Fraunhofer's cylinder bore hole honing tool

You may think that the pistons in your car’s engine slide in and out of the cylinder bore holes smooth as silk, but according to researchers from Germany’s Fraunhofer Institute for Machine Tools and Forming Technology, the process could be smoother. If it was, your car would burn less gasoline, and require less oil for lubrication. Well, those researchers have developed an engine-building tool, designed to minimize engine cylinder friction.  Read More

The Conley Stinger 609 supercharged four-cycle V8 gasoline engine - 6.09 cubic inches and ...

Giant-scale model cars (and airplanes) powered by small gasoline engines have been popular with adult racers for quite a few years now. The largest scale models available through conventional RC hobby outlets are one-fifth or one-sixth scale, but the serious racers go quarter-scale. Now the smallest (quarter-scale) blown V8 gasoline engine in commercial production is being turned out by Conley Precision Engines to power.  Read More

SABRE is a crucial part of Reaction Engine's plans for the SKYLON spaceplane

Reaction Engines has announced that is has successfully tested the key pre-cooler component of its revolutionary SABRE engine crucial to the development of its SKYLON spaceplane. The company claims that craft equipped with SABRE engines will be able to fly to any destination on Earth in under 4 hours, or travel directly into space.  Read More

Rolls-Royce's LEGO jet engine is made from 152,455 standard LEGO bricks and parts (Photo: ...

Rolls-Royce this week unveiled the world's first jet engine to be made entirely out of LEGO bricks. Farnborough Airshow was the selected venue for the unveiling of the model, which is made entirely from 152,455 standard LEGO bricks and parts, making it, Rolls-Royce claims, "one of the most complex LEGO structures ever built." The LEGO engine is a half-size replica (complete with moving parts) of the Rolls-Royce Trent 1000 turbofan jet engine which keeps Boeing's 787 Dreamliner in the sky. Naturally, we at Gizmag jumped at the opportunity to stick our noses (and camera lenses) in.  Read More

The 'noise sponge' that can significantly reduce the noise of combustion in jet engines (P...

Anyone living near an airport will tell you that combustion engines can be pretty noisy things. The combustion process in jet and other industrial engines can generate sound waves so powerful they can cause intense pulsations that can shake the engine and accelerate mechanical failure. Using a sponge-like material, researchers at the University of Alabama have managed to significantly quiet combustion at the source, providing the potential to make work environments safer, extend the life of valuable equipment, and maybe let those living near an airport sleep a little easier.  Read More

This vintage 30-ton 1600-horsepower Type 9 V.O.S. Duvant engine is currently on display at...

Hey, you like really big engines? Well, here’s one that’s not going to fit under the hood of your F-150. This 30-ton (27-tonne) Type 9 V.O.S. engine is one of just three built by the French company Duvant in 1962. It’s over 18 feet (5.5 meters) long, 11 feet (3.4 m) tall, and gulps down 350 liters (92.5 US gallons) of diesel fuel per hour. With its four valves per cylinder and turbocompressor, it is capable of producing 1600 horsepower. Best of all, should you happen to be in Paris this week, you can see the thing running.  Read More

The Bentley V-8 will be available this spring

Bentley has introduced its long-awaited V-8 engine developed in conjunction with Audi. The V-8 will give Bentley owners a smaller, more economical alternative to the more traditional W-12.  Read More

 Principle of the microscopic engine (Diagram: University of Stuttgart)

It sounds implausible, yet scientists have managed to create a functioning engine, analogous to a Stirling engine, just three micrometers wide and made of a single particle. The minuscule engine was created by Clemens Bechinger and Valentin Blickle at the University of Stuttgart, and though it has its quirks, the pair have apparently demonstrated the engine's ability to do work.  Read More

Patelo inserts a tiny piston into his miniature V12 engine

Anyone who appreciates the precision art of engine design ought to get a kick out of this offering from a Spanish engineer named Patelo. Starting with hunks of aluminum, bronze and stainless steel, he spent over 1200 hours designing, milling, turning and drilling what he claims is "probably" the world's smallest V12 engine. Powered by compressed air injection (0.1kg/sq cm), this little marvel boasts a total displacement of 12 cubic centimeters from its twelve 11.3 mm diameter pistons and works like a charm. Best of all, you can see it come together in the detailed video that follows.  Read More

The heart of the wave generator motor

The mid-term future for fuel efficient vehicles with useful range is likely a hybrid solution of electric motors powered by batteries, topped up by a fuel-burning generator. Prof. Norbert Müller at Michigan State, backed by $2.5 million from the US Government, aims to make that last part of the equation a much more compact and efficient proposition with a revolutionary new form of combustion engine.  Read More
