ELECTRONIC CONTROL FUEL INJECTION DEVICE OF INTERNAL-COMBUSTION ENGINE

摘要

PURPOSE:To obtain better running even in high place by providing a mixing ratio correcting coefficient setting means setting a mixing ratio correcting coefficient in a running zone performing fuel increase correction and the running zone. CONSTITUTION: A basic injection amount setting means E setting a basic injection amount of fuel based on intake flow signal from a heat ray type flow meter C and engine rotation speed signal from an engine rotation speed detecting means D is provided. A mixing ratio correcting coefficient setting means I sets the value of mixing ratio correcting coefficient in a running zone performing fuel increase correction and the running zone based on a throttle valve opening signal from a throttle valve opening detecting means H and an engine rotation speed signal from the engine rotation speed detecting means D. Thus, running range performing fuel increase correction can be obtained even in high place and better running can be made.
