The growth in the use of methane fuel for fuelling urban buses

Urban transport vehicles have a large share in city traffic. This results in higher emission of hazardous substances and poses direct threat for human life by causing smog. Research and implementation works are underway to prevent this situation. In city transport attention is given to electric and hybrid vehicles, as well as gas vehicles that are used. The last group, i.e. city buses with engines fuelled with methane fuels have positive impact on decreasing emission of certain hazardous substances. This article addresses internal tests and their results that confirm the rationality underlying the use of these fuels in city transport buses
