For R. Fernandes, chairman of the Latin American NGV Association (ALGNV), in this scenario the main alternative to diesel has been natural gas. “In Latin America as a whole, the panorama of CNG is positive. Natural gas in heavy transport has already been used for over twenty years, especially because of its benefits, such as reduction in 40% of the pollutant emissions caused by diesel. The noise from the diesel engines can also be reduced in 50%, as it has been demonstrated in others countries and in laboratory tests conducted in Brazil,” said the executive. In addition, he indicated that another main benefit about substitution is the increase in national energy security.
The expansion of CNG use not only for light vehicles but also for heavy vehicles is one of the premises of the project shaped by the Secretary of State for Economic Development, Energy, Industry and Services of Rio de Janeiro (SEDEIS-RJ) and the Department of Transport of Rio de Janeiro (SETRANS-RJ).
According to Jorge Loureiro, superintendent of gas from SEDEIS-RJ, the program to boost CNG in the bus fleet of the metropolitan region of Rio de Janeiro is estimated to be operating for the 2014 World Cup.
Among the topics that were discussed on the last day of the event, it is worth mentioning the experiences in Latin America about the use of CNG in heavy vehicles; the introduction of the diesel/gas conversion kit (industry development and performance); the vision of the engine manufacturer on the new technology; and the analysis of CNG regulation in heavy vehicles in Brazil.
