Fuel efficiency

In order to achieve significant improvements in thermal efficiency, the Atkinson Cycle eng...

Toyota has announced the development of two hyper-fuel-efficient small-displacement petrol Atkinson cycle engines: a three-cylinder 1.0-liter and four-cylinder 1.3-liter which will be introduced across the range from next year in 14 different variations. The smaller engine will deliver 78 mpg (US) in the Toyota Aygo, an improvement of 30 percent.  Read More

If you think that you've been seeing some funny-looking airliners in the past couple of months, you're not imagining things. On February 18th, a United Airlines Boeing 737-800 made the world's first commercial flight by an aircraft equipped with fuel-saving Split Scimitar Winglets.  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

The front-wheel-drive pocket rocket market is likely to become all four-wheel-drive in the...

If you were compiling a list of the world’s sportiest front wheel drive cars, you’d no doubt start with names like the MINI Cooper S, Volkswagen Golf GTI or Scirocco R, Ford Focus RS500 or Taurus SHO, Honda Integra Type R, Vauxhall/Opel Vectra or Astra VXR models, Peugeot 205 GTi, Alfa Romeo 147 or 156 GTA models, Nissan Altima Coupe, Mazda speed3, one of the Renaultsport Meganes, or if you’re a little older perhaps the Lotus Elan, Lancia Fulvia, Fiat Abarth or Volvo S80 T6. Now there’s a new name to put at the very top of that list and several new contenders gunning for the crown.  Read More

The Walmart Advanced Vehicle Experience, on the road

According to a report in Truck News, Walmart plans on doubling the fuel efficiency of its trucking fleet by next year. In order to show that it's not kidding around, the retailer has collaborated with Peterbilt, Great Dane Trailers, and Capstone Turbine to create a concept "truck of tomorrow" known as the Walmart Advanced Vehicle Experience – or WAVE.  Read More

The unit will fit inside a shipping container, and could be towed around the port on a bar...

Shipping ports are major sources of air and water pollution, due in part to anchored or docked ships using diesel generators to keep their onboard systems powered up. A year from now, however, the Port of Honolulu will be trying out a mobile hydrogen fuel cell unit, as a more eco-friendly and fuel-saving alternative.  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

FlexSys' variable geometry airfoil, the FlexFoil

If there's one thing that needs to be aerodynamic, it's an airplane wing. Conventional wing designs however, suffer from a glaring weakness in this respect: the joint where the main wing meets the trailing flaps. Michigan-based FlexSys has developed a way to optimize wing aerodynamics with FlexFoil, a seamless variable geometry airfoil system that could deliver fuel savings of up to 12 percent.  Read More

Bosch's new system is intended to reduce fuel consumption and CO2 emissions

Cars don't need to have their engines running when they're stopped at red lights. That's why a number of automakers have developed start-stop systems, which stop a car's engine when the vehicle comes to a halt, and start it again as soon as the gas pedal is pressed. Bosch, however, is taking things farther. Its new start-stop system shuts the engine off not only at stops, but also whenever the car is coasting.  Read More
