LEC DATA CHALLENGE 2021

Large Engines – Big Data: Can you handle the pressure at the second LEC Data Challenge?Background

The LEC focuses on developing environmentally sound, efficient and robust large engines for sustainable energy and transportation systems. Key to this development is the detailed knowledge of the processes inside the engine combustion chambers. In research and development, the combustion process is assessed by measuring and evaluating the corresponding in-cylinder pressure traces. Even in production engines, in-cylinder pressure transducers can be applied to facilitate advanced combustion control systems. In this way, each individual cylinder is operated in the most efficient way possible while combustion anomalies such as knocking or misfiring are avoided. Since high-quality cylinder pressure transducers come with a limited lifetime and at a relatively high cost, the LEC aims to employ alternative sensing methods which are more durable and less expensive. While such sensing methods may deliver substantially different information than pressure transducers, it is possible to use machine learning to determine the corresponding pressure traces.

LEC Data Challenge

With the LEC Data Challenge, we would like to encourage data-enthusiastic students and practitioners from various disciplines to develop a model that determines the in-cylinder pressure trace based on a corresponding signal from an acceleration sensor incorporated in the engine’s cylinder head. To this end, a training data set is provided consisting of the targeted pressure data as well as the acceleration sensor data. A second data set contains signals of the acceleration sensors only and the goal is to accurately determine the corresponding pressure traces.

Through the LEC Data Challenge you are free to use software and programming languages of your choice. For this reason, the data sets for training and testing are provided in the versatile CSV format. After completing the LEC Data Challenge the quality of your solution on the test set will be assessed using a measure for the average deviation from the true pressure traces. You will receive a detailed description of this error/loss measure once the LEC Data Challenge has started. Participation in the Challenge is possible from May 3 (earliest data release) to August 16, 2021. Data and detailed task description will be provided for download after successful registration. If you have any questions please contact us via data.challenge@lec.tugraz.at

RECAP-HYMETHSHIP FINAL STAKEHOLDER EVENT

Around 100 participants took the opportunity to get to know the results of the HyMethShip project. The event was announced by the project partners to their business contacts and was conducted online.
Registrations came from 18 countries and 4 continents, which shows how far the project has spread.

The business sector from which the audience came was also broad: The majority were researchers, with shipping companies, builders and operators accounting for the next largest share. Engine manufacturers and other industries were also well represented, as were consultants and engineering firms, classification societies and administrations.

Four expert presentations gave authentic and detailed information about all involved technologies, how these are working in combination to ensure an efficient propulsion system and driving the carbon capture and storage components with the waste heat of the engine (Dr. Nicole Wermuth, LEC). The HyMethShip concept was evaluated to be particularly suitable for Passenger and cruise ships on travels up to 600 nautical miles and for bigger ships (tankers and Ro-Ro cargo ships on high sea voyages (Dr. Joannes Ellis, SSPA). Promising are also the results of the environmental and the cost assessments by means of a LCA- and a LCC-study (Dr. Selma Brynolf, CTH) as well as the safety assessment (Dr. Alex Pedgrift, Dr. Abhijit Aul, Lloyds Register).

The tenor of the discussion was that the HyMethShip system could prove its feasibility and represents an attractive way to achieve far-reaching decarbonization of the shipping sector. The elegance of the system is especially reflected in the closing of the carbon cycle which is achieved by incorporating a pre-combustion carbon capture process.

The interest of the participants was high, and was also demonstrated by the fact that all stayed until the end of the event.
