One of the elements significant for the testing of combustion engines is the equipment for measurement of air consumed by the engine. The air excess coefficient, which depends on air consumption, is an important variable required for classification of combustion processes and evaluation for engine gas emissions. The paper deals with the solution of a flow field of a designed non-standardized measuring element with the objective of measurements and control of the air excess coefficient of the non-conventional combustion engine. In particular test stand (combustion engine – absorptive cooling equipmen)t, measuring element of the suction section of the combustion engine, modeling of the boundary layer, distribution of velocities and pressure field, distribution of density and temperatures in the flow field, course of static pressure and velocity in the measuring element axis for the engine torque, velocity profiles in cross sections, regulation of y+ parameter, comparison of velocities in dependence on torque, comparison of mass flow and pressure difference, contour of kinetic turbulent energy m2.s-2 for standardized and non-standardized measuring element, search dependence are presented in the paper.
