An aluminum piston (left) and one of the new steel pistons (right)

In 1936, Mercedes-Benz became the first company in the world to launch a diesel passenger car – the 260D. Over the years, diesel automobiles became renowned for their efficiency and fuel economy. Now, the manufacturer is building on that success with the introduction of high-tech steel pistons.  Read More

The UCR NOx-Out device replaces the muffler on an existing gas mower

Gas-powered lawnmowers are notorious polluters. According to the US Environmental Protection Agency, running a new gas mower for one hour produces as much air pollution as would be generated by 11 typical automobiles being driven for the same amount of time. Switching to an electric or reel mower is certainly one option, but for those applications where it's gotta be gasoline, a team of engineering students from the University of California, Riverside are developing another: an attachment that they claim reduces noxious emissions by over 90 percent.  Read More

Researchers at Princeton University have converted CO2 into formic acid by using an electr...

Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid.  Read More

Ford's Lightweight Concept vehicle based on the Fusion weighs less than a Fiesta

At NAIAS in January, Ford showed the world its new lightweight F-150 truck, which slashed 700 lb (318 kg) from its predecessor's weight to improve handling and fuel economy. Now the automaker has taken the weight-saving techniques from the F-150 and applied them to a new Lightweight Concept vehicle based on a Ford Fusion sedan.  Read More

EcoCAR 3 tasks students with updating the iconic Chevrolet Camaro muscle car into a hybrid...

For the past 26 years, the US Department of Energy (DOE), in partnership with the North American auto industry, has sponsored Advanced Vehicle Technology Competitions (AVTCs) to provide the next generation of automotive engineers with a practical learning experience. The previous EcoCAR Challenge saw students convert and massage GM Malibus into super-efficient models, and this time for EcoCAR 3, teams are tasked with updating the iconic Chevrolet Camaro muscle car into a hybrid-electric vehicle.  Read More

New research by Sintef scientists has found that refrigeration technology may reduce cost ...

For years carbon capture and storage (CCS) has been considered a costly but necessary step in reducing emissions and protecting our environment. New research by Scandinavian research organization Sintef has found that refrigeration technology may reduce costs by up to 30 percent, increasing the potential for faster implementation.  Read More

The team observed reductions in emissions of NOx, particulate matter and greenhouse gases ...

The EPA has identified pollution from ships as a contributing factor to respiratory problems and premature deaths suffered by residents of the US and Canada. As such, it is in the process of implementing stricter emissions standards for ships operating within 200 miles (321.9 km) of shore with the aim of significantly reducing emissions by the year 2020. In a development that could play into these environmental initiatives, the SeaChange Group, a US-based start-up that converts agricultural by-products into clean-burning fuel, has been awarded a patent for an eco-hybrid fuel technology shown to reduce NOx, particulate matter and greenhouse gas emissions.  Read More

The Audi traffic light system uses icon prompts

One of life's small but satisfying pleasures is hitting the sweet spot while driving across town and catching all the green lights. At the moment, having that happen is a matter of luck, but Audi is developing a system that will make never getting caught by a red light an everyday thing as a way of speeding up traffic while improving fuel efficiency and cutting emissions.  Read More

Astrophoto in redshifted Lyman-alpha light, possibly emitted by a cosmic filament of gas a...

That the Universe is largely composed of a cosmic web consisting of narrow filaments upon which galaxies and intergalactic gas and dust are concentrated has been known for more than a decade. While a great deal of evidence for this has accumulated, visual evidence has been difficult to find. Astronomers have now photographed what appears to be a segment of a cosmic filament stimulated into fluorescence by irradiation from a nearby quasar.  Read More

Regular catalytic converters like this one may be on their way to obsolescence (Image: Shu...

By helping to minimize the hydrocarbons and other pollutants that are emitted in a car's exhaust, catalytic converters serve an important purpose. Because they contain precious metals such as platinum, however, they can also be expensive. Now, a British scientist has developed a new type of converter that should be cheaper, longer-lasting and more effective, plus it should boost the vehicle's fuel efficiency.  Read More
