The diploma thesis focuses on the influence of combustion of CNG fuel and the production of exhaust emissions at a passenger car engine. At the beginning of the thesis are presented the possibilities of using fuel in vehicles. Then there will be described the CNG fuel itself, its advantages and disadvantages and there will be comparison with petroleum-based fuels. Next will be described necessary modifications of the engines and modifications of the related systems to make combusting of CNG possible, also summarize the theoretical knowledge of the possible effects on the output ecological parameters of the engines. These theoretical knowledges were verified by measuring the actual emission parameters of the engine of a real vehicles Skoda Octavia III Diesel and G-TEC. At the end of this thesis are measured values evaluated. Evaluation confirmed, that vehicles, which uses as fuel CNG, reaches lower emission than vehicles that are using convention oil-based fuels.
