Duramax Diesel Engine Production Halted for the Rest of 2021

It's been a rough year for automakers, but especially for GM. Semiconductor shortages have hit all of the Big 3 automakers, causing production disruptions. GM seems to had more than its share of woes. 

In August we wrote about how strong the demand has been for diesel trucks, though at the end of this article we referenced a temporary halt to production that was announced. That ominous warning evolved quickly to a more serious concern, as GM was forced to change its tune. The temporary parts shortage will impact the engine more than initially expected. The temporary parts shortage would have a bigger impact on the engine than initially expected.

Last week news broke that production had been halted for the rest of the year on its 3.0L LM2 GM Duramax diesel engine. The article does not explain where the derailment took place. Rather it takes advantage of the bad news to remind us of its features and applications.

The LM2 Duramax diesel is assembled in Flint, Michigan. It has been one of the options for their full-size half-ton pickups and full-size SUVs. These would include the Chevy Silverado 1500, GMC Sierra 1500, Chevy Tahoe, Chevy Suburban, GMC Yukon and Cadillac Escalade.

If you ever attend the SEMA Show in Las Vegas, you'll find that GM is not only proud of its cars but also of its engines. The engines are set on pedestals in the massive booth  that historically sprawls in the center of the main hall. They're impressive.

According to the story in GM Authority, "The LM2 engine features a straight six configuration with a DOHC valvetrain, 84mm bore, and 90mm stroke, with a 15.0:1 compression ratio. The block and heads are made of aluminum, with a forged steel crankshaft and forged rods. The pistons are made from hypereutectic cast aluminum alloy, while the cylinder liners are made from iron."

The halting of Duramax diesel engine production wasn't GM's first black eye this year. In July GM announced a recall for 410,019 trucks due to faulty roof rail airbags. The problem was related to moisture issues that might cause the inflator end cap to detach from the inflator, or cause the inflator to rupture. The 2015-2016 Chevy Silverado 1500 and Chevy Silverado HD, as well as the 2015-2016 GMC Sierra 1500 and GMC Sierra HD were the model years impacted. 

All this safety equipment can be a blessing when you need it. For manufacturers dependent on suppliers, it's just one more thing that can go wrong. In addition to an army of laborers, they are required to have a battalion of lawyers as well.

You will find the full story here.

Enjoy the holiday. We'll be back tomorrow.

XDP Launches Remanufactured Fuel Injectors for Ford 7.3L and 6.0L Diesel Engines

Xtreme Diesel Performance (XDP) has recently launched remanufactured fuel injectors for Ford 7.3L and 6.0L diesel engines. Each injector is precision remanufactured to ensure it exceeds the engine manufacturers’ most current design specifications, resulting in less than o.2 percent warranty rate. 

Each injector features improved end cap assemblies to help fix cold start issues. The nozzle flow testing process gives the injector a like-new performance. 

In the auto aftermarket the term "remanufactured" refers to parts that have been completely remanufactured to the standard of being like new. For those sensitive to environmental concerns, it's useful to know that remanufactured parts use 80% less energy than manufacturing parts from scratch. The process also conserves raw materials. 

XDP fuel injectors include all new connectors, O-rings, internal hardware, and springs, with the intensifier body and plunger matched to eliminate fuel dilution. A precision matched control valve and spool help to minimize oil leakage and maximize power output. 

XDP replacement fuel injectors are designed for…

• • 1997 FORD 7.3L POWERSTROKE (CALIFORNIA MODELS)
• • 1999 FORD 7.3L POWERSTROKE (EARLY MODELS)
• • 1999.5-2003 FORD 7.3L POWERSTROKE
• • 1999.5-2003 FORD 7.3L POWERSTROKE (#8 LONG LEAD)
• • 1994-1997 FORD 7.3L POWERSTROKE
• • 2004.5-2007 FORD 6.0L POWERSTROKE
• • 2003-2004 FORD 6.0L POWERSTROKE

Fuel injectors are small electrical components that are used to deliver fuel via a spray directly into the intake manifold in front of the intake valve in a diesel engine. 

Diesel fuel injectors are quite complicated. The injector has a high micron filter on the top inlet side which corresponds to small hypodermic sized holes on the bottom for the atomizing of the diesel fuel. 

The diesel fuel acts as a lubricating source for the injector’s internal parts. The main source of failure for injectors is water in the fuel. When water in the fuel displaces the lubricating properties the internal parts wear down and can quickly fail.

