Research on Cooling Temperature Control of Internal Combustion Engine Based on Hydraulic Driving Technology

在最近的几年中,在设计车辆时,车头迎风的面积呈现出递减的趋势,其目的在于安上各类辅助性的装置,从而导致内燃机设备壳下的范围愈来愈小,但却加强内燃机的功能,导致热负荷愈来愈高,同时冷却及其系统对内燃机性能提出了更高的要求,包括驱动力、经济性、释放性、减噪性和总体协调性等。本论文阐述内燃机冷却温度的运行原理,基于液压驱动技术设计内燃机冷却温度控制系统,勾勒总体方案,界定液压驱动系统的核心液压组建及属性参数,分别从控制发动机温度和液压系统温度的机制来设计控制电控单元冷却温度的相关组件。

In recent years,the front windward area shows a decreasing trend,the purpose is to install various auxiliary devices,strengthening the function of the internal combustion engine,increasing the heat load,and cooling and its system put higher requirements for the performance of the internal combustion engine,including driving force,economy,release,noise reduction and overall coordination.This paper expounds the operation principle of the cooling temperature of the internal combustion engine,designs the cooling temperature control system based on the hydraulic driving technology,outlines the overall scheme,defines the core hydraulic formation and attribute parameters of the hydraulic driving system,and designs relevant components to control the mechanism of controlling the engine temperature and hydraulic system temperature.
