机在变海拔条件下的进、排气参数,以及增压中冷等部件的性能参数的变化规律。分析表明:二级增压柴油机具有良好的变海拔适应性。
To solve the problem that ously when working at high altitude, the power of a one-stage turbocharging diesel engine decreases seri- GT-Power software was adopted to establish the operation model of two-stage turbocharging and intercooling engines, and then the model was verified with experiment data Based on the model, the change rule of intake and exhaust parameters of two-stage turbocharging diesel engines at variable altitudes, as well as the performance parameters of parts such as compressors and in- tercoolers were predicted and analyzed. The analysis results indicate good adaptability of the two stage turbocharging diesel engine at variable altitudes.
