Thermochemical exhaust heat recuperation (TCR) in an internal combustion engine could result in substantial boosts in second-law efficiency (as measured in terms of single-stage work output from an ideal IC engine) for a range of fuels, according to a new study by researchers at Oak Ridge National Laboratory (ORNL).
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. Hîrceagã, M.,
A split-cycle engine is essentially an air compressor on one side with a combustion chamber on the other. The Scuderi engine is expected to produce up to 80% fewer toxins than a typical internal combustion engine. The Scuderi Engine. Tags: ConceptEnginesEngines. Source: Scuderi.
An OEM can adopt our idea to any internal combustion engine with an even number of cylinders to any truck, SUV or car they currently build, regardless of its transmission or configuration. The technology can be easily adapted to existing engines, making the implementation very cost effective.

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 detailed animation of the cycle is available on the Garric Engine website. Company whitepaper: Inside the Non-Reciprocating, Variable Compression Internal Combustion Engine. Tags: ConceptEnginesEngines.
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.
A cryogenic engine such as the Dearman engine could also be used as a heat hybrid in combination with an internal combustion engine or hydrogen fuel cell to convert waste heat into additional shaft power at high levels of efficiency, reducing both fuel consumption and emissions. High efficiency internal combustion engine.
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
Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change.
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.
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. Tags: ConceptEngines. The current OX2 is a 4-stroke, 1.1-liter
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.
Powertrain concepts. At NACV 2017, Bosch is also showcasing several future-focused powertrain conceptsengineered to save fuel and money while extending the lives of fleets. The design calls for a scalable battery that makes an all-electric driving range feasible, enabling zero local emissions driving in city centers.
Internal cooling with air or water (Rankine). HEHC is an improved thermodynamic cycle optimized for fuel efficiency that combines features of four existing cycles: High air compression ratio (Diesel). Constant volume combustion (Otto). Over-expansion to atmospheric pressure (Atkinson).
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.
Induction air enters at the center of the engine and compression/expansion occurs at the periphery producing uniform heat flow characteristics as air circulates around the two sides of the engine. Rotor 1, Rotor 2 and the connecting cam form the total internal mechanism of the engine. Overview of the Libralato Engine.
The New York International Auto Show saw Mazda showcase a series of new engine and transmission concepts that improve fuel efficiency and lower emissions. Known as the SKY Conceptengines and transmissions, they will be rolled out from 2011.
