Is Toyota Preparing to Bring a Hybrid Diesel to America?

Yesterday we wrote about some of the new technology created to reduce or eliminate emissions on diesel trucks. In today's story we'll discuss another innovation that 50 years ago would probably never been imagined--a hybrid diesel truck.

The first story that caught my eye was this one at Gear Junkie titled, US Hilux? Toyota Poised to Launch Diesel Trucks in America. It's actually two stories rolled into one. The first story has to do with buzz generated by a new patent application that had been filed by the Japanese manufacturer, Patent No. US2020020860 for a new kind of internal combustion engine. (Did you know that the U.S. Patent Office considered closing at the turn of the last century? They believed so many inventions had been patented there couldn't possibly be anything new.)

The story doesn't end there. Rumor has it, according to Gear Junkie, that Toyota may be eliminating the Diesel Particulate Filter and Diesel Exhaust Fluid with an alternate to glow plugs and a re-designed injection nozzle.  

That's not all. The Toyota Tacoma has a cousin called the Hilux. Of the Hilux author Sam Anderson writes: "The 2022 Toyota Hilux has a 2.8L 1GD-FTV I-4 turbodiesel with 174 horsepower and 273 pound-feet of torque. The turbodiesel impresses in the crawl: Full torque is available as low as 1,200 RPM. Alternatively, a small-displacement 2.4L engine provides 148 horsepower and 295 pound-feet of torque."

In short, Toyota engineers have talent. But their marketers are equally sharp. Their response to the increasingly stringent environmental demands on cars and trucks is to deliver a hybrid truck. That's right. The hybrid Hilux will purportedly produce 200 hp and 350 pound-feet of torque.

Anderson admits some of this is rumor, but Toyota has been shifting gears for a while and it's not impossible to connect dots on where they are going. The company announced last year that they were phasing our their V8 engines.

Anderson examines various scenarios that might play out with regard to Toyota's various truck brands, the Tacoma, Tundra and Land Cruiser, though in the end he states that it is impossible from this vantage point to know what Toyota's coming truck lineup will look like.

More About Hybrids
Interestingly enough, two additional stories about hybrid diesels crossed the wire today. One has to do with the development of a hybrid tractor trailer in Canada. The other was published in at a popular investment site, The Motley Fool

Chelsey St.Pierre's article in The Suburban is titled "Scarpallegia announces investment in Pointe-Claire hybrid tractor-trailer project." Francis Scarpallegia is a member of Canada's Parliament who spoke on behalf of the Minister of Natural Resources announcing a $1.7 million investment in FPInnovations to develop and demonstrate a hybrid diesel-electric forestry truck.

There's a certain logic to all this. If you are entirely EV and get stuck in the North Woods with your power drained, what are your options? But if you have a hybrid, you will be far more self-sufficient and less worried about the low juice reading on your battery. 

The real driver, of course, is reduced emissions. Fuel savings are also significant if this project comes to fruition. You can read more about what FPInnovations is doing here.

The last story is titled, "Hyliion: We're On Track to Launch Next Year, No Additional Cash Needed." Hyliion is a truck drivetrain company that is preparing to ship a hybrid-semi system later this year. The Texas-based publicly traded company is getting ready to supply lower-emissions drivetrains that can be fitted onto heavy duty trucks by the six leading global truck manufacturers, familiar names to Blue Flame blog readers.

The MF article focuses on the company as an investment, but provides some keen insights as regards the EV revolution. This intermediary period of hybrid diesel-EV trucks is happening in nearly every truck category, from personal rides to heavy duty workhorses. Here's where you can find the rest of this story from the Motley Fool.

Diesel Exhaust Fluid (DEF) -- What Is It and Why Is It Necessary?

In December we discussed DEF and its role in today's enviro-sensitive times. At the end of July a similar story by Kyle Hyatt was shared on a Road/Show podcast. It's an important subject and worth visiting again. In fact, the title suggests it's more important than ever.

Diesel has been on the receiving end of a lot of bitter barbs in the past, chiefly due to the black exhaust associated with older diesel trucks and buses. Things have changed significantly, however. As is well known, the black-smoke-belching smokestacks of Pittsburg stank the city a century ago are long gone and its beautiful, vibrant hills encircle it today. In the same way, diesel vehicles have been undergoing a image renovation, making diesel viable for years to come.

According to Hyatt, 2010 was a critical year for long-haul truckers and fleet managers when the EPA mandated the use of selective catalytic reduction (SCR) in diesel engines. The reason this development was unsettling is because what makes SCR work is a consumable called diesel exhaust fluid (DEF). This would not only add cost, but also add an added maintenance step. Not the end of the world, but t would be an additional inconvenience.

