Modeling and Computational Analysis of Diesel Engine Working Process in Plateau Environment

Abstract

Using simulation software, numerical simulation and plateau tests are combined to create the plateau diesel engine process simulation model. External characteristics tests of the diesel engine, plateau simulation experiments and plateau vehicle tests are combined to verify the model. The maximum deviation of the results is less 10%. The simulation model is accurate, which provides a way to study plateau environmental adaptation of diesel engines.

Role of Altitude in Influencing the Spray Combustion Characteristics of a Heavy-Duty Diesel Engine in a Constant Volume Combustion Chamber. Part II: Impinging Diesel Jet

“…The schematic above is highly simplified, and it attempts to depict changes of the liquid–wall interactions and impinging flame morphology under different altitude conditions only based on the results discussed in this work. However, it can furnish the diesel engine community with a mental image to promote new thinking beyond the popular solutions, such as two-stage turbocharger systems, − alternative fuels, − oxygen enrichment of the intake air, − adjusted injection systems, − and advanced injection strategies, − to recover and improve the performance of diesel engines operating in plateau regions. Herein, we attempt to analyze two viewpoints.…”
