PURPOSE: An injector control method and apparatus are provided to secure a desired fuel injection amount when the valve opening operation is interfered by viscous material or the like. CONSTITUTION: An injector control method is as follows. Tip control is performed by valve opening current for opening a valve from a closed state. Injector control mixed with PWM control is performed by valve opening holding current for keeping the valve opened. If it is determined an injector control device requires the increase of valve intake force based on the predetermined data which the injector control device detects, the part under the PWM control is also converted to tip control. |
