Working with colleagues from Deakin University and CSIRO (Commonwealth Scientific and Industrial Research Organisation), researchers from Australia's Monash University have created the world's first 3D-printed jet engine. While they were at it, they created the world's second one, too. One of them is currently on display at the International Air Show in Avalon, Australia, while the other can be seen at the headquarters of French aerospace company Microturbo, in Toulouse.  Read More

Inside the 9HA Harriet gas turbine

One of the problems with building the world's largest and most powerful gas turbine is that you need to build a test bed to match. Having invested US$1 billion in its 500,000 bhp 9HA Harriet gas turbine, GE had to fork over another US$185 million to build a full-load test bed at GE Power & Water in Greenville, South Carolina that can handle the grid-busting output of Harriet.  Read More

All variants of the new motor should meet the tough Euro 7 emissions standards

Volvo continues to chase better fuel economy with the development of a new three-cylinder engine, which will sit alongside the Swedish brand's Drive-E four-cylinder motors in its lineup.  Read More

Two views of the X Mini

Back in 2012, Gizmag looked at LiquidPiston’s X2 rotary engine. The compact, low-vibration, high-efficiency 70 bhp and 40 bhp compression ignition engine was something of a sensation. Now the company is back with the 70 cc X Mini engine, which LiquidPiston’s President and Co-Founder, Dr Alexander Shkolnik unveiled on Wednesday at the SAE International/JSAE 2014 Small Engine Technology Conference in Pisa, Italy.  Read More

Initially designed for as an electrical generator, Namikoshi realized that its 4-in-1 engi...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering marvel, there remain many friction points that reduce energy output. Namikoshi Electronics of Japan believes its unorthodox 4-in-1 concept engine could provide an alternative powerplant to the automobile industry.  Read More

The high powered engine is also designed to improve weight distribution between the front ...

The unveiling of a new four-banger engine wouldn’t normally garner much attention, but Volvo's High Performance Drive-E Powertrain Concept is an exception. The 2.0 liter, gas-powered unit features "triple boost" technology capable of generating no less than 450 hp.  Read More

The Duke Axial Engine is lighter, more compact and already slightly more powerful than a t...

New Zealand's Duke Engines has been busy developing and demonstrating excellent results with a bizarre prototype axial engine that completely does away with valves, while delivering excellent power and torque from an engine much smaller, lighter and simpler than the existing technology. We spoke with Duke co-founder John Garvey to find out how the Duke Axial Engine project is going.  Read More

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

Prof. Rolf Reitz (center) and members of his student team with the RCCI-powered Saturn

Five years ago we first heard about a Caterpillar diesel engine located at the University of Wisconsin-Madison, that had been modified to run on an unlikely-sounding mixture of diesel and gasoline. Not only did the one-cylinder engine work, but it was more efficient than pure-diesel or pure-gas engines at converting the chemical energy of fuel into motion. Sitting in a basement lab, however, isn't the same as experiencing use in the real world. That's why students at UW-Madison, led by Prof. Rolf Reitz, have now put another diesel/gas engine into a 2009 Saturn.  Read More

The new Volvo XC90's hybrid drivetrain

We've seen the interior of the new Volvo XC90, and we have an idea of its shape, but until now there has been no word on what would be under the hood. Volvo has now released details of the engines that will power its new SUV.  Read More
