Results of the preliminary numerical study of the methane direct injection system for spark ignition engines are reported. Poor penetration and mixing of the gaseous fuel jet with the air in the engine cylinder create serious difficulties in choosing right injection parameters especially for the nearTDC injection when very short time for mixing is available. The twodimensional numerical simulations of the methane direct injection system were performed with the use of the KIVA3V computer code. The presented results of numerical analysis enable an estimation of the influence of injection timing and direction on the mixing process and combustible mixture zone width and position. These results create the base for the further numerical investigation of the engine combustion system with methane direct injection, which will be performed together with experimental research.
