Ammonia and hydrogen are promising future fuels for reducing greenhouse gas emissions from large engines. Since the flame propagation of ammonia and hydrogen differs fundamentally from that of conventional fuels, this work aims to investigate the relevant combustion phenomena of ammonia and ammonia-hydrogen mixtures.Target: This master’s thesis aims to carry out high-speed schlieren measurements on the laminar and turbulent burning…

Experimental characterization of the flow conditions in a turbulent combustion chamber
The turbulent combustion behavior of future fuels such as ammonia and hydrogen differs fundamentally from that of conventional fuels and will therefore be investigated in fundamental studies in a new turbulent combustion chamber at LEC. For this, the flow conditions in the combustion chamber are to be characterized in advance.Target: Fans generate an almost homogeneous, isotropic turbulence field with a…
Roadmap towards robust hydrogen combustion
https://www.lec.at/news-entries/lec-publication-towards-robust-hydrogen-combustion/?lang=en
The paper “Towards Robust Hydrogen Combustion: Precise Lube Oil Consumption Measurement as an Enabler for Tackling Pre-Ignition” focuses on one of the central challenges in the development of hydrogen combustion engines: the reduction of pre-ignition through precise lube oil consumption measurement.
PhD position with research focus on exhaust gas aftertreatment for large ammonia engines (m/f/d)
Ammonia is currently the subject of increased interest as potential renewable energy carrier and alternative fuel for large internal combustion engines. However, the use of ammonia as a fuel brings new challenges not only regarding the combustion concept but also for the exhaust gas aftertreatment. In order to meet the increasingly demanding requirements for minimum pollutant and greenhouse gas emissions…

Development of a virtual pressure transducer for engine control
For environmentally sound, efficient and robust large engines, it is essential to have a detailed knowledge of the combustion process. In-cylinder pressure transducers are often applied in advanced combustion control systems. This allows each cylinder to be operated efficiently while avoiding anomalies such as knocking or misfiring. Since high-quality cylinder pressure transducers come with a limited lifetime and at a…
LEC illuminates for “Orange the World”
https://www.lec.at/news-entries/lec-illuminates-for-orange-the-world/?lang=en
The UN campaign “Orange the World” has been raising awareness of violence against women and girls since 1991: from the International Day to End Violence against Women on November 25 to December 10, Human Rights Day. This year, the UNiTE campaign is #NoExcuse during the 16 days of activism against gender-based violence under the slogan “Every [11] minutes a woman…
Data-driven condition monitoring of sliding bearings in large engines based on acoustic emissions
The combination of acoustic emissions and machine learning offers great potential for gaining deeper insights into the condition of large combustion engines. In particular, sliding bearings, which play a key role in ensuring the performance and safety of large engines, are a promising target for such monitoring. Target The aim of the present thesis is to develop a non-invasive method…

Are green fuels really green?
https://www.lec.at/news-entries/are-green-fuels-really-green/?lang=en
A research team at the LEC has developed an innovative method for certifying ‘green’ fuels. The aim is to support decarbonisation and increase confidence in green energy sources. By measuring isotope ratios, the LEC’s method makes it possible to accurately analyse fuels and their origins.
