Design of opposed-cylinder free-piston linear generator from earlier works with single, centered linear generator. Most of this work focused on a similar design: a single linear generator placed between two opposed cylinders, as in the diagram at right from Shanghai Jiaotong. 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. The variable flow lube pump helps maintain engine efficiency.
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) Resources. Umierski, Th. Körfer, P.
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.
The objective of the consortium, which includes luxury car maker Jaguar Land Rover and leading electrical machine company SR Drives ( earlier post ), is to produce the first commercially viable gas turbine generator designed specifically for automotive applications. Jaguar Land Rover is now part of Tata Motors. One moving part.
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.
Swissauto Wenko AG of Switzerland produces a modern version of the Comprex—the Hyprex—designed for small gasoline engines. Combustion starts in the central part of the channel, where the fuel/air mixture is rich and flame propagates to inner and outer end of the cell. Earlier wave rotor implementation were mainly axial flow.
This project will look to improve the overall system design, with a synergistic focus on gears, bearings, surface treatments, lubricant flow and lubricant composition. This project is part of a £40-million (US$63 million) ETI program designed to increase HDV efficiency.
The companies are developing an improved axial vane type rotary engine known as the RadMax. The RadMax design was mainly developed by Radian Milparts and assigned to REGI US, Inc. The new vane actuator assembly reduces weight and friction, and the vane actuator design does not require any return springs. in December 2005.
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% 25 city car as the test bed, Shell engineers formulated an ultra low viscosity 0W-10 motor oil. benefit on a combined cycle.
By combining HEHC with a rotary engine architecture, LiquidPiston has created an engine that is up to ten times lighter, quiet, and two to three times more efficient at part-load than conventional engines. We have explored and patented dozens of engine architectures capable of implementing the HEHC cycle.
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%
Shifting the operating point of the engine is also possible, using at least one cylinder in a conventional combustion manner at high load, and using at least one cylinder to pump air into the pressure tank. In large naturally-aspirated SI engine, high-friction, pumping losses and part-load operation all contribute to poor fuel efficiency.
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.
Methanol and ammonia are the fuels of the future and we are excited to continue to play a part in the transition to zero carbon through this partnership. MAN’s methanol-fueled ME-LGIM engine inherits well-known aspects and features of the standard MAN B&W two-stroke diesel engine. Source: MAN. Source: MAN.
Bosch’s 15-inch monitor has two variants, one in landscape mode as a dashboard solution and another in portrait mode as part of a mirror camera system that can replace side mirrors and improve vehicle efficiency by reducing drag. Powertrain concepts. The Bosch Central Gateway (CGW) enables secure connectivity in commercial vehicles.
The LowCVP Technology Challenge is supported by the Institution of Mechanical Engineers (IMechE) and with an associated media partner, Cleantech Investor. The Libralato engine is a rotary engine comprising two interlaced circular chambers of slightly different diameters. Overview of the Libralato Engine. Click to enlarge.
Combining the high compression ratio with the Atkinson cycle, the engineering team demonstrated a 7.4% As part of the study, the team also demonstrated switching durability of the dual piston mechanism of more than one million cycles.
