主动式燃料蒸气净化系统及使用该系统的方法
摘要：
本申请提供一种主动式燃料蒸气净化系统及使用该系统的方法，所述主动式燃料蒸气净化系统包括：具有涡轮机以及压缩机的涡轮增压器；碳罐，其收集燃料蒸气；净化泵，其泵送收集的燃料蒸气；主净化管线，其连接碳罐与所述净化泵；第一净化管线，其从所述主净化管线分支并且连接到位于压缩机的下游的进气歧管；第二净化管线，其从所述主净化管线分支并且连接到位于压缩机的上游的进气管线；净化控制电磁阀，其分别布置在第一净化管线与第二净化管线中；碳氢化合物传感器，其测量碳氢化合物的量；压力传感器，其测量所述净化泵的上游压力和下游压力；以及控制器，其基于碳氢化合物的量以及净化泵的前端的压力和净化泵的后端的压力控制净化泵的操作。
摘要（英）：

An active fuel vapor purge system includes: a turbocharger having a turbine and a compressor; a canister collecting fuel vapor; a purge pump pumping the collected fuel vapor; a main purge line connecting the canister and the purge pump; a first purge line branched from the main purge line and joined to an intake manifold at downstream of the compressor; a second purge line branched from the main purge line and jointed to an intake line at upstream of the compressor; purge control solenoid valves respectively disposed in the first purge line and the second purge line; a hydrocarbon sensor measuring an amount of hydrocarbon; a pressure sensor measuring an upstream pressure and a downstream pressure of the purge pump; and a controller controlling operation of the purge pump based on the amount of hydrocarbon and pressures at a front end and at a rear end of the purge pump.