Injectors are an extremely important engine component. The injector valve opens and closes at the same rpm as the diesel engine. Typical RPM for diesel engines in North America is around 1800. This equates to roughly 140,000 times per hour! In addition to water in the fuel, injectors are subjected to carbon and dirt particles introduced into the unit via a bad air cleaner element. 

The type of fuel, grade and additives used also has a significant impact on the life expectancy of the fuel injector. The Engine Control Module (ECM) controls the fuel injectors in most electrical diesel engines. The diesel injectors constantly have power when the key is turned on regardless if the engine is turned over. 

The ECM grounds the injector, completing the circuit and causing the injector nozzle to open. The ECM after receiving information from various control sensors determines the length of time the injectors need to be grounded to inject the exact amount of fuel given the horsepower output demand from the engine.

The process of diesel injectors opening, closing, and dispensing the correct amount of fuel happens in milliseconds. Injector cycle firing is on average completed in 1.5 to 5 milliseconds. 

Diesel fuel injectors come in different shapes and sizes depending on the engine make and model as well as power demand. Automotive injectors are quite a bit smaller than heavy-duty diesel applications and are measured in cubic inches. 

There are two types of diesel fuel injectors: the first is called throttle body injection where 1-2 injectors are in the throttle body itself in the diesel engine and supply a metered amount of mist fuel spray into the intake manifold.  The second delivery system, known as individual port type fuel injector, is newer and more fuel efficient.

Readiness and Resilience: Diesel is the Gold Standard

Photo by Gene Gallin on Unsplash

Wildfires. Hurricanes. Flooding. Drought. Tornados. Extreme heat. How ready are you when emergencies come your way? Does your family, including your kids, know what to do?

September is National Preparedness Month (NPM), a time to raise awareness regarding the importance of being prepared for disasters and emergencies that can interrupt our lives at any time. The theme this year is "Prepare to Protect. Preparing for disasters is protecting everyone you love."

Yes, but what does this have to do with diesel? That is what Readiness and Resilience: Preparing for the Next Disaster is all about.

The story, published last week in the Diesel Technology Forum, begins like this:

Diesel is the gold standard for working in difficult conditions, when the most power is needed that can go deep into backcountry and work for hours, being highly mobile and untethered. Diesel’s hidden asset is the supportive and available global network of engine and equipment dealers, mobile and fixed fueling options, servicing, rental and parts networks.

From here the article details various aspects of preparedness, outlining the myriad types of disasters that have occurred and showing how diesel powered equipment has played an important role in helping us address these issues.

Some disasters are weather-related. The heavy floods in Tennessee and Europe are examples. The devastation wrought by wildfires out West have been brought on by drought. Other disasters, such as the Covid-19 pandemic, have made all of us feel uneasy and vulnerable.

The article cites the collapse of Champlain Towers in Surfside Florida as well. Though not really weather related, it no doubt has made some people lose sleep regarding the safety of their own condos and townhouses. 

The upside to all these news stories is that they can nudge us into action to think about, plan and prepares for our own readiness should the unexpected occur. Do you have an evacuation plan for emergencies? This is what National Preparedness Month seeks to instill in us, to get us thinking about our own preparedness. 

One aspect of preparedness, the article goes on to say, "is having the right tools and technology that you can count on." This, naturally, leads into the real point the DTF wants to get across. 

In these kinds of crises we turn to first responders -- those who get the first calls for rescues and getting folks out of critical situations -- jump into action and rush to the scene with trucks, gear and equipment. Their aim is to minimize loss of life and property. They also focus on keeping the power grid intact as well a transportation byways open. 

Utilities are a central concern for the response network. Having the equipment ready and personnel -- there are national networks for bringing in personnel -- all contribute to dramatically reducing response times recovery and restoration.

The article outlines the specialized heavy equipment for dealing with fallen power lines or cell towers. Other specialized equipment is used to lift and removed downed trees, drill holes to reset 120-foot poles, replace transformers and more. Sometimes refrigeration and cooling equipment is required. It all adds up to an impressive arsenal.

Coastal cities are dealing with increased flooding, like that taking place in New Jersey and New York right now in the aftermath of Hurricane Ida. Pumping stations and towable mobile dewatering pumps are part of the readiness inventory, along with backup generators, skid steer loaders and other material handling equipment.

Building collapses, too, require heavy equipment to clean up debris. The initial response team uses specialized equipment and techniques to find and rescue survivors in such tragedies.

