New Jersey Governor Chris Christie has signed a law making rolling coal illegal in the state. The bill was introduced less than a year ago after a pickup belched soot on a State Assemblyman's Nissan Leaf.
A study analyzing real-world diesel vehicle emissions finds that NOx levels from modern engines far exceed the mandated limits. However, the carbon monoxide and total carbon hydrogen numbers are where they should be.
A newly released study finds that the emissions from post-2007, EPA-compliant diesel engines do not show risks of causing lung cancer in lab rats. The animals were exposed to the exhaust for 80 hours a week for up to 30 months. Previous studies have shown much more adverse effects from older diesels.
The US will soon work with China as the world's most populous nation works to draft stricter emissions standards. The two countries certainly know how to put pollution into the air – China is the world's biggest emitter polluter, followed by the US.
Our economy runs on diesel. It's burned in the road-going rigs that bring us everything from potatoes to potpourris. If it's on a store shelf, it likely arrived by oil-burning truck. Increasingly, diesel engines are also finding a home in our passenger cars, migrating from Europe, where they've long been popular.
Before you head to the pharmacy to refill your Lipitor prescription, check this out. The American Heart Association's journal on Arteriosclerosis, Thrombosis and Vascular Biology has concluded that high levels of vehicle emissions can cause high cholesterol in mice, which could indicate that air pollution is a contributing factor in high cholesterol or vascular disease.
Although no one ever believed that inhaling black, grit-filled smoke would do you any favors, the World Heath Organization notes that doing so is much worse than merely unkind: the WHO has officially decreed that inhaling diesel fumes can cause lung cancer and has added the fumes to its list of Group 1 Carcinogens, those known to cause cancer in humans. That puts diesel plumes in the same homicidal company as arsenic, strontium-90, neutron radiation and being a painter, and makes it worse than s
BMW wants to take another look at over 24,000 vehicles it's sold in the United States. No, this isn't just to check out how they're holding up in the real world, it's to make sure the smoke coming out of the tailpipe is clean enough.
In what might be considered one of the worst bits of info related to diesel engines, medical researchers at the University of Edinburgh say that chemical particles (aka particulates) exiting the tailpipe of diesel-fueled vehicles can significantly increase the risk of heart attack in otherwise healthy adults.
A recent UCLA study analyzed the performance of retrofit systems for diesel-fueled school buses and discovered the systems significantly reduce tailpipe emissions, but had no measurable effect on in-cabin pollution.
On February 11th, the California Dump Truck Owners Association (CDTOA) filed a lawsuit against the California Air Resources Board (CARB), challenging the legality of a statewide rule that requires truck and bus owners equip their rigs with diesel exhaust filters and, eventually, to replace pre-2010 engines with emissions-compliant mills.
According to a London Assembly report, air pollution in the UK capital may have contributed to the deaths of some 3,000 people in the year 2005. Further, while not as important as the health of London's populace, the report estimates that these health-related issues cost £20 billion per year to treat. The main culprit for the city's poor air quality? Diesel engines. Says Darren Johnson, Chair of the London Assembly's Environment Committee:
While most customers don't need to worry about exactly what the emissions standards are for their diesel vehicles, manufacturers and those keeping a strict eye on CO2 emissions do. For consumers, the upcoming stricter standards on diesel vehicles in the United States mean cleaner, more efficient cars. For manufacturers and engineers, it means figuring out how to stop the CO2 from getting into the air. How much CO2, you ask, well, that's what the Tier 2 regulations tell us (Tier 2 regulations app
Toyota is working on ultra-clean diesel engines independently from their recent hook-up with Isuzu. Similarly to the United States and Europe, Japan is introducing stricter emissions requirements for diesel engines for 2009. The new regulations in Japan require particulate emissions of one-third of what is currently allowed there, and one-fifth of what is currently allowed in Europe. Starting in the second half of 2008, Toyota intends to install their new engines in Europe, where forty percent o
