大马力高原型推土机进排气系统设计

Intake/Exhaust System Design of High-Land Bulldozer

摘要: 进排气系统的结构及匹配状况直接影响推土机的动力性、经济性和排放性，恶劣的高原环境对大马力推土机进排气系统的要求更为苛刻且目前还没有可借鉴的成熟的指导性资料。因此，本文从高原环境对进排气系统影响出发，结合自身开发大马力高原型推土机的设计工作经验，总结了高原环境对推土机动力系统的影响情况及设计人员可采取的应对措施，为以后类似大马力高原型工程车辆的进排气系统优化设计和性能提升提供参考。

Abstract: The structure and matching state of intake/exhaust systems directly affect the power, economy and exhaust of Bulldozer. Execrable working circumstance puts severe requirements on the in-take/exhaust system of high-land bulldozer, and also there is no reference to the mature guidance information. Therefore, based on the influence of high-land environment on the intake/exhaust system, combined with work experience of author, the influence of plateau environment on the dynamic system of bulldozer is summarized, which will provide a strong theoretical basis for the study of intake/exhaust system and performance improvement of gigantic horsepower bulldozer in the future.
