Rendering of the Ilmor 5-stroke conceptengine. Ilmor Engineering will present a new cutaway version of the Ilmor 5-stroke conceptengine at the upcoming Engine EXPO 2009, 16-18 June, in Stuttgart, Germany. The 5-stroke conceptengine is a self-funded proof of concept. Click to enlarge.
The WDG also can reduce carbon dioxide emissions by as much as 95 percent in comparison to modern internal combustion vehicle engines. The Wave Disc Engine. The wave disc engine is a new implementation of wave rotor technology (also called Pressure Wave Machines or Pressure Exchangers). Norbert Müller. Click to enlarge.
Motiv said that the major components of the MkII Clarke-Brayton Engine have been released for casting and everything else should be released for fabrication within a couple of weeks. The company will test the engine this summer. The technology for the MkII Clarke-Brayton Engine originated at Caterpillar, Inc. Background.
The combination of discrete, asymmetrically sized cylinders and fully variable valvetrain promises the ability to vary displacement ratios, bore-stroke ratios, compression-expansion ratios, compression-expansion phasing, and gas transfer phasing for engine optimization—i.e., a more efficient internal combustion engine.
Mercedes-AMG and Cigarette Racing launched the latest development of their cooperation at the Miami International Boat Show (14-18 February 2013). Numerous components from the SLS AMG Coupé Electric Drive ( earlier post ) have been integrated in the design of the “Cigarette AMG Electric Drive Concept” engineering design.

The work was conducted by a collaboration including industrial partners Arup, Dearman EngineCompany, E4 Tech, Highview, Messer Group and Ricardo, as well as academics from the Universities of Leeds, Birmingham, Strathclyde, Brighton and Imperial College London.
Australia-based Revetec is designing what it calls the Controlled Combustion Engine (CCE)—a cam-drive gasoline spark-ignited internal combustion engine that is smaller, lighter, cleaner, less expensive to manufacture and that produces higher torque due to higher mechanical transfer than equivalent conventional engines.
A collaboration between research teams at Shell and Gordon Murray Design (GMD) recently led to the development of an innovative conceptengine lubricant capable of achieving a 6.5% 25 city car as the test bed, Shell engineers formulated an ultra low viscosity 0W-10 motor oil. benefit on a combined cycle. Using GMD’s new T.25
liter engine that is 17 inches in diameter with a length of 13 inches and a total weight of 200 pounds (91 kg) in normally aspirated form. The compact engine weighs 75% less than and is half the size of traditional internal combustion engines. The power electronics is the last mile of the OX2 engine/generator development.
Internal cooling with air or water (Rankine). Using a model calibrated to the data from the engine, LPI has shown that if it achieve sealing, heat transfer coefficients, and friction similar to today’s Mazda Wankel engine, it can achieve its efficiency goals. Constant volume combustion (Otto).
The LowCVP Technology Challenge is supported by the Institution of Mechanical Engineers (IMechE) and with an associated media partner, Cleantech Investor. Market access and investment funding are key barriers for automotive technology companies. Rotor 1, Rotor 2 and the connecting cam form the total internal mechanism of the engine.
The new ECONAMIQ technology builds on existing concepts such as cylinder deactivation and variable valve timing with a unique patented combination of routing gasses for increased system efficiency. The company presented its first results at the annual ASME ICEF (Internal Combustion Engine Fall) conference in Chicago.
China’s fourth largest car manufacturer Chongqing Changan Automobile Co and Orbital Corporation Limited have formed a joint development to work on a conceptengine. If it proves successful, Changan hopes to take the FlexDI concept to mass production. It is not the first time that the two companies have joined forces.
Petersburg, Florida for engineering, drafting, design and manufacturing management functions for prototype development and production. The project will take the Garric design from its current advanced concept stage to development of a fully functional prototype, according to the company.
The one-liter, naturally-aspirated gasoline prototype is expected to produce up to 80% fewer criteria pollutants than a typical internal combustion engine. When fully developed with its turbocharged and air-hybrid components, the engine is expected to achieve significant gains in fuel efficiency. Sal Scuderi. 52: power side.48:
