Abstract
PURPOSE: To prevent an ignition failure and reduce torque fluctuations by reading out a correction coefficient previously memorized in a memory storage for correcting the injection amount of fuel that has been worked out by a computation circuit, and returning as increasing and decreasing the injection amount of fuel at the time of returning after a fuel cut.
CONSTITUTION: A fuel injection controller is provided with a computation circuit 10 into which outputs of a sucked air amount sensor 3, a throttle opening degree sensor 4, a water temperature sensor 5, and a revolution sensor 6, are inputted for working out the injection amount of fuel, and a fuel cut circuit 11 into which outputs of the above written sensors 4W6 and a car-speed sensor 7 are inputted to command a fuel cut and its releasing time. In this case, a counter 12 and a memory storage 13 are newly provided. In this construction, after a command signal for releasing fuel cut is generated, a correction coefficient memorized in the memory storage 13 corresponding to the counted value in the counter 12 is read out and inputted into the computation circuit 10 for correcting the injection amount of fuel at the time of returning.
