The relations between methane/hydrogen proportions in fuel blend are presented in this paper. The research cycle carried out contains results of dynamometer chassis tests complemented with mathematical model calculations. An object of X16SZR engine installed in Opel Astra I was investigation. The engine has been equipped with additional CNG feeding system where fuel is being injected into intake manifold under low pressure. 8 fuel blends were tested with variable methane/hydrogen volume proportion (%): 100/0, 95/5, 90/10, 85/15, 80/20, 70/30, 60/40 and 50/50. The feeding and ignition systems were controlled by nominal drivers. In every measuring series engine was tested in the following steady states: on idle, high speed without load and full power at discrete variable speed in range 1500…3500 rpm. The main aspect of the analysis was to identify the influence of hydrogen share on engine parameters such power, fuel consumption, in-cylinder pressure, temperature and exhaust gas composition. Very significant ecological fact possibility of CO2 emission reduction has been identified. Result of increasing content of hydrogen in fuel mixture is engine knocking. Analysis carried out on the basis of results allowed it to the point on methane/hydrogen proportion in fuel blend considering a total efficiency, emission and heat flux in parts of combustion chamber in engine.
