Abstract
For the HCNG bus using fuel which is the mixture gas of hydrogen and natural gas, the fuel efficiency and $CO_2$ emission characteristics were analyzed based on the WHVC test results and compared with that of the CNG and diesel buses. $CO_2$ emission characteristics were also analyzed by contribution effects such as carbon emission factor and fuel consumption. As a result, the fuel economy of HCNG bus was evaluated to be 11.5% improvement compared to CNG bus, and it was also showed equivalent to diesel bus. In addition, the $CO_2$ emission of HCNG bus was reduced 20.4% and 34.5% compared to CNG bus and diesel bus respectively. It was concluded that the $CO_2$ emission characteristics were influenced by the carbon emission factor depending on fuel composition and the fuel consumption according to the engine performance.