Wildfires have their own mix of equipment needs from bulldozers and planes to pumper trucks, water tankers, and all-terrain field fire response vehicles. Those bulldozers may not be fast but they are powerful, and have a remarkable ability to maneuver through challenging terrain. They are a critical part of wildlife response effort. They boldly work to clear fire breaks, often at the fire's edge.

In all these readiness and response activities, diesel power plays a significant role. When dealing with emergencies of such a magnitude, having the right equipment is a must. In most cases it's diesel powered equipment because it's reliable, versatile, available and proven. Diesel power is a central part of being prepared.

The article ends by reminding us that Diesel plays an important role in our world today. You can read the original account here.

Toyota Land Cruiser with Diesel Power Goes Retro for 70th Birthday

“No worries, mate. It’s a diesel”

Need an excuse for a party? Toyota fans in Australia are celebrating the 70th birthday of the Land Cruiser. To mark the occasion, Toyota has released a limited-edition version of its 70-Series model. The interior has embellishments, but the style is definitely retro. It's being called the 70th Anniversary truck.

The story by Ronan Glon appeared early this month on the Autoblog.

Toyota is making only 600 units for this occasion with three options for its basic foundation: single cab, double cab or wagon. The color options are fun: French Vanilla, Merlot Red, or Sandy Taupe. The article runs through the various talking points regarding exterior styling before opening the door for a look inside the cabin. 

The 70-Series incorporates a number of first time embellishments, which you can also read about in the article. What interested us most was what's under the hood. As it turns out, the power plant is a 4.5-liter turbodiesel V8 with a 202 horsepower rating and 317 pound-feet of torque. There's no automatic on this truck, only a five-speed manual transmission. "Every commemorative Land Cruiser will offer users a snorkel, low-range gearing, locking front and rear differentials, plus a 7,700-pound towing capacity," Glon writes. 

For those unfamiliar, the snorkel enables an engine to breathe while underwater. During World War Two, jeeps were equipped with ten or fifteen foot breather extensions that enabled them to drive underwater while making a beachhead. (Here are some tips for installing a snorkel on your off-roading machine.)

Toyota has decided to make 320 double-cabs, 200 single-cabs and 80 wagons, only for Australia. We've heard no rumors about anything similar for the U.S. market. In fact, according to the Autoblog story, the next-gen 300-Series will not be sold in the U.S. either. On a positive note, Toyota did announce that it plans to re-release a selection of hard-to-find parts for the 40-Series Land Cruiser (FJ40) which was built from 1960 to 1984.

The last part of the article contained a lot of trivia that you may not have been aware of. Did you know....

--The Land Cruiser name plate appeared on a Studebaker decades before Toyota used it.

--The Toyota Land Cruiser is not actually turning 70 this year. Rather, this is the 70th anniversary of the BJ, a Jeep-like 4x4 used by the Japanese armed forces.

--The BJ became the BJT, a touring car sold in select markets. No more than 300 were built.

--The name Land Cruiser was first used by Toyota is 1954.

--Land Cruiser sales began in 1958, the year after Toyota opened an American division.

--Only one Land Cruiser was sold that year. It is now in a museum in Salt Lake City.

Car & Driver Puts 2021 Chevy Suburban Diesel to the Test but You May Have to Wait to Get One

A week ago Car & Driver published an enticing review of the 2021 Chevrolet Suburban. The story, titled Tested: 2021 Chevrolet Suburban Diesel Should Be the Default Choice, gave a mouth-watering review of the 2021 Suburban, went so far as to suggest that all Suburbans should be powered by the diesel Duramax 3.0 engine. 

Automotive journalist Ezra Dyer describes how "the 3.0-liter six is perfectly adapted to Suburban duty. Its 460 pound-feet of torque arrive at only 1500 rpm, imbuing the 6272-pound behemoth with an air of nonchalant muscularity in real-world driving."

The diesel Suburban is not a race car, and you wouldn't expect it to be with a 277-hp engine, but it does jump from zero to sixty in a quick 8.4 seconds, and adequate pace for merging into traffic.

For Dyer, one of the high points on this SUV is its stability. It's smooth. "With that luxurious 134-inch wheelbase and four-wheel independent suspension, the Suburban glides imperiously down interstates, whether perched on its base steel springs or the optional air suspension with magnetic ride control," he writes of the full-sized SUV. 

The noise volume on this car -- or lack of it -- is noteworthy. When cruising along at 70 mph, the volume is equivalent to a Lexus ES350. And of the noise you do hear, most of it is wind and tires, with only a mild hum coming from the straight-six on the other side of the firewall.

