Who we are

We have 40 members from some 15 countries worldwide, including:

  • Gas engine manufacturers
  • Component suppliers to the gas engine industry
  • R & D organizations, consultants and universities
  • Oil and gas companies
  • Classification societies


What we do

We deal with aspects of internal combustion engine technology covering gaseous and other low flashpoint fuels by discussing and producing various information documents and statements of interest both to our industry and the public in general. We focus on systemic and operational aspects and give technical insights into details when necessary to understand the context. We collaborate with the other CIMAC WGs and embed their expertise in our documents and statements. The key aspects we are dealing with are:

  • Engine technology, systems and applications
  • Engine performance and operation
  • Engine raw emission characteristics
  • Safety and regulatory aspects

Our current projects and activities

      • Gas quality discussions related to the use of LNG, possible hydrogen-enrichment of natural gas and the need for improved knocking-stability definitions of fuel gases.
      • Input to the ongoing work within IMO with the “International Gas Fuel Code”.
      • About greenhouse gas emissions from gas engines.
      • Information document about the use of gas engines in the marine industry.

Latest publications

Various position papers on several gas engine topics, such as the following:


Meeting activities
