双燃料车辆的LPG充补系统
Abstract:
本申请公开了一种双燃料车辆的LPG充补系统。LPG充补系统可以被构造成在外部温度很高的情况下(例如在炎热季节)降低用于储存LPG的LPG储罐中的温度和压力，因此能够容易地用LPG再充补LPG储罐。LPG充补系统被构造成利用汽油箱中的汽油温度低于LPG储罐中的LPG温度的事实而将一些汽油从汽油箱供应至LPG储罐，从而冷却LPG储罐的内部并且降低LPG的蒸汽压力，因此即使在外部温度很高的情况下(例如在炎热季节)也能够容易地用LPG再充补LPG储罐。
Abstract(English):

A liquefied petroleum gas (LPG) filling system of a bi-fuel vehicle is provided. The LPG filling system may be configured for reducing the temperature and pressure in an LPG bombe for storing LPG in the case in which the external temperature is very high, e.g. in the hot season, whereby it is possible to easily refill the LPG bombe with LPG. The LPG filling system is configured to cool the insideof an LPG bombe and to reduce the vapor pressure of LPG by supplying some gasoline from a gasoline tank into the LPG bombe using the fact that the temperature of gasoline in the gasoline tank is lowerthan the temperature of LPG in the LPG bombe, whereby it is possible to easily refill the LPG bombe with LPG even in the case in which the external temperature is very high, e.g. in the hot season.
