乘用车发动机舱关键零部件的布置研究

乘用车发动机舱布置了整车的心脏-动力总成,以及进气系统、排气系统、冷却系统、燃油系统、悬置系统、蓄电池、转向系统、制动系统、空调系统以及各系统相关的管路附件等。在前舱有限的空间里不仅要摆放下这些部件,还要考虑到发动机的高温给周围部件所带来的影响,以及运动部件之间可能发生的静态或动态干涉,还要满足相关法律法规的要求,所以各系统部件在前舱中的合理布置就显得尤为重要和关键。主要阐述了动力总成及主要系统在布置中应考虑的因素。

Research on Key Components Package and Layout in Passenger Car's Engine Bay

In passenger car＇ s engine bay, there was packaged the vehicle＇ s heart-engine assembly, and air intake system, exhaust system, cooling system, fueling system, engine mounting brackets, battery, steering system, brake system, air-conditioning system, and all kinds of pipelines etc. In such limited space, not only all of these parts should be packaged, but also the effect of engine＇ s high temperature, basic dynamic and static clearance should be considered, and law requirements should be met. So, it is very important for logical package. It was mainly described which factors should be considered in engine bay package .
