In order to eliminate the local CO2 emissions from vehicles and combat associated climate change, classic internal combustion engine can be replaced by an electric motor. The two most advantageous variants for necessary electrical energy storage in vehicle are currently purely electrochemical batteries chemical hydrogen with subsequent conversion into means of a fuel cell stack. also combined battery range extender, so that refuelled either electrically or using hydrogen. air compressor, key...
Additive manufacturing processes such as selective laser melting and electron beam require small particle sizes. A widely used technique to produce suitable powders is close-coupled atomisation. To further decrease the achieved sizes, annular geometry of gas nozzle changed a convergent–divergent (CD) profile. This novel configuration capable operating stably at low pressures 0.8 MPa above. Beyond that, unwanted effects lick-back are avoided. Different nozzles with conventional have been...
Surface doping of oxide nanoparticles is important in fields ranging from heterogeneous catalysis to optoelectronics. Here, we report the solvent-free synthesis mixed calcium-magnesium nanocrystals size range between 5 and 40 nm. Although CaMgO mixtures are thermodynamically forbidden on a macroscopic scale, Calcium ions can be distributed homogeneously MgO using chemical vapor deposition (CVD) as nonequilibrium technique. Subsequent thermal activation leads calcium ion segregation into...
Fuels from lignocellulosic biomass have the potential to contribute sustainable future mobility targets by reducing fossil CO2 emissions of transport sector. Of special interest for diesel engine are oxygenated fuels, since they can help solve traditional conflicts objectives like soot–NOx trade-off or efficiency–NOx compromise. Dibutyl ether (DBE) and oxymethylene ethers (OME) among most promising fuel candidates. The suitability these compounds engines is investigated in this study. fuels...
Reducing CO2 emissions is an increasingly important goal in general aviation. The dual-fuel hydrogen–kerosene combustion process has proven to be a suitable technology for use small aircraft. This robust and reliable significantly reduces due the carbon-free of hydrogen during operation, while pure kerosene or sustainable aviation fuel (SAF) can used safety-critical situations event supply issues. Previous studies have demonstrated potential this terms emissions, performance, efficiency,...
Reducing CO2 emissions in general aviation is a critical challenge, where battery electric and fuel cell technologies face limitations energy density, cost, robustness. As result, hydrogen (H2) dual-fuel combustion promising alternative, but its practical implementation constrained by abnormal phenomena such as knocking pre-ignition, which limit the achievable H2 share. In response to these challenges, this paper focuses on strategies mitigate irregular while effectively increasing...
<div class="section abstract"><div class="htmlview paragraph">Reducing CO<sub>2</sub> emissions is an increasingly important issue. In aviation, approaches such as e-propulsion only represent a solution for special applications due to the low energy density of batteries. Because low-cost and robust design combustion engines, this concept still most suitable general aviation. For defossilization, besides e-fuels bio-fuels, which so-called sustainable aviation fuels...
As part of a project to develop small batch metal atomisation system, based on free fall and close-coupled atomisation, the influence process parameters various powder quality features has been investigated, using copper–tin alloys as feedstock material. Particle size distribution, appearance satellite particles, particle circularity flowability were recorded criteria quality. From data obtained in these experiments, effects main (atomisation pressure, mass melt flow, height spray chamber...
The usage of ethanol and two different mixtures gasoline (E85 E65) was investigated on a modified diesel engine designed to work in dual-fuel combustion mode with intake manifold alcohol injection. tests were conducted at five operating points covering low, medium high load speeds. Additionally, an engine-process simulation model built for the test selected from bed measurements analysed it. discussion results allows efficiency analysis therefore better understanding findings stand...
