柴油机高原可调增压技术

Adjustable Supercharging Technology for Diesel Engine at Plateau

分析普通废气涡轮增压技术应用于柴油机高原功率恢复的局限性。比较分析可变截面涡轮增压、相继增压、复合增压和多级涡轮增压4类典型可调增压技术的原理、与柴油机的匹配特性以及对柴油机性能的影响,研究不同可调增压技术在高原环境下应用的可行性,并提出二级可调增压技术是提高柴油机高海拔性能的首选增压技术。

The paper analyzes the limitation of common turbocharging technology applying in power restoration of diesel engine at plateau,compares the principles of 4 typical adjustable supercharging technologies: variable geometry turbocharging,sequential supercharging,compound supercharging and multi-stage turbocharging,and analyzes the matching characteristics and influence on performance of diesel engine. It also studies the feasibility of applying different adjustable supercharging technologies at plateau,and proposes that two-stage adjustable supercharging technology is preferred for improving the performance of diesel engine at plateau.
