Abstract
A system for preventing loss of fuel due to evaporation in internal combustion engine, particularly in automotive engine. The system has a casing accommodating a fuel gas absorbent. A separator chamber adapted to separate the liquid phase and gaseous phase of the fuel from each other is disposed in a passage through which a tank port leading from a fuel tank is communicated with the absorbent. The passage is so constructed as to permit only the gaseous phase of the fuel to be sent to the absorbent.
