"World’s smallest engine" to power microscopic robots

It is often said that size matters. At the nano-scale level, where a lot of current research is being done, this adage also holds true, and several scientific teams have laid claim to creating the "world's smallest engine" built from particles of ever-shrinking dimensions. The latest, a nano-scale engine made from tiny charged particles of gold and developed by researchers at the University of Cambridge, is claimed to be the smallest of them all.Read More

Volkswagen turns to the Miller Cycle for improved efficiency

Manufacturers are leaving no stone unturned in the quest to improve the efficiency of their internal combustion engines. Just this week, we've seen a fastidiously engineered diesel engine from Ford and a camless engine from Qoros. Now Volkswagen, no stranger to doing whatever it takes to lower consumption (figures), has joined the party by releasing a 1.5-liter Miller Cycle engine tasked with improving fuel consumption and increasing low-down torque.

World's largest commercial aircraft engine fired up for the first time

The world's largest commercial aircraft engine has been started up for the first time at GE Aviation's Peebles Test Operation in Ohio. According to GE, ground testing of the GE9X development engine will enable data to be gathered on the engine's overall and aerodynamic performance, mechanical verification, and aero-thermal system validation leading up to flight testing and certification before entering service at the end the decade.Read More

World's smallest engine powered by a single atom

A team of German physicists has just created the world's smallest working engine. Powered by a single electrically-charged calcium atom, the new device is claimed to have the equivalent thermodynamic efficiency (if scaled to size) of an average automobile engine. Basically a heat-exchange engine, its single-atom acts as both fuel and powerplant and is heated by electrical noise and cooled by laser beam.Read More

Tractor Heaven: 240 acre private park showcases vintage engines, tractors and the fine art of digging a really big hole

Labor saving devices are nothing new, but they rarely inspire the kind of dedicated stewardship that antique engines do. This week in Fort Meade, Florida, the 1500 members of the Florida Flywheelers Antique Engine Club opened the gates of their unique 240-acre clubhouse to give the public a first hand look at the fruits of this devotion. If you harbor a secret wish to operate a tractor, bulldozer or backhoe, these are your people.Read More

Ford using plasma to refurbish dead engines

When an engine fails or becomes very worn, it is usually pulled from the vehicle and scrapped. Ford wants to change that by utilizing a high-tech plasma process to remanufacture broken engines. The process reduces carbon emissions by about half when compared to making a new engine to replace the old one, and results in a like-new engine block.Read More

Spirit Charger Concept SC 01 portends the future of Kawasaki's H2 and H2R motorcycle line

Kawasaki gave us a potential glimpse of the future of it's supercharged product line-up at the Tokyo Motor Show when President Kenji Tomida showed a sketch of Concept SC 01 (SC stands for “Spirit Charger”), which uses softer lines and more luxurious materials than the hard-edged and spartan styling of the 200 hp Ninja H2 and 300 hp H2R. At the same time, Kawasaki showed a newly-developed version of it's supercharged engine which uses electronically-controlled flaps at the supercharger entrance aimed at increasing efficiency and fuel economy.Read More
