提升大背压柴油机功率的增压系统研究

Research of Supercharging System for Improving the Power of Big Backing Pressure Diesel Engine

为了使现用柴油机同时适应环境压力下和大背压下的使用需求,针对现有柴油机和选配的增压器,利用AVL-Boost软件对放气增压系统和相继增压系统进行了分析比较,结论表明:通过对现有增压系统的适量改造,可以较大幅度地提高大背压柴油机功率,同时适应环境压力下和大背压下的使用需求。

With the purpose to make the existing diesel engine adapt to both environmental pressure and big backing pressure, AVL- Boost software is employed to study supercharging system with wastegate valve and sequential supercharging system. The analysis results show that by improvement of existing supercharging system, the power of big backing pressure diesel engine is largely enhanced, and may satisfy the application requirements under both environmental pressure and big backing pressure.
