Exhaust emissions of buses LNG and Diesel in RDE tests

The article compares the exhaust emissions in road conditions of city buses: LNG and Diesel. Both buses met the Euro VI exhaust emission norm. The current strong drive to diversify fuels in Poland and the creation of a large gas port in Świnoujście for LNG imports creates an excellent opportunity to...
