A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. Combustor Compressor. Displacement.
The component materials must be capable of being manufactured at a lower cost and with a smaller environmental footprint when compared to present technologies. Increased efficiency may be achieved using one or more proposed enabling technologies on a baseline engine. turbomachinery. turbomachinery.
This is a major step toward our goal of building the most efficient engine in the world for trucks, automobiles and power generation. The improvement in efficiency and the use of natural gas makes this engine a natural fit to meet the upcoming greenhouse gas emissions regulations while reducing costs for operators. Graves, R.
Achates Power, which is developing a family of two-stroke, compression-ignition (CI) opposed-piston (OP) engines, has designed and is developing a light-duty diesel conceptengine, the OP4. liter OM651 Euro 5 engine, said Fabien Redon VP, Technology Development at Achates Power, the OP4 design shows a modeled 13.5%
The extremely low flammability limit of hydrogen can also be used to extend the lean combustion limit, which can increase expansion work and reduce emissions. TCR is particularly relevant to alcohol-based engine fuels, because combustion exergy losses for direct combustion of alcohols are typically higher than for alkanes and alkenes.
The UK Centre for Low Carbon Futures published a multi-partner research report— Liquid Air in the energy and transport systems: Opportunities for industry and innovation in the UK —and presented the results at a a conference at the Royal Academy of Engineering in London. High efficiency internal combustion engine.
(LPI), the developer of engines based on its High Efficiency Hybrid Cycle (HEHC)( earlier post ), introduced the latest version of its X-series of rotary engines embodying HEHC at the US Department of Energy’s (DOE) 2012 Directions in Engine-Efficiency and Emissions Research (DEER) Conference in Dearborn, Michigan.
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.
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. At NACV, Bosch will present progress to-date on the project as part of a comprehensive view of the future of the commercial vehicle powertrain.
