蒸发燃料处理系统
摘要：
本发明公开了一种蒸发燃料处理系统。净化泵安装在净化管道中，所述净化管道形成在罐的内侧与进气通道之间连通的净化通道。当进气通道的压力(P1)等于或小于预定压力(P10)时，大于预定净化量(Mpm)的大量的蒸发燃料引入进气通道中。此时，泵电力供应装置将相对少量的电力供应到净化泵以使得净化泵运行。当进气通道的压力(P1)大于预定压力(P10)时，净化泵被驱动以将蒸发燃料泵送到进气通道中。那时，泵电力供应装置将相对大量的电力供应到净化泵。
摘要（英）：

The invention discloses a evaporation fuel processing system. A purge pump is installed in a purge conduit, which forms a purge passage that communicates between an inside of a canister and an air intake passage. When a pressure of the air intake passage is equal to or smaller than a predetermined pressure, a large quantity of evaporative fuel, which is larger than a predetermined purge quantity, is introduced into the air intake passage. At this time, a pump electric power supply device supplies a relatively small amount of the electric power to the purge pump to run the purge pump. When the pressure of the air intake passage is larger than the predetermined pressure, the purge pump is driven to pump the evaporative fuel into the air intake passage. At that time, the pump electric power supply device supplies a relatively large amount of the electric power to the purge pump.
