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.
Schematic of the conceptual ideal piston engine used for the TCR study. 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.
The Scuderi Engine is a split-cycle design that divides the four strokes of a conventional combustion cycle over two paired cylinders. The Scuderi Engine is a split-cycle design that divides the four strokes of a conventional combustion cycle over two paired cylinders. a more efficient internal combustion engine. Earlier post.).
of the OX2 Engine. Advanced Engine Technologies. says it has reached the final development stage of its OX2 rotary engine, achieving a performance objective of more than 300 lb-ft (407 N·m) of torque along with 46 hp (34 kW) at an approximate operating speed of 760 rpm. Exploded view. Click to enlarge. OX2 in a test rig.
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. Using GMD’s new T.25
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 optically-bonded display enables future safety and automated solutions as it is easily integrated with advanced driver assistance technologies. 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.
liquid air) Dearman piston engine. Source: Dearman Engine Company. The work was conducted by a collaboration including industrial partners Arup, Dearman Engine Company, E4 Tech, Highview, Messer Group and Ricardo, as well as academics from the Universities of Leeds, Birmingham, Strathclyde, Brighton and Imperial College London.
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., The engine is classified as a turbine, says Jim Andrews, vv-tec’s President, because the use of the sinus discs make the engine into an impulse turbine.
The effects of [HCCI] operation will be investigated by future accurate combustion model. The control method of linear generator and the movement of free-piston will be investigated, and special attention will be [paid to] the synchronization of th left and the right pistons. —Huang et al.
An engine that provides vehicle manufacturers with an immediate solution for low emission legislation will make its European debut at the Engine EXPO in Stuttgart. The split-cycle engine from the Scuderi Group offers high efficiency standards without the need for large investments to modify existing production processes.
Rendering of the Grail Engine. Grail Engine Technologies , 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 ). Elements of the Grail Engine. Click to enlarge. Matthew Riley.
The partnership involves using select conventional vessels from EPS’ existing tanker fleet that use MAN engines to be retrofitted, allowing them to be powered by methanol and ammonia which will be supplied by OCI. Also, EPS will construct newbuild vessels with MAN engines powered by the same two alternative marine fuels.
UK-based Libertine FPE has built a demonstration prototype of its linear electrical machine for what it is calling “Digital Piston Motion Control” in free piston engine applications. This technology will allow researchers to develop future combustion engines free from the piston motion constraints dictated by the crankshaft.
