The idea behind those changes is to get all of the ten fastest cars out on track during Q3.
Last year, some drivers elected not to go out to save sets of fresh tires for the race, and to start the race on the compounds they desired.
For 2014, Q1 will be reduced from 20 to 18 minutes while Q3 will be lengthened from 10 minutes to 12, to give drivers more time to complete two timed runs.
Drivers who choose not to go out on the track will start the race on the tire they used in Q2.
The tweaks need to be approved by the World Motor Sport Council of the FIA before being introduced in time for the season-opening Grand Prix of Australia, March 16.
