Abstract
A valve controller includes a detector detecting a shutdown command signal to shutdown an engine, a driving circuit for driving a motor, and a power source controller. The power source controller turns on the driving circuit until the predetermined period has passed since the shutdown command signal is detected. Thus, the valve controller adjusts the valve opening/closing character in such a manner as to be suitable to an engine condition.
