2011 Ford Super Duty

September 25th, 2009 by Arman

One of the best-selling full-size trucks in America is indeed the Ford Super Duty. Its gigantic size and stunning statics definitely fits in the Yanks culture very well! Now this mighty fella will be having a new model for next year which will be presented as a 2011 model.

The new Super Duty will get two new diesel and gasoline engines. First there is the .7-liter Power Stroke V-8 turbocharged diesel engine which can be fed by up to 20 percent biodiesel and 80 percent petroleum diesel, and then a 6.2-liter V-8 gasoline which has two spark-plugs per cylinder.

Benefits of the new 6.7-liter Power Stroke diesel engine:

First use of a compacted graphite iron (CGI) engine block in a Super Duty-class vehicle in North America; CGI is stronger than cast iron, and Ford successfully has used the material in engine blocks in products around the world. The block structure was optimized for reduced weight and maximum strength to meet the demands of higher torque and more horsepower and enable class-leading fuel economy.
Unique inboard exhaust and outboard intake architecture, an automotive-industry first for a modern production diesel, reduces overall exhaust system volume, which leads to better throttle response; a reduced exhaust system surface area minimizes heat transfer to the engine compartment and improves NVH (noise, vibration and harshness).
The turbocharger features an industry-first dual-sided compressor wheel that works in a single housing. The unit is uniquely center-mounted on a pedestal low in the back of the valley for improved NVH. The design allows the single unit to deliver the advantages of a twin-turbocharger system in a smaller, more efficient package, combining the benefits of a small turbocharger (faster response) and a large turbocharger (ability to compress and force more air into the engine for more power) in one unit.
The high-pressure fuel system injects fuel at more than 29,000 psi. The system delivers up to five injection events per cylinder per cycle using eight-hole piezo injectors to spray fuel into the piston bowl. The direct-injection system is calibrated and phased for optimum power, fuel efficiency and NVH.
Aluminum cylinder heads for reduced weight; the mid-deck construction with dual water jackets provides increased strength and optimal cooling; six-head bolts, instead of four as found on other engines, help improve sealing and maintain cylinder integrity even with the higher firing pressures.
Compatible up to B20 fuel, allowing greener fueling options of up to 20 percent biodiesel and 80 percent petroleum diesel.

Benefits of the new 6.2-liter V-8 gasoline engine include:

SOHC valvetrain with roller-rocker shafts: The single overhead camshaft (SOHC) per cylinder head design results in a stiff valvetrain that allows optimized camshaft lift profiles and results in great low-speed torque. The roller-rocker shafts allow valve angles to be splayed, resulting in optimized intake and exhaust port layout for better breathing.
Dual-equal variable cam timing: Intake and exhaust valve opening and closing events are phased at the same time to optimize fuel economy and performance throughout the engine speed range and throttle positions.
Two spark plugs per cylinder: Due to the large bore size, two spark plugs per cylinder are used to more efficiently burn the fuel-air mixture in the combustion chamber, enabling better fuel economy and increased engine torque. The twin plugs also help the engine maintain a smooth, stable idle.
Dual knock sensors: A knock sensor on each bank of cylinders of the V-8 engine allows the spark timing of each of the cylinders to be individually optimized real time, throughout the engine speed range. The engine learns the optimum timing via an adaptive algorithm.
Better engine crankcase “breathing” and efficiency: Significant development work and computer-aided engineering optimized the cylinder block for more efficient airflow in the crankcase as the pistons move up and down in the bores, resulting in improved torque at higher engine speeds. Piston-cooling jets squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions. The cooling jets also allow for a higher compression ratio for better engine efficiency and faster engine oil warm-up on cold starts, also improving fuel economy.

Both engines are mated to the all-new 6R140 heavy-duty TorqShift six-speed automatic transmission and comes with a range of electronic and mechanical features to help the car holding to its “Best In Class” towing and payload title. Some of these features include: Live Drive PTO (Power Take Off), Ford’s lauded Trailer Sway Control (TSC), AdvanceTrac with Roll Stability Control, integrated trailer brake controller with ABS and…

Other enhanced towing, off-road control features and safety improvements include:

Hill Start Assist, which applies brakes to prevent rollback
Hill Descent Control™, which uses the accelerator and brake to set, and then hold, the speed
Electronic Locking Differential, which provides maximum traction by forcing the rear wheels to turn at the same speed
Standard tire pressure monitoring system on all SRW (single rear wheel) models
Optional side air bags and air curtains
A new available 4.2-inch LCD screen includes information on specific features such as Trailer Brake Control and Tow Haul
