The paper discuses results of research concerning fuel injection and combustion processes using high pressure gasoline injection realized by two injectors positioned in Constant Volume Chamber and Rapid Compression Machine. To get images of injection and combustion processes high speed camera HighSpeedStar 5 was used. The images were analyzed by LaVision DaVis software. The injection was realized using outward-opening piezoelectric injectors getting empty inside conical stream. Injectors are positioned with right angle between them with spark plug amid them. The angle of cone equals 90 degrees, which enables to get connection of fuel streams around spark plug electrodes allowing ignition of mixture. The research on combustion processes was made using different injection strategies. Analysis of computer simulations broads the range of obtained information. The led research enables to verify the validity of usage of two injectors in combustion chamber in Gasoline Direct Injection.
