Wal-Mart Stores, Inc announced plans to test two different hybrid Class-8 trucks and three different types of alternative fuels in an effort to double their fleet’s fuel-efficiency. Read the rest of this entry »
The name of Ford’s new V6 engine seems to imply that power is somehow boosted by some naturally occurring and environmentally sustainable green technology, like tree leaves, or a river. Cars are a long way from being environmentally friendly, regardless of the technology that’s been developed and put into hybrid and electric cars. Electrical outlets don’t grow own trees, and in fact, much of the electricity we use is powered by coal, not exactly a clean or sustainable technology.
UPS will field two hydraulic hybrids in Minneapolis, MN, in early 2009 and an additional five hydraulic hybrid trucks will be deployed later in 2009 and early 2010. Although this sounds like a tiny fleet, keep in mind that this is the largest scale commercial test of hydraulic hybrids ever conducted.
The UPS hybrid hydraulic truck is a standard-looking 24,000 pound package car, with an EPA-patented diesel series hydraulic hybrid drive attached to the rear axle.

Even though Tesla is delivering their cars to consumers several years before the Volt hits the show rooms, from the perspective of Dan Santini, you and I are more likely to get our hands on Volt-style vehicles first.
Some of the main obstacles that stand between us and pure EVs were identified at the 1st International Conference on Advanced Lithium Batteries for Automotive Applications, sponsored by the Argonne National Laboratory (where Dan Santini works). Read the rest of this entry »
Although Ford’s first generation Ecoboost engines start hitting the market next year — promising a 20% gain in fuel economy over traditional engines — Ford is already tweaking their new Bobcat technology to squeeze out even more fuel efficiency from the direct ethanol injection system.
The technology works by merging a turbocharger with a high compression ratio in the same engine. Combining these two features normally results in an incompatible and disastrous mix which causes premature detonation of the fuel/air mixture — referred to as engine knock.
Recently, I wrote about how biodiesel’s new ASTM standards could go a long way in improving warranty coverage for biodiesel use in your new car. NW Biofuel’s letter goes into a little more detail, and gives you a reference you can give to your dealership or keep in the glove box. Here’s what you should know:
Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they’ve created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a conventional internal combustion engine of the same horsepower. Oh yeah, did I mention that it doubles the fuel economy too.
What that means is a car like the 2007 Toyota Yaris, which is rated at 40 mpg on the highway, would get 80 mpg with a Revetec engine.
This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims.
There are more than 5,000,000 heavy duty trucks running up and down US highways each day. Every one of those trucks gets an average of 7 mpg, carries upwards of 200-300 gallons of diesel, and spews out potentially harmful emissions.
Like it or not, we depend on them to bring us our food, fuel, and products for everyday living. It’s a connection that most of us often forget about, only remembering it long enough to curse them as they slow us down on the highway.
It’s also an industry that has recently been hit hard by soaring fuel prices, and now, with the average price of diesel in the US at $4.70/gallon and climbing, it’s sure to get worse.
Needless to say, there’s a rising cacophony of voices within the trucking industry clamoring for relief. Most of this noise currently comes in the form of wanting a break in fuel prices, but really that’s just a temporary fix. Any solution with sticking power would have to offer both economic and environmental benefit — you know, win-win.
As the automakers scramble to make plans for achieving 35 MPG by 2020, it seems that our suspicions that the task is entirely possible without fancy hybrids or hydrogen cars has been confirmed. The manufacturers been achieving high mileage in Europe and Japan for years now, so I expect to see it in the US eventually. Luckily, there are six exciting new technologies that are going to make it possible in the US.
These technologies are interesting because they come without the paradigm shift that seems to accompany buying a hybrid or a small economy car. Cars equipped with this green tech will be just like any other car, just more efficient.
More on the six new engine technologies after the break.
It’s not quite the same type of hybrid drive-train you’d see in street vehicles, but in an exciting announcement, Max Mosely of F1 has announced that all cars will become hybrid by 2013, along with other changes to the vehicles.
The hybrid system that will be phased in is known as KERS, which stands for Kinetic Energy Recovery System. KERS doesn’t store as much energy as a traditional hybrid system, but it only weighs 55 pounds and the limited energy storage capacity is well suited for Formula-style racing.
