Ford Power Stroke V8’s Advanced Combustion System Delivers Best-in-Class Horsepower, Torque and Fuel Economy

  • The tip to a 6.7-liter Power Stroke’s class-leading outlay and fuel economy is a rarely fit explosion system
  • Ford engineers used a companys tellurian diesel engine settlement imagination to rise a explosion complement in a 6.7-liter Power Stroke V8
  • 6.7-liter V8 delivers an industry-best 400 horsepower and 800 lb.-ft. of torque and best-in-class fuel economy

DEARBORN, Mich., Apr 12, 2011 More appetite and aloft fuel economy? Traditionally, we dont grasp both when we settlement a new engine.

But Ford powertrain engineers have been rewriting a book on engine settlement lately, augmenting appetite and fuel economy with any new engine.

A box in indicate is a new 6.7-liter Power Stroke diesel V8 offering in a F-Series Super Duty pickup.

When Ford Motor Company operative Joshua Styron, Ph.D., began work on a explosion complement of a new 6.7-liter Power Stroke engine, he believed that clever courtesy to a settlement of a pistons and accurate chain of a fuel injectors and feverishness plugs could outcome in an engine that delivered some-more power, aloft fuel economy and reduce emissions than a engine it was replacing.

He was right.

The 6.7-liter Power Stroke, a first-ever Ford-designed, Ford-engineered and Ford-built diesel heavy-duty pickup engine, is rated during 400 horsepower and 800 lb.-ft. of torque, adult from a prior Power Strokes 350 horsepower and 650 lb.-ft.

The new engine generates this class-leading appetite while delivering an considerable 20 percent fuel economy benefit over a predecessor, creation a Ford Super Duty best in category for fuel economy among heavy-duty pickups.

This week during a SAE World Congress, Styron presents a technical paper detailing how he and his group worked to rise and exam a super-efficient explosion complement pistons, fuel injectors and feverishness plugs for Fords award-winning new Power Stroke diesel V8.

At this year’s Congress, Ford engineers are presenting no fewer than 38 papers during a three-day conference, covering a operation of topics including engine design, fuel economy, safety, lighting and aerodynamics.

A special engine for a special truck

Because a Ford Super Duty is a work lorry designed to transport complicated loads, horsepower and torque had to be a tip priority for a new Power Stroke V8 diesel.

Styron pronounced a engineering brief for a 6.7-liter stressed performance. Four hundred horsepower was a target. Early in a growth program, fuel economy was noticed as many reduction critical to this patron than appetite and torque, Styron said. But we believed we could broach a good multiple of both — 400 horsepower along with fuel economy that was not usually significantly improved than a aged 6.4, though aloft than a competitors engines, too.

Making fuel economy a priority on a new Power Stroke was a right move. With oil offered for some-more than $100 per tub and diesel fuel during some-more than $4 a gallon in many tools of a country, Ford Super Duty business will save income any time they fill up.

The vigour on a Power Stroke engine settlement group was immense. The effusive 6.4-liter Power Stroke was impending a finish of a run in a Super Duty and Ford engineers knew improvements were on a approach from rival diesels in General Motors and Dodge trucks. Added to that, emissions mandate were tightening for a 2010 indication year. So, courtesy to fact around a explosion complement would be a pivotal to delivering a improved engine by any customary of measurement.

Experimenting with pistons, injectors and feverishness plugs
To broach class-leading fuel economy and excellence as good as reduce emissions, a explosion complement had to make a best use of a singular supply of uninformed atmosphere entering a engine, pronounced Styron. Combustion systems with a best atmosphere function remove a many feverishness from a fuel, furnish reduction slag and NOx, and minimize a appetite compulsory to siphon uninformed atmosphere into a engine.

Styron and his group used mechanism simulations to weigh piston play shapes, accurate chain of a fuel mist within a explosion chamber, feverishness block positioning and other factors. Following consultations with diesel engine experts during Ford’s Dunton Technical Center in Great Britain and a Ford Research Lab in Aachen, Germany, Styron’s group built dual single-cylinder antecedent engines. A extensive exam devise was grown to optimize any blueprint and finally select a one best performer.

The winning settlement facilities a chamfered re-entrant bowl, fine-tuned injector targeting and best atmosphere whirl that is matched to a super-efficient mist pattern.

This settlement provides a best blending of fuel and atmosphere in a complicated avocation lorry engine, pronounced Styron. When a initial using prototypes of a 6.7-liter Power Stroke were built, a explosion cover settlement was accurately a same as a one selected from a single-cylinder exam engine.

The explosion complement is unequivocally a heart of a engine. It determines a engines ability to use air, combined Styron. Get it wrong, and we finish adult with bad fuel economy and aloft emissions. The fact that we got a answer right saved us time and money. The finish outcome is that Ford Super Duty business now have a many absolute and fuel fit diesel pickup engine income can buy.
