Fuel mixture formation inside a cylinder has become used more frequently in spark ignition engines in recent years. gas internal combustion engines can also benefit from this concept as direct injection into an engine 's cylinder during the compression stroke not only increases its volumetric efficiency but also eliminates adverse anomalies in the combustion process. This paper focuses on the development of a simulation model for a spark ignition engine with direct hydrogen injection into a cylinder. The Wave software was used for the simulation. A part of the paper depicts the model's verification. The study utilized a three-cylinder internal combustion engine with the total cylinder volume of 1.2 dm3. The concept of the engine is based on new, high-pressure injectors with 10 MPa inlet pressure (gas-hydrogen injection directly into the engine cylinder). Utilization of internal fuel mixture formation can be beneficial due to its enabling the control of the combustion process and gaseous emission generation. From the viewpoint of the engine's design, however, internal fuel mixture utilisation is more complicated as injectors have to be built into the cylinder head. The actual engine construction is housed in laboratories of the Technical University of Liberec, Department of Vehicles and Engines.
