| Abstract:To solve the problem that the power of a one-stage turbocharging diesel engine decreases seriously when working at high altitude, 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 intercoolers were predicted and analyzed. The analysis results indicate good adaptability of the two stage turbocharging diesel engine at variable altitudes. |
