Improving computational algorithms requires reliable experimental data, including in the field of modeling gas-dynamic processes in piston engines. This work evaluates the possibility of using the schlieren method to study wave processes in the gas exchange system of an internal combustion engine. A schematic diagram is presented of an experimental setup based on the schlieren method using a single spherical mirror. A numerical calculation of the gas flow in the intake manifold is carried out and graphical dependences of the gas temperature and density on the angle of rotation of the crankshaft of the piston engine are presented. The requirements for the equipment necessary for the study are determined and a comparison is made between the analogs that meet the requirements.
