The H-engine—basically two separate engines housed within the same engine block—comprises two switchable parallel piston banks, independently fueled by gasoline and CNG. Startup Eco-Motive has developed what it calls the first dual-fuel “H” engine; it recently received a patent (# 8807098 ) on the design.
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. The program is focused on fuel economy improvement while achieving Euro IV emissions level. Click to enlarge. Earlier post.).
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.
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.
The family of engines strategy uses a common power cylinder system across several different engine variants to address a range of power and torque requirements in order to serve multiple military vehicles with a common architecture.
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.
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. —Musu et al., SAE 2010-01-2107.
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).
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. To further reduce fuel consumption, the eCity Truck platform can also integrate 48-volt technology. Control unit.
The latest version, the X4V2, was designed as a development engine for the aviation industry, and in early 2008 it was independently tested by Orbital Australia. tested the engine under the standard air/fuel ratio of 14.5:1 1 and also at our desired air/fuel ratio of 15.2:1 The engine. 1 of 238g/kW-h (34.4%).
A consortium led by micro gas turbine company Bladon Jets recently secured investment from the UK Technology Strategy Board to develop an Ultra Lightweight Range Extender (ULRE) for next-generation electric vehicles.

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.
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. The DOE anticipates making awards that range from $350,000 to $4,500,000, with a 24- to 48-month project duration.
A Romanian team—Dan Scarlat (automotive journalist), Marian Cilibeanu (designer) and Cristian Ionescu (engineer)—are proposing the SCI hyMod modular concept car. For longer-range interurban travels, it can transform into a hybrid car with the assistance of a special change center (“hyMod STATION”).
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%
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. This next phase of the program aims to take us closer towards that end objective.
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 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, 4-cylinder engine, the dual piston mechanism was able to adjust the engine from a CR of 9.6 Combining the high compression ratio with the Atkinson cycle, the engineering team demonstrated a 7.4% improvement in fuel economy in operation over the Japanese 10-15 cycle. and back again. Ishikawa, K. Yamamoto, M.
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. Schechter, M.
China’s fourth largest car manufacturer Chongqing Changan Automobile Co and Orbital Corporation Limited have formed a joint development to work on a conceptengine. It is hoped that with fuel economy improvements, the Euro IV emission levels will be achieved.
Ilmor Engineering will present a new cutaway version of the Ilmor five-stroke conceptengine at the show. Ilmor, based in the UK, has traditionally focused on racing engines, but now as a member of the UK Low Carbon Vehicle Partnership its business is becoming increasingly diverse.
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.
This technology will allow researchers to develop future combustion engines free from the piston motion constraints dictated by the crankshaft. Already validated at proof-of-concept level, Libertine’s new hardware uses production-feasible component designs suitable for automotive hybrid powertrain modules, such as range extenders.
