Title: Control method of sealed valve
Inventor: ICHIKAWA SO
IPC: F02M25/08
Filed: 2021-03-24
Abstract: To control a sealed valve so that a flow rate of flow-out purge air reaches a prescribed flow rate or less.SOLUTION: A second electromagnetic valve seat is set larger than a first electromagnetic valve seat in a diameter, a first electromagnetic valve is duty-ratio controlled, a second electromagnetic valve is on/off-controlled, and a flow rate of purge air is further finely controlled. After that, when pressure in a fuel tank is equal to or higher than a threshold, the first electromagnetic valve is duty-ratio controlled, and when the pressure in the fuel tank is lower than the threshold, control for combining the two electromagnetic valves is performed in response to the pressure in the fuel tank with the second electromagnetic valve as a second bench release position. Since the duty-ratio control of the first electromagnetic valve is performed so that a duty ratio becomes low as the pressure in the fuel tank is high, the flow rate of the purge air flowing out of the first electromagnetic valve seat can be prevented from exceeding a prescribed value, and the purge air of a quantity exceeding a processing capacity of a canister can be prevented from flowing out.SELECTED DRAWING: Figure 3