Things turned out better than expected, however. Instead of resisting change, engine manufactures embraced it and found they could continue to make reliable engines. Not only that, the new technology that was incorporated reduced emissions so much that topping off the DEF now and then wasn't such a hurdle after all.

In the next section of the article Hyatt explains how the SCR works and the role of DEF to make it happen.

He begins by noting that selective catalytic reduction isn't new. It's actually been around for half a century, initially used to reduce pollution from coal-fired power plants. The primary pollutants were nitrogen monoxide and nitrogen dioxide, which are also the problem with diesel combustion.

The author goes into detail on how SCR works. First, exhaust gas must be filtered to remove soot and ash. Then the exhaust gas flows past a nozzle that sprays DEF into the stream of gases. (DEF is primarily water and urea, which you can read more about here.)

The hot exhaust gas and DEF enter the catalytic converter where a chemical reaction takes place, magically converting the nitrogen oxides to nitrogen and water. You may recall from your chemistry class in high school that the air we breathe is nearly 80% nitrogen. In short, it's gas that is harmless to our environment. 

The details are oversimplified here but will give you a sense of the chemistry and technology involved. It's a variation of what a car's catalytic converter does. Hyatt states that "Most modern diesel engines use SCR in combination with exhaust gas recirculation and a diesel particulate filter (DPF) to reduce emissions."

Exhaust gas recirculation (EGR) is now used  in nearly all modern ICE engines as a means of eliminating unburnt fuel. But this process also has handicaps and engine manufacturers are striving to find the right balance between EGR and SCR. The target is the elimination of emissions in a manner that doesn't hamstring performance and fuel economy.

Are there any downsides to DEF? You might think the hassle factor and cost are downsides, but since you only need to refill the tank about as often as you change your oil, that's not much of an inconvenience. As for cost, it's not really expensive.

Because of the increased implementation of this technology it is helpful to understand why it has been adopted and how it works. Emissions systems are becoming increasingly critical. According to the WSJ today, the current stimulus package includes a section in which every public company in the U.S. might be required to report climate information such as emissions and greenhouse gases related to their products and their climate risks. 

Near the end of this story Hyatt states that the achievements in diesel will prod U.S. truck manufacturers to offer more diesel models in traditionally gasoline-dominant market segments. We've already reported on some of this.

The author sums up his story with this observation of note:

"Where DEF really becomes critical is in big diesel engines. We don't mean like your Cummins 6BT, we're talking Class 8 semi-trucks. These vehicles do millions of miles over their lifespans, and their massive diesel engines go through a lot of fuel in that time. These vehicles go through a lot of DEF as you might imagine, so at truck stops, DEF is sold at the pump."

XDP Story Features Upgrades for the Diesel-Powered 2001-2004 GM 6.6L LB7 Duramax

It's well known that General Motors had a few stumbles with regards to early efforts to produce diesel vehicles. Fortunately they found their footing and for many, the Silverado is golden. 

In June XDP published an informative story on the 2001-2004 GM 6.6L LB7 Duramax. The article begins by noting how the heavy-duty truck scene was altered when Dodge teamed up with Cummins. A dozen years later, GM introduced a diesel engine that would make them a contender in the diesel market. Introduced in 2001, the superior Duramax replaced the Detroit Diesel 6.5L, incorporating state-of-the-art technology.

According to the XDP story, the design of this new engine was initiated four years earlier when GM and Isuzu linked arms to create a partnership called DMAX Ltd. Production of the LB7 commenced three years later. The 6.6L V8 had four valves per cylinder and delivered 300 hp along with 520 lb-ft of torque.

This was a revolutionary engine, with turbocharger, intercooler and direct injection (features that are commonplace today but were not at that time.) Its most significant feature was the use of common rail technology developed by Bosch, a first amongst the big three, two years before Dodge and seven before Ford. The engine was also lighter, with aluminum cylinder heads. Ford adopted lightweight aluminum cylinder heads a dozen years later in its 2011 Powerstroke.

The author places a spotlight on the real "star of the show" for many enthusiasts. The Allison 1000 was "arguably the first automatic transmission in its class worthy of being mated to a diesel." In short, it was a marriage made in heaven. 

If you preferred a manual, instead of the 5-speed Allison tranny, you could choose a ZF 6-speed manual. The Allison 1000, however, became the more popular choice.

The new LB7 Duramax was available in some of the other GM brands including the GMC Sierra 2500HD and 300HD, and the medium duty Chev Kodiak and GMC TopKick. In addition to the engine and drivetrain upgrades there were also some new body styles introduced. The author goes into detail on many of these features as well.

The article is actually a Buyer's Guide with XDP noting out the pros and cons of this iteration of the Silverado. The biggest problem had to do with the LB7 fuel injectors. The fuel injector problems were so common that they had a recall to replace them with an updated design. Warranties helped keep GM owners from bailing out completely. 

