<p><P>PROBLEM TO BE SOLVED: To provide a device capable of performing correct distribution and having enhanced purge capacity by improving a device which has an electromagnetic canister purge valve and a control circuit to distribute and feed volatile components of fuel. <P>SOLUTION: The device to distribute and feed volatile components of fuel to, in particular, an intake pipe of an internal combustion engine of an automobile has one electromagnetic canister purge valve which is controlled by a proportional operation of the pulse width modulation system, and one control circuit, and performs adjustment to compensate disturbance from the outside on the current running in a coil of the canister purge valve by utilizing the control circuit. A device to detect at least one of (1) the mass flow and/or volume flow passing through the valve, (2) a space between a valve seat and a seal element of the valve, and (3) the ratio of hydrocarbon (CHx) in the volume flow is provided, and the current running in the coil can be adjusted according to at least one of the mass flow, the volume flow, the space between the valve seat and the seal element, and the ratio of hydrocarbon in the volume flow. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
