ABSTRACT:
An engine is coupled to an automatic power transmission having a lockup device. The lockup device is in an operative position when the speed of the engine is higher than a preset lockup reference level, and is in a rest position when the engine speed is not higher than the lockup reference level. A deceleration sensor detects when the engine is required to decelerate. A speed sensor detects the speed of the engine. A fuel-control device is associated with the deceleration sensor and the speed sensor to supply fuel to the engine when the engine is required to decelerate and the engine speed is lower than an adjustable fuel-supply control level. The fuel-control device also serves to interrupt the supply of fuel to the engine when the engine is required to decelerate and the engine speed is not lower than the fuel-supply control level. When the lockup device is in the rest position, the fuel-supply control level is equal to a first preset value. When the lockup device is in the operative position, the fuel-supply control level is equal to a second preset value greater than both of the first value and the lockup reference level.
