Study on the Construction of an Urban Liquefied Natural Gas Bus and Its Cold Energy Recovery

Abstract As the green energy of urban bus, liquefied natural gas (LNG) is used more and more widely, which has played an important role in solving the urban pollution. An urban bus is chosen as the research object, the construction of its LNG fuel modification and the project design of its cold energy recovery are studied in the paper. The power and economy tests are carried out after the modification for the urban bus, and the referential results are obtained for the modification of in-used urban bus.
