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-fueledengines. HCPC Combustor and Compressor.
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 engine is designed for use in light-duty vehicles, and demonstrates the potential of modifying passenger vehicle engines to achieve diesel-like fuel efficiency and power using CNG as an alternative fuel. This engine demonstrates a potential near-term solution. —Gary Rogers, FEV, Inc. president and CEO.
Compared to the fourth-generation M5 power unit, the newly developed engine has a significantly increased output level, while at the same time lowering previous fuel consumption and emission levels by at least 25%.
Drive-E Powertrain Concept. Volvo has developed a concept 2-liter, 4-cylinder, triple-boost Drive-E conceptengine that delivers 450 hp (336 kW). The 450 hp High Performance Drive-E Powertrain Concept is based on a set of technologies not usually found in a four-cylinder engine. Dual fuel pump.
Ballard Power Systems and MAHLE Group, a Tier 1 automotive supplier, are progressing the development of a new fuel cell system concept for long-haul trucks, with MAHLE taking delivery of a 120kW module at the company’s hydrogen test center in Stuttgart, Germany. Fuel efficiency is also key for a manageable heat rejection system.
OCI) and MAN Energy Solutions (MAN) to develop methanol and ammonia as marine fuels to support industry-wide decarbonization and environmental preservation efforts. Also, EPS will construct newbuild vessels with MAN engines powered by the same two alternative marine fuels.
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% improvement in fuel efficiency on an urban cycle, and a 4.6% benefit on a combined cycle. Using GMD’s new T.25
million from the Department of Energy’s ARPA-E program ( earlier post ) to complete its prototype development of a new gasoline-fueled wave disc engine and electricity generator that promises to be five times more efficient than traditional auto engines in electricity production, 20% lighter, and 30% cheaper to manufacture.
When reforming is not used, the fuel and exhaust pass through CV2 unchanged. A paper on their work was published online 5 February in the ACS journal Energy & Fuels. The basic concept of TCR involves using exhaust heat to promote on-board reforming of hydrocarbon fuels into syngas (a mixture of carbon monoxide and hydrogen).
Motiv Engines, LLC introduced the second-generation of its engineconcept dubbed the MkII Clarke-Brayton Engine, which it intends to develop into a heavy-duty on-highway enginefueled by liquid natural gas (LNG). Berlinger, “A New Compression Ignition EngineConcept for High Power Density,” pp.
Researchers at ETH Zürich, with partners Robert Bosch GmbH, Wenko Swissauto and the Swiss Federal Office of Energy are developing a downsized and supercharged hybrid pneumatic engine that they say can deliver a fuel consumption reduction of more than 30% compared to a standard engine with the same rated power. Earlier post.).
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%
In its chapter, Ricardo considered a number of potential roles for liquid air considered in which the air is used as a heat sink and then as a working fluid within a heat engine. The heat engine can be deployed as either the prime mover or in a supporting role to recover waste heat from a conventional engine or fuel cell.
DOE also announced up to $35 million to advance fuel cell and hydrogen technologies, including enabling the early adoption of fuel cell applications, such as light duty fuel cell electric vehicles. Increased efficiency may be achieved using one or more proposed enabling technologies on a baseline engine. turbomachinery.
Dutch start-up ECONAMIQ is developing a novel engine technology which saves up to 20% in fuel consumption. The “ECONAMIQ principle” uses flexible over-expansion in combination with cylinder deactivation technology to increase performance and efficiency without significantly changing the engine layout or architecture.
Bladon suggests that in an hybrid vehicle application, with no water-cooling system, oil or catalytic converter, the Micro-Jet engine can provide vehicle weight savings of up to 15%—with a consequent reduction in fuel consumption and carbon emissions—compared to a piston engine. Earlier post.).
HCCI is a combustion regime in which well-mixed fuel, exhaust gas and air are compressed to the point of auto-ignition. Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber. Ignition occurs via the sparkplugs.
When we launched our HDV efficiency program we stated a belief that HDV carbon dioxide emissions could be reduced by up to one-third. Vehicle fuel efficiency could be increased by 2 to 5% if lower drivetrain losses could be effectively halved which means this project has the potential to make a beneficial step change to the HDV industry.
The first registrant in the Challenge is Libralato Engines, developer of a novel rotary engine (cutaway shown) promising a 5.5% gain in combustion efficiency and 50% reduction in NO x emissions. In the second compression phase, the air is compressed at a higher compression ratio where the fuel is added. Click to enlarge.
(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 prototype is of the naturally-aspirated Split Cycle gasoline engine, and is intended to be a proof of the basic technology of the split cycle with firing after Top Dead Center (one of the key attributes of the engine and cycle). As a result, Scuderi said, combustion is four times faster than in a conventional engine.
The engine can be adapted to run any combustible gas or liquid as fuel. Advanced Engine Technologies was incorporated in 1996 to commercialize the OX2, with automotive racing pioneer Carroll Shelby on its Board of Directors and involved in the engine development.

The engine components are contained within a sphere. The first cycle is a “conventional” combustion engine process using a combustible fuel with the crankless (i.e., Fuel and air are compressed, then combusted. Any combustible fuel can work in the Reinhardt Turbine, the limiting factor is emissions control.
High-pressure air jet controlled compression ignition (JCCI) is based on a compound thermodynamic cycle and is implemented in a hybrid pneumatic engine (HPE) as proposed by Schechter in 1999. The application of HPE is also beneficial to the fuel consumption and emissions because of its several flexible operation modes.