XDP cited the primary pros and cons as follows:

Pros
Allison Automatic Transmission
IFS For a Smooth/Comfortable Ride
Common Rail Fuel System with CP3 Pump
Different Exterior Styling Choices (’01-’02 Silverado, ’03-’04 Silverado, or GMC Sierra)

Cons
Body/Frame Rust
Weak Tie Rod Ends
Brake/Fuel Lines Prone to Rust
Factory Dowel Pin that Holds the Harmonic Balancer in place can Shear.

* * * 
The latter part of the article--Popular Aftermarket Upgrades--is really the meat of the story. Everything else is setup, laying the foundation for readers to make informed decisions.

If you have a 2001-2004 GM 6.6L LB7 Duramax, this is a highly informative Buyer's Guide piece that you may wish to read and bookmark. Check it out here: https://tinyurl.com/hz7k6ktc

New Diesel Engine Oil Technologies Lead To Improved Performance and Efficiency

Photo by Josiah Farrow on Unsplash

Since the mid-1970s the U.S. government has taken on the role of setting standards for fuel efficiency and reduction of emissions. In 1975 Congress implemented Corporate Average Fuel Economy (CAFE) standards, which has been a driver for much of the change that has occurred in engine design during the past five decades. The trigger at that time was the OPEC oil embargo that caused shortages and a spike in fuel prices, so the initial standards were more focused on fuel consumption.

Efforts to reduce emissions gradually increased in importance in subsequent decades. Along with engine design improvements it became apparent that more advanced lubricants were needed to achieve the goals being required by the National Highway Transportation Safety Administration (NHTSA) and the Environmental Protection Agency (EPA)

Near the end of July Fleet Owner magazine published a story about emissions efficiency related to new diesel engine oil technologies. The aim of this story is to help fleet owners and managers understand the new formulations being introduced to satisfy global fuel economy targets. What follows are some highlights from this article.

An engine oil's main task is to reduce friction and ensure that moving parts are kept from coming in contact with one another. (This latter function is why film strength is increasingly important.) Oil is also necessary to transfer heat away from the engine and remove impurities and debris that might collect on critical parts.

With the technical advances taking place in diesel engine, driven by the need for greater efficiency, the lubricants are experiencing greater stress. Not only must they perform under harsher conditions for longer oil-drain intervals, they must do so in the presence of biofuels, without compromising protection.

In recent decades we've seen the introduction of significantly thinner oils for automobiles. It's been recognized that there are also gains to be made in the heavy duty truck market by means of lower-viscosity oils. How far can one go without compromising engine durability?

The rest of this article presents the results of field trials by Shell pertaining to fuel economy in Class 8 trucks. The data they have analyzed is drawn from 39 million miles of testing with CK-4 and FA-4 technologies. (See: Understanding CK-4 and FA-4) 

The first benefit is that lengthened oil drain intervals can result in major oil savings for fleets due to fewer oil changes. Using a higher quality oil, as opposed to one meeting minimum standards, drain intervals would nearly double and oil usage nearly cut in half.

A higher quality diesel engine oil is more impervious to oil breakdown, which makes longer oil drain intervals possible. The majority of these oils use synthetic or hybrid basestocks. The article details Shell's tiered offerings for the various engine types. You can find the Champion Brand diesel oils for your application here.

This Custom-Designed Diesel-Powered Land Rover Served Britain's Prince Philip Well

Photo Steve Parsons. Getty Images. No copyright infringement intended.

With our editors on vacation, we're re-posting a few of our favorite stories from the previous year. This story, published this spring, caught a lot of eyeballs. 

Funerals are a pretty big deal when it comes to the rich and famous. This is especially so when royalty is involved That is why we saw news stories from nearly every angle regarding the the funeral of Prince Philip, Duke of Edinburgh. Most of these were articles about the life of Philip, of course, but also articles detailing the history of royal funerals through the decades, the dress code for such funerals, the things that are different from normal because of the pandemic, decisions made that may be unexpected, guest lists and other details that must be attended to.

And then there is the story of Prince Philip's custom-designed diesel-powered Land Rover that will serve as his hearse. 

I've heard of people building their own coffins, but this is the first time I've ever heard about a personally-designed hearse. It is a Land Rover that the prince has been tweaking for 16 or 18 years, depending on which news source your read. Either way, it's actually quite a story.

The Duke driving a Land Rover with the Queen in 1955.

It's well known that people who love Land Rovers really love them. They're dedicated. When Prince Philip began to consider his mortality, and all the fanfare that goes along with royal funerals, he simultaneously began sowing the seeds for a no-frills funeral, starting with the hearse itself. "Just stick me in the back of a Land Rover and driver me to Windsor," he purportedly told the Queen.

