The ChangAn CA18 FlexDI ConceptEngine shown at Auto China 2008. Ltd, China’s fourth largest automotive manufacturer, have entered into a joint development contract for a conceptengine. If the program is successful, Changan plans to take the FlexDI conceptengine to mass production in a Changan vehicle.
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.
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).
Our goal is to enable hyper-efficient hybrid vehicles to meet consumer needs for a 500-mile driving range, lower vehicle prices, full-size utility, improved highway performance and very low operating costs. The WDG also can reduce carbon dioxide emissions by as much as 95 percent in comparison to modern internal combustion vehicle engines.
The engine was invented by Herns Louis, veteran of more than 30 years in the parts manufacturing industry ranging from automotive to aerospace, specializing in computerized parts machining. The technology can be easily adapted to existing engines, making the implementation very cost effective.
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.
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.
It potentially is attractive for use in small cars and vans for short range urban use, scooters, short range marine craft, forklift trucks and mining equipment. High efficiency internal combustion engine. Compressed air engines (e.g., Compressed Air EnginesConceptEnginesEngines'
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.
The OX2 engine achieves considerable torque at all stages through its operating range. Consequently, in most engine applications there would be no need for the engine to operate at revs higher than 2,500 rpm. In some instances, this would eliminate the need for a gearbox and would certainly reduce engine wear.
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.
The Vehicle Technologies funding is targeted at a wide range of research, development, and demonstration projects that aim to reduce the price and improve the efficiency of plug-in electric, alternative fuel, and conventional vehicles. CFD software is used by all internal combustion engine developers in the automotive and related industries.
Researchers at the Dalian University of Technology have proposed a novel method to control premixed charge compression ignition (PCCI) phasing in internal combustion engines in all load operations. The utilization of compressed air power on engine cool starts and low-load conditions could significantly reduce the overall emissions. …
China’s fourth largest car manufacturer Chongqing Changan Automobile Co and Orbital Corporation Limited have formed a joint development to work on a conceptengine. In April 2008, Changan displayed a prototype engine developed with Orbital at the Beijing International Motor Show.
