STUDIES ON THE FUEL-SPRAY COMBUSTION CHARACTERISTICS IN A DIESEL ENGINE BY THE AID OF PHOTOGRAPHIC VISUALISATION

The paper presents a report on the influences of air swirl on the combustion performances of direct injection diesel engines at the 16th CIMAC Congress held in Oslo, demonstrating various factors affecting the optimum swirl intensity. In the present studies the authors have rebuilt the test engine used in the above experiment to take high-speed photos from the lower part of the combustion chamber and examine the correlations between fuel-spray dispersion and combustion characteristics with the aid of photographic visualisation. Results show that combustion performances can be estimated with the relative swirl intensity. The effects of the combustion chamber's shape and injection pressure on the formation and oxidisation of the soot have been clarified. Also the combustion characteristics of fuel spray in the side-injection system have been investigated.
