METHOD FOR OPTIMIZING THE OPERATION OF A MOTOR VEHICLE WHEN USING THE MOTOR BRAKE

摘要

The fuel flap valve (2) is controlled by an acceleration pedal (3). The pressure upstream and downstream of the valve is controlled so that the vacuum is always inferior to a threshold value of eight hundred millibars. The position of the acceleration pedal is measured so that the engine braking is initiated when the pressure on the pedal decreases.
