Swiss Federal Laboratories for Materials Science and Technology (EMPA) scientists have developed an innovative, electrohydraulically actuated valve train for internal combustion engines, that enables completely free adjustment of stroke and timing, while at the same time being robust and cost effective. This valve train was mounted on a serial production engine and has been running […]

Truck fuel consumption could be reduced by billions of gallons a year through the use of drag-reducing devices on semi tractor trailer trucks. According to new study presented at the American Physical Society’s Division of Fluid Dynamics (DFD) meeting in San Francisco the U.S. national truck fleet of more than 2 million tractor-trailer trucks that […]

The “Trailer 2011” show in Belgium features an aerodynamic trailer by Mercedes Benz that offers a reduction in wind resistance by up to 18%, with an accompanying decrease in fuel consumption by almost 5%.  In the U.S alone that’s a big part of a million barrels a day of crude oil not used. And it’s […]
