The paper reports the schlieren technique apply in investigating combustion processes in a DI diesel engine. The design of the schlieren system and the high speed photo-graph control system are described. The paper analyses effects of the air swirl intensity on the injection fuel and the flame propagation in the cylinder with the aid of photo-graphs. The conclusion is that the schlieren technique is an important method for investigating the combustion processes in I.C engines.
