internal combustion engine fuel tank fuel vapor discharged from the system to prevent the adsorption filter (Adsorption filter for fuel vapor exhaust preventing system of fuel tank in internal combustion engine)

摘要

the tank drain valve to accommodate divergent in the adsorption filter is well known. however, this kind of stand is complicated, the manufacturing cost is high.;this invention is proposed in a fuel tank (4) to prevent the fuel vapor emission system (1), an adsorption filter (6) is one of the valve (20) with a valve (20,) is a valve (20) of the communicating pipe (21) of the can. at the ub0b4uc5f0 (22) and the suction pipe connection. and the adsorption filter (5) of the casing (8) of the tube (5) as soon as possible to the tank after the fuel tank (4) and the can. the valve (20) of the adsorption filter (6) of the casing (8) installed in a bend (37) can be inserted into the casing (8) to maintain. according to the invention of the adsorption filter is compressed, especially in the mixed flame ignition type fuel vapor emission system for prevention and control.
