低压EGR发动机冷却系统设计方案

The Cooling System Design of Low Pressure EGR Engine

在代号为GEN的传统增压发动机上应用外部冷却EGR技术对冷却系统进行优化,所以我们主要介绍的是在概念设计阶段针对冷却系统的一系列设计校核,主要包括Cooler的布置和选型以及水泵性能校核,为EGR冷却系统概念设计提供设计思路。

The cooling system for the application of external cooling EGR technology on a traditional turbocharged engine named GEN need to be optimized, so this paper mainly introduces a series of cooling design and check in the conceptual design phase, mainly including： the arrangement and type selection of the cooler and water pump performance check, which provide design ideas for EGR cooling system concept design.