Specific decisions made by Prince Philip include the military green paint job, the open top rear, and special rubber grips on silver metal pins to hold the coffin in place. The vehicle itself is a Land Rover Defender TD5 130 chassis cab vehicle. Revealed Thursday for the first time, it generated much publicity on it own. 

According to Sky News, the Prince began the project in 2003 when he turned 82, working directly with Land Rover to get what he wanted. The selection of a 4-wheel drive Defender is intriguing. The Defender, introduced in the 1980s, was in 1998 fitted with a new 2.5-liter, five-cylinder inline turbodiesel engine badged the Td5, which replaced the Tdi in order to meet Euro III emissions regulations. Called either a straight five or an inline five, the cylinders are aligned in a row. It's both compact and efficient, using electronic control systems to produce 122 hp at 4850 rpm.  

There's symbolism in the selection of this vehicle. It's not ostentatious. It's sturdy and utilitarian, a functional vehicle for the common man. The Duke of Edinburgh was so enamored by the idea of using the Land Rover as a hearse that he made two backups in case something went wrong with the first during the intervening years from concept to this moment in time.

Throwback Thursday: Towing Insights We All Can Use

With our editors on vacation, we're re-posting a few of our favorite stories from the previous year. This story was published this past November.

One of the primary features of diesel engines--besides the fact that they last longer--is the power they generate for towing. Open your eyes and look around. What kinds of engines are doing all the work? It's diesel. 

So, whether you're towing horses to the county fair or hauling a bulldozer to a job site, your truck is likely a diesel powered machine.  

Having the right engine isn't the only thing you need to know about towing. While checking out the Diesel Power Products website yesterday I found this article on towing that was chock full of useful information for people who tow. Having written about towing in the past, I found it to be a fairly thorough discussion of issues you need to concern yourself with. These include:

Attaching the Load

Stopping the Load

Supporting the Load

Securing the Load

Balancing the Load

and Moving the Load

Years ago I heard a story about a bulldozer that slid off the back of a flatbed and killed two people because it wasn't properly secured. This is not an experience you want to have. When I was young I saw an inexperienced driver flip her car while towing a small house trailer. I was with my uncle who was a volunteer fireman and rescue squad worker. We were first on the scene and helped avert a bigger tragedy. 

If you ever do any towing, or plan to, this helpful article on The Basics of Towing with Your Diesel is informative and worth bookmarking.

Champion Blue Flame Diesel Engine Oil Recommended for Limited-Edition Shelby F-250 Super Baja Pick-Up

With our editors on vacation, we're re-posting a few of our favorite stories from the previous year. This story appeared in March.

In February the story broke about the new Shelby F-250 Super Baja Limited. It was a fun story because for many, this is what dreams are made of. The name alone is iconic, in part because of its celebrated history. It's not every day that you see a car designer featured on the silver screen. (Ford v. Ferrari) Then again, the Shelby story really does at times appear to be bigger than life.

So it with special enthusiasm that I read yesterday's news headline: 

Champion Blue Flame Diesel Engine Oil Recommended for Limited-Edition Shelby F-250 Super Baja Pick-Up 

Here's the rest of the story.

Champion Oil, a global leader in performance diesel engine oil now celebrating its 65th anniversary, announced that Shelby American is recommending Blue Flame Diesel Engine Oil  for its new Ford Shelby F-250 Super Baja, a Limited-Edition off-roading pick-up truck. 

“We deigned the Shelby F-250 Super Baja pickup to perform under extreme conditions, both on and off-road," said Gary Patterson, president of Shelby American. “With 6.7-liter V8 Power Stroke Turbo Diesel churning out 475-horsepower and 1,050 pound-feet of torque, the truck can really fly. For such an aggressive application, we recommend using Champion’s Blue Flame 15w40 CK4/SN Performance Diesel Engine Oil."  

Built for Shelby in Elkhart, Indiana, by Tuscany Motor Co., and in Las Vegas by the Shelby American team, the trucks will be sold at select Ford dealers in the U.S. Each will be documented in the official Shelby Registry. Production will be limited to only 250 vehicles.

Blue Flame Diesel Engine Oils are formulated with workhorse high-zinc performance additives, superior protection, advanced polymer technology, and high TBN, supported by a carrier blend of synthetic fluids. The Shelby F-250 Super Baja needs a total of 13 quarts of oil including the capacity of the oil filter.

In addition, Blue Flame Diesel Engine Oils deliver unmatched high temperature film strength and lubricity protection, with the muscle to combat oil shear and maximize sustained cylinder compression. They also inhibit oxidation, corrosive acids, sludge and varnish build-up. 

These robust performance oils keep diesel engines going longer by reducing soot-induced engine wear, controlling abrasive soot contamination and preventing high temperature corrosion, even while allowing for improved fuel economy and lower total cost of ownership. They are proven to increase engine horsepower and torque. https://www.championbrands.com/diesel-engine-oils/
