Interrupt injection control device for electronical controlled gasoline injection type internal combustion engine

Abstract

PURPOSE: To enable interrupt injection corresponding to the quantity required by an engine and to improve acceleration ability by conducting interrupt injection at the time of a designated crank angle in the intake stroke according to the latest throttle valve opening change rate at that time in the respective cylinders. CONSTITUTION: In a system where a fuel injection valve D is controlled through output means C according to the fuel injection quantity set by fuel injection quantity setting means B according to an output of engine operating condition detecting means A, there are provided change rate detecting means E for detecting an opening change rate of a throttle valve to the open side at every designated small time and intake stroke cylinder detecting means F for detecting a designated crank angle in the intake stroke of each cylinder. On detecting a designated crank angle in the intake stroke of a specified cylinder, an interrupt injection quantity for the specified cylinder is set in interrupt injection quantity setting means G according to the latest throttle valve opening change rate. An interrupt injection signal corresponding to the set interrupt injection quantity is output from output means M. COPYRIGHT: (C)1988,JPO&Japio
