Title: Fuel tank internal pressure adjusting device
Inventor: NISHIMURA YUSAKU
IPC: B60K6/445
Filed: 2012-06-01
Abstract: PROBLEM TO BE SOLVED: To make pressure in the inside of a fuel tank negative and to reliably keep the negative pressure state in the fuel tank while an internal combustion engine is stopped in an evaporated fuel processing system having a seal valve in an evaporated fuel passage for connecting a canister to the fuel tank.SOLUTION: When an internal combustion engine is stopped, an atmospheric opening and closing valve is closed (S124), a seal valve is opened (S126), and the pressure in a fuel tank is made negative by driving a negative pressure pump (S128). After making the pressure negative, and before executing the opening of the atmospheric opening and closing valve (S134) and the stop of the negative pressure pump (S136), the seal valve is closed (S130) and the tank internal pressure Ptf is kept. Thus, the tank internal pressure Ptf is kept negative, while the atmospheric opening and closing valve is opened (S134) to return the pressure in the canister to the atmospheric pressure. Accordingly, the pressure in the fuel tank can be negative while the internal combustion engine is stopped, and the negative pressure state in the fuel tank can be reliably kept.
