  • Fuel-cut control system for automobiles with lock-up type automatic transmission
    Patent number: 5490815
    Abstract: A fuel-cut control system for an automobile is equipped with an engine with a fuel-cut device and an automatic transmission with a lock-up torque converter, and includes a step-by-step fuel-recover device which cooperates with the fuel-cut device and is responsive to transition from coasting to acceleration running, for recovering each of engine cylinders from fuel-cut step-by-step, while continuing a locked-up state of the torque converter in its lock-up range during the transit.
