Modern energy systems combine a large number of different generators, storage systems and consumers. In addition, flexibility and resilience requirements are increasing. LEC ENERsim is a simulation platform for optimizing such systems, from the early design phase to commercial operation. LEC ENERsim allows the assessment of technical performance, self-sufficiency, as well as economic and ecological evaluations.

Investigation of injectors for large bore gas engines used for alternative fuels in an optically accessible injection chamber
In order to achieve future climate targets, the decarbonisation of fuels and, subsequently, the development of suitable injection systems and large engines are in the focus of development activities. Fuel preparation and in particular the injector play a central role in robust and low-emission engine operation. In order to better understand the injector behaviour and validate the simulation models, the…
Experimental evaluation of lubricant suitability and performance in ammonia-powered engines
As the demand for low-emission and carbon-neutral fuels increases, ammonia has emerged as a promising alternative fuel due to its carbon-free molecular structure and established production and distribution infrastructure. However, the use of ammonia as a fuel introduces new challenges, particularly in engine lubrication. Ammonia combustion can lead to the formation of reactive emissions such as NOx and unburned ammonia,…
LEC Data Challenge 2025
https://www.lec.at/news-entries/lec-data-challenge-2025/?lang=en
With the LEC Data Challenge 2025, we would like to encourage students and practitioners of various disciplines who are enthusiastic about data to develop a data-driven solution that accurately predicts key engine performance parameters for a wide range of engine control parameter settings. The challenge is not only to use engine control parameters as model inputs, but also to incorporate…
