  • System and method to control fuel injector reactivation during deceleration fuel shut off
    Patent number: 7497805
    Abstract: A method of controlling fuel injection in an engine of a vehicle comprises reactivating fuel injectors based on release or decrease of driver braking during deceleration fuel shut off operation. According to another aspect, a method of controlling fuel injection in an engine of a vehicle comprises reactivating fuel injectors based on release or decrease of driver braking during deceleration fuel shut off; and increasing air flow to a cylinder before reactivation of fuel injectors in response to said release or decrease of driver braking to enhance torque response. The methods allow an engine to exit DFSO earlier by making use the brake input and effort, which provides time to reactivate the fuel injection and stabilize torque control prior to tip-in.