When it came to the low points of this story, there really wasn't much to say. The Suburban gets decent numbers when it comes to city and highway driving. And the diesel can tow around four tons if need be. Other "low points" read like high points, with the only real gripe being that the diesel Duramax is not the default engine and you have to request it. 

You can read the full story here. There are lots of photos.

And now the bad news. If you are one of those who was sufficiently enticed into considering this as your next purchase, hold your horses. The Fast Lane Truck (TFLTruck.com) just broke the news that GM is temporarily stopping production of the 3.0 Duramax Diesel Inline-6 engine due to a parts shortage.

These Covid-era supply shortages are more than annoying. Chip shortages have caused the automakers plenty of headaches already this year. Over the weekend GM confirmed that this will impact the Chevy Silverado 1500, GMC Sierra 1500, Chevy Tahoe, Chevy Suburban, GMC Yukon and Cadillac Escalade.

Fortunately it's only a temporary setback. They promise to resume production as soon as possible.   

A Tribute to Diesel Farm Trucks and Their Kin

Photo by Matt Palmer on Unsplash

Here's an interesting article about Farm Trucks that was originally published in the Idaho edition of Ag Proud. The article by Allen Schaeffer, Executive Director of the Diesel Technology Forum is packed with information about this very specific application of diesel technology. The DTF is a not-for-profit organization dedicated to raising awareness about the importance of diesel engines, fuel and technology. The article is titled simply "What is a farm truck?"

Now you'd think everyone would know this, but when you read a little further you'll see that nothing is really as simple as it seems, especially when you get into legal matters and governmental explanations. 

Wikipedia describes a farm truck as "a vehicle designated for agricultural use, and may include anything from small pickup truck or even vehicles fashioned out of old parts, to class 8 eighteen-wheeler trucks."

Mr. Schaeffer's definition is more detailed: "According to the U.S. DOT Federal Motor Carrier Safety Administration (FMCSA)a farm vehicle is one that is: registered in a state with a license plate that identifies it as a farm vehicle … transporting agricultural products, livestock, farm machinery or supplies to or from a farm, and is not used in for-hire motor carrier operations."

The next sentence amplifies the initial definition. "Some states in the United States have a special registration for farm trucks that includes restrictions such as distance the vehicle may travel from the farm." This is where it gets complicated because some states have restrictions that others do not. There are also licensing issues. That is, certain vehicles require a Commercial Drivers License (CDL) in some situations and in others you do not.

In 1900, when the nation was 60 per cent rural, trucks didn't exist yet. Horses did all the grunt work of bringing produce to market. Today, all the horsepower come from under the hood. 

"The most iconic farm truck of course is the pickup truck: half-ton, full-size, extended bed, crew cab, dually, fifth wheel – the list of options and configurations is near endless," he writes. And for the past few decades the Ford F-150 has been the leader of the pack.

Just how much of a leader Ford has been was revealed in a Great American Truck Survey involved 2000 truck owners. Here are some facts that you'll enjoy if you are a loyal Ford fan.

--More than 3,000 TV shows mention Ford trucks.
--Over 180 songs also mention Ford trucks.
--79% said they would give up alcohol for an entire year rather than give up their truck.
--15% have tattoos that reference a truck or their favorite brand.

Farm trucks usually arrive on the farm after undergoing wear and tear by a previous owner or two. Because these vehicles are used seasonally, they often don't accumulate as many miles as daily drivers. Schaeffer spends time explaining that despite limited season use farm trucks still require maintenance. Brakes, filters, fuel systems all need attention. The importance of fuel stabilizers and cold-weather additives can't be ignored either.

The article goes into detail regarding the tendency to overload trailers and truck beds when bringing in the sheaves, or whatever else you're harvesting. Be careful. Old equipment can suffer in those situations. A groaning engine is one thing, breaking a belt is much bigger issue. Having a tire go flat while carrying a heavy load across the middle of nowhere is something you just don't want to do. In fact, the author experienced that situation himself once. It wouldn't surprise me to learn that he's been warning farmers ever since, as he did here.

Diesel enthusiasts, he notes, received some uplifting news entering the 2021 season. It is the first year that all of the big three manufacturers offered a diesel engine option on all full-size pickup trucks. Pickups are today's workhorses for farmers, no question about it.

His closing statement shows how much the author is a real truck guy. "The FT/farm truck designation has real meaning – both to those behind the wheel and those in the motor vehicle enforcement world. But one thing is for sure, we all love (and need) our trucks, farm or otherwise."
