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

Can Dan Gurney’s Moment-Cancelling engine breathe new life into internal combustion?

American car racing legend Dan Gurney's patented Moment-Cancelling Four-Stroke (MC4S) engine features two counter-rotating crankshafts and an innovative intake system. With it, Gurney is looking to conquer the Holy Grail of internal combustion engines: reliability, efficiency and low emissions, all in a single design targeted at motorcycles, but which could also be used in cars, planes and boats.

Wärtsilä's new 31 becomes the most efficient 4-stroke diesel engine in the world

Finnish engine manufacturer Wärtsilä must be a fascinating place to visit. The company manufactures some of the most mind-bendingly enormous marine diesel engines in the world, like the record-breaking, 89-foot high, 44-foot long, 110,000 horsepower RTA96-C we wrote about more than 10 years ago. Now, Wärtsilä has another entry in the Guinness Book of Records ... for the world's most efficient 4-stroke diesel engine.Read More

ESA successfully tests 3D printed thruster

The European Space Agency (ESA) has successfully test fired a 3D printed platinum alloy thruster combustion chamber and nozzle. The world first test is further evidence that the 3D printing approach is a viable one for the aerospace industry, with the potential to cut costs by streamlining production methods and adding a greater level of flexibility in terms of supply and demand construction.Read More

Retrofittable electric engine adds power and safety to light aircraft

Small, single-engine aircraft are the mainstay of recreational flying, and provide many hours of generally safe enjoyment for hundreds of thousands of enthusiasts worldwide. However, with only one engine on-board, they are also often only a small malfunction away from becoming a heavy, unpowered glider in dire need of somewhere to land. To help improve this situation, researchers at Universidad Carlos III de Madrid (UC3M) and AXTER Aerospace have created an auxiliary electric propulsion unit designed to be installed in conventionally-powered light aircraft to both increase available power and provide extra range in the event of an engine failure.Read More

Porsche working on variable-compression engine

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine and one of the holy grails of such development is the creation of a viable variable-compression-ratio system. Now Porsche is working on just such an engine, revealed in the form of a newly-published patent, which will be able to alter its compression ratio. Read More

GE announces first FAA approved 3D-printed engine part

We've only just begun to see the huge impact 3D-printing technology will have on manufacturing, and the aerospace industry is a prime example. Earlier this year we saw the first example of a 3D-printed jet engine, now GE has announced the first 3D-printed part certified by the US Federal Aviation Administration (FAA) for a commercial jet engine. The fist-sized T25 housing for a compressor inlet temperature sensor was fabricated by GE Aviation and will be retrofitted to over 400 GE90-94B jet engines on Boeing 777 aircraft.Read More
