One of the major problems in internal combustion engines is emission of pollutans with exhaust gases. Those pollutants are not only harmeful for enviroment but also for humans. To decrease emmision of polu-tants many mechanical and chemical methodes are used in internal combustion engines especially in exhaust system such as TWC, DPF, SCR. Alternative way for decrease in exhaust gas pollutants is use of alternative fuel as a primary energy carier or as an additional fuel for base hydrocarbon one. In this studies the hydrogen was used as a additional fuel to methane. Both fuels were delivered to intake mani-fold. The share of the fuel was 100/0 methane/hydrogen and 70/30 methane/hydrogen. The addition of hydrogen to base fuel shown decreas of exhaust pollutants from engine and inrease in engine operating parameters.
