When reforming is not used, the fuel and exhaust pass through CV2 unchanged. 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). The syngas is then burned in the engine in place of some or all of the original fuel.
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.
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. In December 2020, Achates Power announced that their 10.6L
The basic idea of the new Diesel combustion illustrated in this paper is to control the heat release rate by a gradual supply of an almost homogeneous charge, without relying on exhaust gas recirculation to moderate the reaction. Thus the HCPC range can extend to all engine operating conditions, including very high loads.
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.
The award will allow a team of MSU engineers and scientists, led by Norbert Müller, an associate professor of mechanical engineering, to begin working toward producing a vehicle-size wave disc engine/generator during the next two years, building on existing modeling, analysis and lab experimentation they have already completed.
A cryogenic engine such as the Dearman piston engine produces zero emissions at the point of use; has low greenhouse gas emissions provided the liquid air or nitrogen is produced from low carbon electricity; has energy and power density on a level with battery electric technology; and has the potential for rapid refueling.
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. g/kWh engine-out NO x. Click to enlarge. The OP4 is a two-stroke, inline two-cylinder, four-piston diesel with a swept volume of 1.5
An adaption of cylinder de-activation technique called ECONAMIQ over-expansion can be applied to engines to improve fuel efficiency. Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation.
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. This new funding opportunity announcement will be available in early February.
It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve. The utilization of compressed air power on engine cool starts and low-load conditions could significantly reduce the overall emissions. … Then it charges the compressed air storage tank.
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.
