LEC infrastructure

Test bed infrastructure for large engine development

Our vision & mission

Our vision is to create the basis for the next generation of environmentally sound, efficient and robust large engines and to become the world’s leading research institution in the area of combustion technologies for large engines.

We aspire to achieve this vision by pursuing the following goals:

  • To optimally describe the overall system and all combustion-related components by bringing together the competences of national
    and international technological leaders in this area
  • To expand from a purely thermodynamics-oriented methodology to a multidisciplinary approach to research which describes the overall system
  • To continue to expand the superior large engine research infrastructure and to enhance the simulation-based development methodology
  • To conduct extensive basic experiments that support the development of simulation models by taking relevant physical effects into account
  • To improve analysis concepts for reliable evaluation of experimental results
  • To recognize future trends in the area of engine technology, fuels and lubricants for large engines
  • To function as a trendsetter in the enhancement of methodology with a view to optimizing the overall system
  • To derive innovations and development tools that can be implemented by the company partners
  • To define challenging topics for scientific research
  • To create jobs for highly qualified researchers with long-term prospects by providing suitable structures
  • To set up an excellent and internationally oriented research center in Austria

Organizational structure

The CEO of LEC GmbH is responsible for the scientific and financial management of the COMET-K1 center. The Supervisory Board (which also constitutes the Strategy Board), the Program Committee and the International Scientific Advisory Board advise and support the management. Internally, the CEO is supported in managing the center by specific administrative units.
Areas A, C, D and S are concerned with implementing technology-related topics in the research program. Area X spans the other areas and supports their research.

LEC infrastructure

The LEC has an extensive test bed infrastructure for large engine development with single cylinder research engines at its disposal.

  • Four test beds with single cylinder research engines
  • Highly flexible research engine design (more than sixteen possible configurations)
  • Charge air compressor for producing the effect of two-stage turbocharging (up to 10 bar)
  • Operation possible with different liquid and gaseous fuels
  • Efficient safety plan (for operation with H2, CO, etc.)
  • Sophisticated measuring equipment
  • High pressure gas supply (up to 600 bar)
