When a new Ford Power Stroke diesel comes along in 2007 to replace the current 6.0-liter model, it may represent the first use of piezo injectors in a pickup truck. The Siemens-built injectors should help International's 6.4-liter twin-turbo meet upcoming emission standards while also improving upon its predecessor's spotty reliability record, as well as giving the Blue Oval oil burner an European-like level of technological sophistication.

The injectors work via the piezoelectric effect, as the name might hint. They use a small disc of quartz-like crystalline material that deforms when subjected to a high-voltage low-current source, which provides the injector opening and closing action. With cycle times as low as 0.2 milliseconds, such injectors are several times faster than conventional solenoids, which in turn is said to allow up to seven injector events during each compression stroke. The precision of each injector is also increased, with injector-to-injector variation of only a few percent.

All of this adds up to a significant improvement in emissions and fuel economy, but at a price; piezo injectors are reportedly up to twice as expensive as the traditional solenoid-based squirters. With the average pickup truck diesel engine carrying a $5,000 premium, we're guessing that there's plenty of room in the budget.

      #1 you're an idiot and a moron ... autoblog doesnt mean its for cars only .. where did you ever get that idea? Auto as in automobile as in cars and trucks ... if u want to create just for cars then make carblog ..moron!

      What about the transmission? A 3 speed + overdrive making 6 forward ratios (OD on the 2nd of the 3 speed, is ~1.13, used for cold starts to warm up the tranmission fluid quicker)
      still gets beat by the Alison 1000 (with extra OD gear) 5.1 : 4.4 in ratio coverage, and smoothness.
      And if you have to back up a 10,000+ lb trailer, the reverse of the Allison is 4.49, compared to 2.88 of the Torque Shift.

      Fact #1: Trucks are automobiles.
      Fact #2: The title of this site is "Autoblog", not "Carblog" or "We-don't-like-trucksblog".
      Fact #3: Trucks and SUVs make up slightly more than half of the US automotive market.
      Fact #4: Very few passenger cars outsell the diesel-equipped Super Duty, which itself constitutes slightly more than 0.5% of all vehicles sold in the US.
      Fact #5: The technology discussed above is not limited to trucks, and will produce roughly the same positive and negative attributes when applied to passenger cars.

      I'm still not quite understanding why the Comments section of this post turned into a debate on the virtue of trucks and their place on this blog instead of constructive discussion on the pros and cons of piezo diesel injectors, but I guess that the first comment of any post tends to establish the tone and mood of the rest. 'Quack, I'm a bit disappointed.

      why cant we look at this as a move toward technical advancement in the auto industry as a whole? Anything artcle that discusses more efficient diesels, considering the amount of them on the road worldwide, is something I am interested in.

      I agree with the concept of diversity of information. If you aren't interested in an article, skip it! Also, I wonder if it wouldn't make sense to keep the responses directed towards the subject of motor vehicles rather than personal attacks...just a thought?

      Since "you're" so good at English grammar why don't you do us all a favor and leave the cars/trucks (also known as "auto's" hence the name "auto"blog[another one of those tricky English words referring to cars and trucks indiscriminately]) to the men and start "your" own gay poetry blog.

      PJ, your idea seems like a good one, 'till you realize that Autoblog Green did nothing to keep the posters like #1 off these boards.

      This is a site for AUTOMOTIVE NEWS. A truck is still an automobile. It is NOT a "car", but it is Auto-related.

      I said what I said about trucks because unless they're doing something useful, they're annoying.

      Many of the trucks I see driving around are empty and often jacked up so high that nothing could be conveniently loaded into them.

      Truck drivers are probably no better or worse than car drivers, but when trucks smash into smaller vehicles they do more damage and are a danger to the rest of us.

      With respect to that lower primate, Steve M., why does he make comments about a "gay poetry blog" unless he's sucking the kinds of things that make him question his own sexuality?

      Piezo... OK, what type of piezo injectors?

      HEUI?

      Pumpe-Duese? (Unlikely, but more reliable than HEUI. VW's going to Piezo-Pumpe-Duese)

      Common rail? (It would be nice if it was CR...)

      If you don't want to read the story, scroll past it. Nobody's forcing to you read it, or even comment on it.

      I'm a car enthusiast, and don't mind reading about trucks. I can only fantasize about owning a Ferrari so many times in a day. Every once in a while, the real world sets in and I would like to read about cars that are more down-to-earth.

      To those of us who could actually use the utility of a pickup truck on a regular basis (hauling wood pellets, dirt, loam, gravel, an ATV, lumber, shingles, towing a sports car/sailboat/etc, offroad exploring, plowing snow, etc.) these stories are interesting.

      #2 - No, he's not. A fair share of the enthusiast community couldn't care less about the latest $50,000 V-10 dualies now appearing at a Starbucks near you.

      I do think that those interested primarily in the engineering aspect of automobiles might want to see this particular story, though.

      Truckblog doesn't sound like a bad idea to me--I'd glance at it from time to time myself. Too often truck stories here on Autoblog generate mindless "trucks are good/bad" shouting matches in the Comments, especially since truck fans seem to be even more fanatically loyal to individual brands (and countries of origin) than car enthusiasts.

      I'm sure there are many people who use these trucks for their intended purpose. With a separate blog, they could hash out their differences on their own terms (and take the poser truckers with them, away from Autoblog).
