Magnesium alloys are very attractive for a range of weight-sensitive applications. They have the largest strength-to-weight ratio of the common structural metals, are lighter than aluminum and are particularly favored for being easy to machine and for their ability to be die cast to net shape. Unfortunately, magnesium alloys tend to corrode too easily. A team at Monash University in Australia has now discovered a novel and potentially game-changing approach to the problem: poisoning the chemical reactions leading to corrosion of magnesium alloys by adding a dash of arsenic to the recipe.  Read More

3D printing technology has already made the move from engineering workshop to the home, and now it's set to make its mark in space. NASA has hot-fire tested 3D-printed rocket engine components, which have managed to withstand incredibly high temperatures and pressures to the same standard as traditionally manufactured parts. Being cheaper and faster to produce, 3D-printed parts have the potential to revolutionize the manufacturing of rocket engine components and save the space agency considerable time and money.  Read More

Delphi's single cylinder Gasoline Direct Injection Compression Ignition (Photo: Delphi)

With both gasoline and diesel engines having their own particular advantages and disadvantages, automotive component manufacturer Delphi is looking for a best-of-both-worlds solution with a gasoline-powered engine that uses diesel engine-like technology for increased fuel efficiency. According to MIT’s Technology Review, such an engine has the potential to increase the fuel economy of gasoline-powered cars by 50 percent and give hybrid vehicles a run for their money in the fuel economy stakes.  Read More

Teaser photos and video: the 2011 Kawasaki Ninja ZX-10R

Here it is – the new ZX-10R. The bike that lured MotoGP race-winner Chris Vermeulen into the worst team in the WSBK paddock; the bike that both Vermeulen and Kawasaki believe will put Kawasaki back at the front of the Superbike grid. All we have at this stage is a few photos of the race Superbike version and a teaser video, but expectation has been building that the new Ninja could be the first Japanese bike to take it to the amazing new BMW S1000RR. Numbers like 200 brake horsepower and a wet weight under 200kg have been floating around for the streetbike version. We know that there's going to be some form of traction control, which puts the Kwaka into a small but growing class of sports machines, and most interestingly, patents have been spotted that indicate that Kawasaki is thinking about running a proper long-bang style engine configuration, complete with an additional electric motor to keep the crank spinning in between pulses at lower speeds. Certainly, upon its release this will be Kawasaki's most significant motorcycle in many years.  Read More

The Revenge Verde supercar that offers a fuel efficient HP2g engine

The Revenge Verde is an American-made supercar using “the best of the best” parts sourced from a range of supercar manufacturers. The mid-engined Verde offers three drive chain and power train options, including an HP2g V8 engine that runs on E-85 ethanol fuel and produces 400hp, goes from 0-60mph in 3.5 seconds with a top speed of 200mph+, while achieving an amazing 100mpg. We had a chance to chat with Peter Collorafi, the CEO/President of Revenge Design Inc, as well as Doug Pelmear, CEO of HP2g to find out more about the car's development. Check out in our video after the jump.  Read More

Bladon Jets high efficiency micro gas turbine engine

The UK government-backed Technology Strategy Board recently announced the recipients of carbon reduction technology research project funding which sees a consortium made up of Jaguar Land Rover, SR Drives and led by Bladon Jets taking a GBP 1,103,392 (about US$1,790,000) slice of the multi-million GB-pound cake to develop "the world’s first commercially viable - and environmentally friendly - gas turbine generator designed specifically for automotive applications."  Read More

Honda's Personal-Neo Urban Transport ultra-compact vehicle - or P-NUT for short

With the variety of different engine technologies emerging to replace the traditional internal combustion engine, Honda has taken a very smart approach with its Personal-Neo Urban Transport (P-NUT) ultra-compact vehicle. The concept car features a modular rear engine bay designed to accommodate a wide variety of potential powertrain technologies including a conventional small internal combustion engine, a hybrid system, or a battery-electric drivetrain.  Read More

The most fuel-efficient diesel engine in the world, the Wärtsilä RTA96C, converts 50% of f...

The two engine technologies tend to be regarded as completely separate, so we rarely contemplate how gasoline and diesel can work together. But, in a series of tests conducted at the University of Wisconsin, scientists have used an engine’s fuel injection to produce the optimal diesel-gas mix for any given moment. The results are impressive: an average 20% greater fuel efficiency; combustion temperatures reduced by up to 40%; and effortless meeting of the stringent EPA 2010 emission regulations. Plus, the researchers believe that if their findings were implemented into every gasoline and diesel engine in the US, the savings could be as great as 4 million barrels of oil daily.  Read More

The Chevy Volt - a flagship American electric car that's sure to benefit from Obama's reco...

Awesome news: battery technology is about to get a US$2.4 billion-dollar kick in the pants. US President Barack Obama has announced the single largest funds injection into battery development and electric/hybrid vehicle technology the world has ever seen. Obama's hope is that this huge chunk of stimulus funds will be enough to knock down the biggest wall standing between electric vehicles and the mainstream: the fact that current batteries are still too expensive, take too long to charge, and don't hold enough energy. If the move succeeds, it could put America right at the front of the electric car revolution - but at the least, it could help the next generation of iPhones last more than a day between charges.  Read More

The International DuraStar at the Hybrid Truck Users Forum in South Bend, Ind.

With the spiraling cost of fuel and the average cost of diesel in 2008 climbing around 39 percent versus last year, it’s no surprise that truck manufacturers are looking to lighten the burden on trucking operators. To this end Navistar, makers of the LoneStar, has expanded its line of diesel electric hybrid trucks with the unveiling of their International DuraStar Hybrid tractor at this week’s Hybrid Truck Users Forum in South Bend, Indiana. Navistar claims that the new diesel electric hybrid Class 7 tractor has the proven capability to provide fuel savings of 20-25 percent on standard in-city pickup and delivery applications.  Read More
