Navy to Build Two New Oceanographic Research Vessels

Wed, 22 Feb 2012 16:02:00 -0400

Designed as single hull ships, AGOR 27 and AGOR 28 are approximately 238 feet long and incorporate the latest technologies, including high efficiency diesel engines, emissions controls for stack gasses, new information technology tools both for monitoring shipboard systems and for communicating with the world, and hull coatings to reduce maintenance requirements. Each vessel will operate with a crew of 20 with accommodations for 24 scientists.

Ron Freeland To Head DDOT, New Green Buses Unveiled

Wed, 22 Feb 2012 16:02:00 -0400

The city is set to get 46 new green vehicles, made in the United States by the Gillig Company. They feature energy efficient diesel engines that emit up to 90 percent fewer exhaust emissions than older buses in the fleet.

Cruze Diesel Will Build on GM's Euro Expertise

Tue, 21 Feb 2012 17:02:00 -0400

GM sold more than half a million diesel powered cars across Europe, Asia, Africa and South America last year, including 33,000 Cruzes. The introduction of a diesel option for Cruze – one of the top selling gasoline powered cars in the United States in 2011 – is expected to fuel GM's diesel car sales success. Diesel engines have long been known for their fuel efficiency and power. Due to a higher compression rate in the engine cylinders and greater density of energy in diesel fuel itself, diesel powered engines are able to produce more power per gallon than gasoline powered engines.

More Chevy Cruze Diesel Details Emerge

Tue, 21 Feb 2012 16:02:00 -0400

For 2013, Chevrolet will add a diesel powertrain to its already popular Chevy Cruze compact sedan. Today we confirmed with GM Powertrain spokesman Tom Read that the diesel engine will have a 2.0 liter displacement and be turbocharged. In Europe, the Cruze already has a turbocharged 2.0 liter VCDi diesel inline four that makes 161 horsepower and 266 pounds feet of torque. This could very well be the engine that ends up in the U.S. model, but with some modifications.

Use of Clean Diesel Technology has Helped Reduce Emissions 90% Over Past 10 Years

Tue, 21 Feb 2012 16:02:00 -0400

"These historic environmental improvements take an even more important significance when you consider that over 80% of all freight in the U.S. is moved by diesel powered trucks, railroads and marine vessels," said Allen Schaeffer, Executive Director of the Diesel Technology Forum. "Whether it's a delivery truck bringing a package, a freight truck rolling down the highway, or a train carrying coal, merchandise and automobiles, you can bet a diesel engine is powering the vehicle."

In the Past 10 Years, Emissions From Diesel Trucks and Buses Have Been Reduced By 99% for NOx and 98% for Particulate Emissions

Tue, 21 Feb 2012 12:02:00 -0400

As the U.S. economic recovery continues to move forward, new clean diesel technology is powering America's freight movement in the most environmentally friendly manner anywhere in the world, according to Allen Schaeffer, Executive Director of the Diesel Technology Forum. "Over the last 10 years, emissions from heavy duty diesel trucks and buses have been reduced by 99 percent for nitrogen oxides (NOx) an ozone precursor and 98 percent for particulate emissions," Schaeffer said. "Consider that it would take 60 of today's clean diesel trucks to equal the same emissions from one pre 1988 t

Media Advisory: Press Conference to Outline Major Clean Air Innovations In New Clean Diesel Technology at CALEPA Building in Sacramento

Mon, 20 Feb 2012 13:02:00 -0400

The air in neighborhoods throughout California has become significantly cleaner thanks to major advances in clean diesel technology and ultra low sulfur diesel fuel. On Tuesday, February 28th, officials from the California Air Resources Board (ARB), leading diesel equipment manufacturers and Diesel Technology Forum will explain how the cooperative effort between state officials and industry has led the transition to "clean diesel" in large part due to the landmark regulations advanced by California and the ARB.

