CONTROLLER FOR THROTTLE VALVE OF ENGINE

摘要

PURPOSE:To design improvement of deceleration performance by stopping fuel supply and correcting a throttle valve to fuel opening or high opening close to the fuel opening when an engine is decelerated. CONSTITUTION:State of decelerating operation of an engine is detected by a detecting means 52 for state of decelerating operation. Fuel supply is stopped by a fuel stopping means 53 in the state of decelerating operation of an engine. A high speed signal of an engine speed detecting means 27 and the signal of the above fuel stopping means 53 are input to a correcting means 55, and a throttle valve opening is corrected to high opening close to full opening when fuel supply is stopped and the engine speed is high. Deceleration performance is improved by this mechanism.
