Gas saving hydraulic assisted brakes
New braking technology using hydraulic fluid control from braking to continue rotating engine with fuel (gas) supply cut off at key moments during braking. First the standard brake discs are reduced in size and are backed-up by small rotary hydraulic pumps (RHP) that are computer controlled. When the brake is applied the initial braking is done only by the RHP\'s. The computer controls the RHP\'s valve based on brake pedal pressure. Under excessive braking the standard mechanical disc brakes add extra stopping force. Basically under light braking only hydraulics would stop the car. When braking the RHP\'s pump fluid to a hydraulic motor mounted on the engine block and engaged with the flywheel. The engine fuel is cut and the rotation of the engine is used for breaking which saves fuel and cools engine. When the RPM\'s drop to factory settings the fuel supply is restored and the engine idles under it\'s own power. Basically no fuel is used during the entire braking process and with good consistent braking habits a person could save the most gas.

No need to add a complicated hydraulic system when you can simply shift to lower gears automatically to aid braking.

Gary L Cool Steven i didn't realize Ford was doing part of my idea. I have had the idea for over ten years, but never saw anyone else doing the total shutoff. My design also uses braking energy from rotary hydrualic pumps and a small hydrualic motor on the engine to keep the engine rotating at idle speed so all accessories continue to function. I have also submitted my compressed air version which has NOT been posted yet. That version uses compressed air (CA) instead of hydrualic fluid to rotate the engine. The advantage it gives is that compress air can be stored and used to continue to rotate the engine during a stop increasing fuel economy. The CA can be stored in tank that are creatively built into the front frame members and front cross beam. I figure at least three high pressure tanks could be built as "part" of the box frame. They would just be cylinders in shape. This CA can easily rotate the engine for wuite some time and even add a boost to acceleration. See my new submission when posted. It referances Tata Motor of India's CA motor car development that was on 60 minutes.

Steven C Is this a different technology then what Ford is already using?Aggressive Deceleration Fuel Shut-Off We are also deploying Aggressive Deceleration Fuel Shut-Off (ADFSO) technology to improve fuel efficiency. ADFSO allows fuel supply to the engine to be shut off during vehicle deceleration and then automatically restarted when needed for acceleration or when the vehicle's speed approaches zero. This new system builds on the Deceleration Fuel Shut-Off technology available in our existing vehicles by extending the fuel shut-off feature to lower speeds and more types of common driving conditions, without compromising driving performance or non-CO2 emissions reductions. This improved fuel shut-off will increase fuel economy by an average of one percent. An additional benefit of the ADFSO technology is increased deceleration rates, which should extend brake life and improve speed control on undulating roads. This technology was implemented in mid-2008 on the new Ford Flex and the Lincoln MKS and in late 2008 on the 2009 model year Ford F-150, Ford Expedition and Lincoln Navigator regular and extra-long models, as well as the Ford Escape and Mercury Mariner. In the next two to three years we plan to implement this technology on as many vehicles as possible, beginning with front-wheel-drive, six-speed-transmission vehicles.
