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. Orbital was selected as the technology with the best potential to meet the aggressive targets required for the program.
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.
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. This new funding opportunity announcement will be available in early February. Reducing the cost of electric drive systems from $30/kW to $8/kW.
FEV) a leading developer of advanced powertrain and vehicle technologies, will exhibit a lean burn engineconcept at the SAE 2011 World Congress that has been modified to run on Compressed Natural Gas (CNG). FEV Inc., (FEV)
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.
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.
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.
Honda R&D began developing the VCR mechanism due to what Masahsi Kato, who presented a paper on the control system of the dual piston mechanism, described as drawbacks to current approaches to improving fuel-efficiency in gasolineengines of downsizing and new combustion technology. Kadota et al. Ishikawa, K. Yamamoto, M.
The conceptengine uses the Bosch electro-hydraulic valve system (EHVS). The engine has two intake and two exhaust valves per cylinder. The team was able to test all conventional and pneumatic engine modes on the conceptengine. The team replaced one exhaust valve per cylinder with a charge valve.
The prototype is of the naturally-aspirated Split Cycle gasolineengine, 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). The company intends to license its technology to engine manufacturers.
Rendering of the Grail Engine. Grail EngineTechnologies , the designer of a two-stroke engine using forced semi-homogeneous charged compression ignition (FS-HCCI) combustion, has adopted the Pulstar pulse plugs from Enerpulse ( earlier post ). Tags: ConceptEnginesEngines Fuel Efficiency.
