Biodiesel Capable

Biodiesel capability up to B20: Designed to handle a mixture of up to 20% biodiesel by volume and 80% petroleum diesel fuel.
Biodiesel of ASTM D7467 Grade S15 (15 ppm sulfur maximum) should be used.

Cylinder Block

Upgraded aluminum cylinder heads with an inverse flow design: Air intake from the bottom and exhaust at the top.
Use of aluminum: Helps keep overall vehicle weight down.
Dual water jackets: For enhanced cooling and increased strength.
Six head bolts per cylinder: Improve sealing and maintain cylinder integrity.
Compacted graphite iron (CGI) deep-skirt engine block: Reduces weight while maintaining maximum strength.
Instant-start glow plugs: Provide quick starts even in extremely cold conditions.
Unique steel piston assembly: Designed for heavy-duty load-bearing capability.
Strong crankshaft and low-friction polymer-coated crankshaft main bearings: Enhance durability.

Fuel/Water Separator Trap

Large fuel/water separator trap: Increases time between drain intervals.
Water in fuel indicator: Notifies driver when to drain the separator.

Intake and Exhaust

Four-layer exhaust manifold gasket: Enhances durability.
Inboard exhaust design: Positions exhaust manifolds between the cylinder heads above the block.
Single turbocharger attachment: For faster air displacement and more power.
Improves throttle response and NVH (noise, vibration, and harshness) characteristics.

Turbocharger

Honeywell Commercial Truck Turbo: Tighter clearance with electronic actuator.
Large turbocharger: Accommodates high airflow for maximum power and enhanced high-altitude performance.
Compact and efficient variable-nozzle design: Delivers maximum power quickly.

Fuel Injection

High-pressure common-rail fuel injectors: Deliver up to five fuel injections per combustion cycle.
36,000-psi fuel injection system: With precise metering and spray control.
Fuel injector tips: Designed for precise fuel atomization, maximized combustion, low NVH, clean emissions, and reduced fuel deposits on valves.

Oil System

Optimized oil pan capacity: Provides up to 1-year/15,000-mile oil change intervals.
Intelligent Oil-Life Monitor.

Engine Power

6.7L Power Stroke V8 Turbo Diesel

475 horsepower @ 2,600 rpm
1,050 lb.-ft. of torque @ 1,600 rpm

Engine Technologies

Driver-Controlled Engine Exhaust Brake with Auto Setting

The engine exhaust brake is incorporated within the turbocharger on the available 6.7L Power Stroke V8 Turbo Diesel engine. It adjusts the vanes on the exhaust side of the turbocharger to generate engine exhaust back pressure or engine braking, providing greater vehicle speed and towing control, reducing brake fade and lining wear.

System Details:

Three Settings: On, Auto, and Off.
On Setting: Full engine braking is applied when the accelerator pedal is released, reducing vehicle speed.
Auto Setting: Modulates engine braking to maintain the intended vehicle speed based on accelerator and brake pedal use, eliminating "overbraking" and providing the correct amount of engine braking required.
Off Setting: The default mode each time the vehicle is started, accessible by pressing the engine brake button when in the Auto or On setting.

Smart Charging Alternator

A smart charging alternator controls charging system voltage during vehicle acceleration and deceleration, enhancing efficiency.

More Details:

Charging Process: Alternator provides charging via a pulley and belt operated by the engine, exerting mechanical load as current is required.
Efficiency Optimization: Decreases alternator output during acceleration and increases output during braking or deceleration.
Fuel Savings: Reduces additional engine accessory belt load, resulting in less fuel consumption.
System Communication: Works with the Aggressive Deceleration Fuel Shutoff (ADFSO) system to ensure the battery is adequately charged.

Stationary Elevated Idle Control (SEIC)

Acts as the “throttle kicker” when increased engine speed is needed, consisting of a strategy embedded in the powertrain control module (PCM) and a set of blunt-cut wires to command it.

System Details:

Engine Speeds: Ranges from 900 to 3,000 rpm for the 6.7L Power Stroke V8 Turbo Diesel engine.
Installation: Upfitters must complete the SEIC/PTO circuitry as detailed in the Body Builders Layout Book.
Components: Selling dealer needs to obtain a power takeoff (PTO) provision controller or switch from an aftermarket provider, with “Upfitter Switches” (66S) possibly having one switch dedicated for PTO usage.

Turbocharging Basics

Turbocharger Function: Uses the engine's exhaust gases to spin a turbine, driving a compressor to force more air into the engine, allowing smaller engines to generate the power of larger displacement engines.

Turbo Lag: The delay for the turbocharger to spin after the accelerator is pressed, caused by the wait for exhaust gas to spin the turbine and drive the compressor.

Power Stroke Benefit: Uses a large turbocharger for high airflow, producing substantial power and enhancing high-altitude performance. The design reduces cost, weight, complexity, and underhood heat while providing quick response times.