Making Cars Carnivores: Tyson Venture Turns Animal Fat Into Diesel

Fri, 17 Feb 2012 17:02:00 -0400

This week meat giant Tyson Foods and fuel maker Syntroleum announced that their Dynamic Fuels joint venture was selling millions of gallons of animal fat based diesel to Norfolk Southern railroad to power freight trains. The diesel they make is what's known as a "drop in" fuel — meaning you can use it as a direct substitute for regular diesel. Plus, it's higher quality, with cetane levels as high as 88. Cetane is the equivalent of octane in gasoline; the higher cetane, the more evenly and more powerfully the fuel combusts. The average diesel has a cetane level of less than 50. The fuel also

Environmental Stewardship Earns Coach USA Prestigious Award at Industry Event

Thu, 16 Feb 2012 17:02:00 -0400

Coach USA continues to update its fleet with newer coaches featuring the latest clean diesel engine technology and emitting near zero emissions. The company is also testing new technologies that offer four to six percent reductions in fuel usage, and it equips its fleet of 1,642 coaches and buses with GPS systems that trigger alerts through the company's command center when idle times are exceeded.

Quotable quotes from various speakers at the National Biodiesel Conference last week in Orlando

Wed, 15 Feb 2012 17:02:00 -0400

Tom Fulks of the Diesel Technology Forum, who appeared in place of the organization's executive director Allen Schaeffer, said in the context that Washington knows biodiesel exists and is fighting to grow, "Make sure they cut you less than everyone else." Fulks said Texas and California are the largest diesel car and truck markets in the U.S. He also noted how drastically diesels have changed in just the past five years as emissions controls and engine and systems technologies have ushered in the clean diesel era. As a testament to how clean diesels truly are today, Fulks told the audience tha

Which engine is more efficient: a diesel engine or gasoline engine?

Tue, 14 Feb 2012 14:02:00 -0400

Diesels are 30 to 35 percent more efficient than gasoline engines, according to the U.S. Department of Energy. Diesels operate at higher compression ratios and at higher temperatures than gas engines, promoting more complete combustion and greater thermal efficiency — meaning you will go further on every gallon of fuel. In addition, diesel fuel has about 14 percent more energy by volume than gasoline, so it takes less fuel to generate the same amount of power.

EPA''s 2013 Budget Proposal Is "Penny Wise and Pound Foolish" in Further Slashing of Successful Diesel Emissions Reduction Efforts

Tue, 14 Feb 2012 14:02:00 -0400

The proposed 50 percent reduction in funding for the Diesel Emissions Reduction Act (DERA) in the Obama Administration's 2013 proposed budget is "penny wise and pound foolish when it comes to one of the country's most successful clean air programs," Allen Schaeffer, Executive Director of the Diesel Technology Forum, said today.

Automakers press for some changes to fuel rules

Mon, 13 Feb 2012 14:02:00 -0400

German automaker Porsche AG —a member of the auto alliance —told the Obama administration in separate comments that it should not favor EVs over diesels. "Many (automakers), including Porsche, plan to introduce diesel technology as a major component of their compliance strategy," the automaker wrote. It also said that EPA and NHTSA "grossly underestimate the cost of battery technology."

UM Study: Fuel Economy Continues To Rise

Sun, 12 Feb 2012 14:02:00 -0400

The fuel economy of new vehicles continues to rise according to one university study. The study found that average fuel economy: Improved 9.8 mpg for diesel engines and 2.6 mpg for conventional gasoline engines, but dropped 3 mpg for hybrids, which are still more fuel efficient overall than internal combustion only vehicles.

Big drop in diesel emissions at Port of Oakland

Thu, 09 Feb 2012 15:02:00 -0400

Beginning in January 2010, drayage trucks with engine year models between 1994 and 2003 were required to be retrofitted with a diesel particulate filter to enter Port of Oakland maritime facilities. The filter is verified by the California Air Resources Board (CARB) to reduce a truck's diesel emissions by at least 85%. CARB, the Bay Area Air Quality Management District (BAAQMD), the Environmental Protection Agency (EPA) and the Port of Oakland funded grants for truck retrofits and replacements.
