In this article method of a visualization of a process of injection and burning of the air-fuel mixture was presented in cylinder of engine GDI. Intention of the visualization is a possibility of a determining and a selection how the most profitable parameters of injection for the work of engine during burning of the various load. Apparatus of the firm AVL - VideoScope 513 D was used to performance of positional tests, having on purpose registration of a dislocation of the stream of the fuel from the moment of injection, one by one a reflection of fuel from of the bottom of the piston until for the connection under the spark plug, and next an expansion of the flame from moment of the ignition until to the end of process of burning. Results of carried out visualization are in form files of the type of avi. These files are intended to a presentation of a record of respective frames as a moving image. From editorial reasons in this article, results of visualization are presented in a form of single cinematographic frames following in turn after themselves what the certain degree of the angle of the rotation of the crankshaft. Values of angles for which next frames were presented are placed in a bottom left corner of a single frame. All executed registrations archive images in the function of angle of rotation of crankshaft no from one, but from many of the cycles of the work of engine
