CIMAC was founded in May 1950, the first Congress took place in 1951. Originally CIMAC was organized as an industry event to discuss new ideas and developments within the engine and components industry together with institutes and universities. This massive amount of professional up-to-date knowledge is still available among the CIMAC members and is presented during the Congresses. A very decisive change, however, has taken place over the years - the clients of the engine industry have become interested in participating in the CIMAC Congresses!

Now being more than 60 years old, CIMAC places an even greater importance on the user attendance by attracting more papers from operators and designers of ships, power plants and locomotives.

On the occasion of the 27th CIMAC World Congress in Shanghai in May 2013, a 2-stroke Diesel Engine History Booklet has been published, written by Jørn Dragsted. The booklet is available for download here.
