Previous issue date: 2006-06-23 / The use of Natural Gas Vehicle has had a fast increase lately. However, in order to have a continuous success this Program needs to develop converting devices of Otto-cycle engines, gasoline or alcohol, to the use of NGV (Natural Gas Vehicle) that presents low cost, maintaining the same original development of the vehicle and low level of emissions, considering the PROCONVE rules. Due to the need to diversify the matrix in order to avoid energetic dependence and due to strict pollution control, it has increased in the Brazilian market the number of vehicles converted to the use of NGV.
The recent regulation of the PROCONVE, determining that the converted engines with kits should be submitted to emission testing, comes to reinforce the necessity of the proposed development. Therefore, if we can obtain kits with the characteristics already described, we can reach a major trust in the market and obtain an increase acceptance of the vehicle conversion for NGV. The use of natural gas as vehicle fuel presents several advantages in relation to liquid fuels. It is a vehicle fuel with fewer indexes of emissions when compared to diesel; their combustion gases are less harmful, with a major level of safety than liquid fuels and the market price is quite competitive. The preoccupation that emerges, and the motivation of this project, is to know which are the main justifications for such technology, well accepted in other countries, with a low index or emission, with a high level of safety, where its maintenance becomes low, reminding that for this it is necessary that this technology has to be used properly, and once available in the market will not motivate interest in the urban transportation companies in Brazil, in research centers in general. Therefore this project exists to show the society in a general way the current vision of the main governmental factors, of the national research centers and of the private companies concerning the use of natural gas vehicles in urban transport vehicles, in order to give a major reliability to the population as well as to motivate national market competitiveness with a low cost and reliable product and to enrich the national technology / O uso do g?s natural veicular tem tido um crescimento acelerado nos ?ltimos anos. No entanto, para que esse Programa tenha um sucesso cont?nuo, faz-se necess?rio desenvolver dispositivos de convers?o de motores do Ciclo Otto, a gasolina ou ?lcool, para o uso de GNV (G?s Natural Veicular) que apresentem baixo custo, conservando o mesmo desempenho original do ve?culo e baixo n?vel de emiss?es, atendendo as normas do PROCONVE. Devido ? necessidade de diversifica??o da matriz a fim de evitar depend?ncia energ?tica e devido aos r?gidos controles de polui??o, cresce no mercado brasileiro o n?mero de ve?culos convertidos para a utiliza??o de GNV. A recente regulamenta??o do PROCONVE, determinando que os motores convertidos com "Kits" sejam submetidos a ensaios de emiss?es, vem refor?ar a necessidade do desenvolvimento proposto. Desta forma, se conseguimos obter "Kits" com as caracter?sticas j? descritas, poderemos alcan?ar maior confian?a do mercado e obter uma crescente aceita??o da convers?o de ve?culos para GNV.
O uso do g?s natural como combust?vel apresenta diversas vantagens em rela??o aos combust?veis l?quidos. ? um combust?vel com menor ?ndice de emiss?es quando comparados com o diesel, seus gases de combust?o s?o pouco nocivos, com um grau de seguran?a maior que os combust?veis l?quidos e o pre?o no mercado ? bastante competitivo. A preocupa??o que surge, e a motiva??o deste projeto, ? saber qual as principais justificativas para que uma tecnologia, bastante aceita em outros pa?ses, com um baixo ?ndice de emiss?o, com alto n?vel de seguran?a, onde sua manuten??o se torna baixa se utilizada de forma adequada e dispon?vel no mercado, n?o faz aflorar interesses nas empresas de transportes urbanos no Brasil, nos centros de pesquisas em geral. Assim este projeto vem para mostrar ? sociedade de uma forma geral a atual vis?o dos principais atores governamentais, dos centros de pesquisas nacionais e das empresas privadas a respeito da utiliza??o do g?s natural em ve?culos de transporte urbano, a fim de passar uma maior confiabilidade ? popula??o, al?m de incentivar a competitividade do mercado nacional com um produto de custo acess?vel e confi?vel e enriquecer a tecnologia nacional
