基于蓄能器原理的汽车尾气余热利用系统

Residual Heat Recovery System of Automotive Exhaust Based on Accumulator Principle

针对陆路交通主力军——汽车发动机的尾气余热白白浪费的现象,拟研究开发一套基于蓄能器原理的汽车发动机尾气余热回收存储与利用系统。利用设计的双循环特殊蓄能器对汽车运行过程中尾气排放管道壁产生的热量进行回收,将其转化为液压能储存在恒压蓄能器中,并设计一套与之相配的液压传动回路,利用回收的液压能作为车辆起动和制动的动力源。系统在实现节能的同时,也使汽车尾气余热回收利用的方式更加多元化和实用化。

For the waste phenomenon of exhaust residual heat of automobile engine,which is main land traffic tool,the recovery,storage and utilization system of residual heat was researched and developed based on the accumulator principle.The heat which generated in the exhaust pipe wall during the running of automobile was recycled by a special designed dual cycle accumulator and then was stored in a constant pressure accumulator after being transformed into hydraulic energy.By designing a set of matched hydraulic transmission circuit,the recovered hydraulic energy could be used as the power resource of starting and braking.The system realized energy reuse and made the automotive engine exhaust heat application more practical and diversified.
