Grab a pen and put a dash on your calendars, December 2010 marks the dawn of a new era in diesel fuel. From this month forth, all diesel pumps in the U.S. are required to dispense nothing but ultra-low sulfur diesel (ULSD) for highway applications. The multi-year switch to ULSD has allowed automakers to design oil-burning vehicles with complex emissions control technologies that have the ability to substantially lower the amount of particulate matter they emit, leading to cleaner-running automob

The National Renewable Energy Laboratory (NREL) has just completed the first year of a study comparing St. Louis transit buses running on B20 biodiesel and ultra-low sulfur diesel (ULSD). Surprisingly the B20 buses actually had slightly lower average mileage than the ULSD fleet, 3.52 vs 3.58 mpg. The new study is the first to examine B20 use on buses equipped with exhaust gas recirculation systems. The EGR helps to reduce NOx emissions. Fifteen identical buses were examined in the study with

The discussion of a global (or at least national) standardized biodiesel is one thing that OEMs are waiting for to further embrace the biofuel. But even long-standing diesel fuel is different depending on where in the world you're buying it. The International Fuel Quality Center (IFQC) - yes, there is an International Fuel Quality Center - has taken a look at the ultra low sulfur diesel (ULSD) standards of 100 countries and to find the countries that allow the least amount of sulfur. The lowest

I was filling up yesterday and noticed a sticker on the diesel pump warning about the damage the low sulfur fuel might do to new engines that I wanted to know a bit more about. If you're a regular diesel-fueler, you might be used to this warning, but I'm not and wasn't. Since I was curious, I thought some of our readers might be, too.

Today's press release from Ford about the company's "New 6.4-liter Power Stroke® diesel" engine is not the first time we're hearing about the "Cleanest, Quietest Power Stroke Engine Ever." But, with Ford's Clean Diesel Technology, the engine now is more powerful and cleaner than ever before, something Ford is quite proud of. The company's Diesel Powertrain chief engineer, Rick Renwick, says that, "No diesel engine has ever delivered this much power and refinement with such clean emissions. W

Back in 1999 and 2000, the EPA issued the requirement that all US diesel fuel sulfur content be reduced 97 percent from 500 part per million (ppm) to only 15 ppm by 2007. The purpose was to a) reduce emissions in all existing diesels moderately with no harm to them and b) to allow the installation of NOx reducing components in 2007 that would otherwise be poisoned by the higher sulfur content. The petroleum refiners and the engine makers resisted strongly but the EPA held its ground and the regu

The National VegOil Board (NVOB) has got some new updates for people in the VegOil (or WVO, or SVO, of whatever you want to call it) community.

With the advent of Ultra Low Sulphur Diesel and other emissions and particular matter reducing technologies, diesel is back in a big way in markets like the U.S. and down here in Australia. Of course the clear advantage diesel has over petrol in fuel economy is old news to the Europeans where favourable taxation rules have seen diesel passenger vehicles compete head to head with petrol vehicles for a long time. This huge market at home has meant that the European car makers have led the world in

Diesel Technology Forum has released a new PDF white paper designed to give diesel users a comprehensive overview of how diesel technology and regulations are changing to reduce diesel emissions. Covered are the new diesel emissions standards and the introduction of Ultra Low Sulphur Diesel (ULSD), as well as a number of techniques that can be used for upgrading existing diesel engines to reduce emissions.

New Ultra Low Sulfur Diesel (ULSD) fuel, which is now widely available in America, may costs more to produce and purchase, but school districts near Pittsburgh are willing to spend money to get the benefits of the cleaner fuel. In this story from the Pittsburgh Tribune-Review, for example, the number for the North Allegheny School District and others are explained.

Well, Ultra Low Sulfur Diesel (ULSD) has been readily available all of three days, let's argue about it. Yesterday, the president and CEO of the American Chemistry Council, Jack Gerard, issued a statement saying that U.S. lawmakers need to change the policy regarding access to domestic natural gas sources if we're going to keep making ULSD. Why is this, you ask? Because you can use hydrogen to desulferize diesel fuel. So while we've now got diesel engines that emit up to 90-some percent fewer pa

This post was supposed to appear yesterday, but thanks to the 6.7 magnitude earthquake here in Hawai?i, I wasn't able to get online at all. Thankfully, it seems that the quake didn't cause much damage and no fatalities, and being without power or Internet for a day isn't really a hardship, now, is it? Especially when you can go out and take pictures of people responding to the situation (which is what I did, and discovered people charging $5 for a lunch of rice and boiled eggs. Wow).

It's here! The next important step on the path to new clean diesel in the U.S. has occurred today, October 15th. It was by today that 80 percent of diesel fuel available for vehicles like trucks and buses had to be new Ultra Low Sulfur Diesel (ULSD), and reports are saying that implementation of the new fuel has so been so swift that today it stands at 90 percent. Back on June 1st refiners and fuel importers were required to start producing ULSD, and last week production of the clean diesel rose

By now most diesel fuel already in the pipeline is meeting the new federal standards for sulfur. But the official nationwide switch to ultra-low sulfur diesel (ULSD) fuel is Oct. 15. To mark the occasion, Cummins hosted EPA administrator Stephen Johnson to the company's test facilitiy.

June 1st marked the first important step towards the ultimate phase-in of Ultra-Low Sulfur Diesel (ULSD) fuel in the U.S. by 2010. As of the first of this month refiners began producing cleaner-burning ULSD fuel for use in highway vehicles such as big rigs and buses. All 2007 and later models of these highway vehicles will be required to use the new fuel by law. Using currently available Low Sulfur Diesel fuel will not only harm these new engines, but is also illegal and may result in civil pena

One of the problems with using fossil fuels is the sulfur that gets sent out the tail pipe. Clean diesel is one way to power diesel engines without the sulfur. The technical definition, explained over at the Diesel Technology Forum, is Ultra Low Sulfur Diesel, which means the fuel contains only 15 parts per million sulfur content, 97 percent less than current diesel. ULSD should be available to most consumers by October, and last Thursday was one of the first in a series of deadlines to get ULSD
