FUEL INJECTION CONTROL DEVICE FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To improve poor restarting when fuel vapor is generated, in a fuel injection control device for an engine for starting the engine by human power without installing a battery. SOLUTION: This fuel injection control device for the engine includes: an injector supplying fuel to the engine based on pressure of fuel supplied by a fuel pump; a power generation means generating electricity based on rotation and driving of the crankshaft of the engine; a starter starting the engine by the human power; and a control means initiating a start by voltage generated by the power generation means and calculating the amount of fuel injected based on the operating condition of the engine. The control means is provided with: an injection quantity calculation functioning section for calculating injection quantity supplied to the engine according to the operating condition of the engine; an injection time conversion coefficient calculation functioning section for calculating an injection time conversion coefficient for converting into injector drive time from the injection quantity based on a predicted fuel pressure value; and an injector drive time calculation functioning section for calculating the drive time of the injector based on the output of the injection quantity calculation functioning section and the output of the injection time conversion coefficient calculation functioning section.
