Since 1 January 2012, Brazil has carried out significant changes in the technology of light and heavy diesel vehicles produced or imported into the country, as well as with regards to the fuel to be used as per the new Proncove - P7 phase of the control of air pollution motor vehicles
The new technology aims at reducing the limits of greenhouse gas emissions. Since January this year, Brazil has a new type of diesel oil called S50, due to the 50 ppm (parts per million) of Sulphur, which makes it less polluting. Even if S50 diesel was already introduced gradually in the country in 2009, its distribution became mandatory in all regions of Brazil in a radius of not more than 100 Km as of 1 January 2012. Another innovative situation is the use of a reducing vehicular agent called Arla 32, indicated for new heavy vehicles. This product has a base of industrial urea, specific for vehicle applications, and cannot be mixed with diesel fuel. For this reason, new truck will have a special tank to transport Arla 32, which can be identified by its blue cap. Basically speaking, the substance is injected in controlled dosages in the output of the exhaust gases of the vehicle, before the catalytic converter, with the aim of neutralizing Nox emissions. Arla 32 will be available in large Brazilian fuel distribution networks, as well as with heavy vehicles at dealers. The control programme for air pollution caused by motor vehicles (Proncove) is an initiative of the Consiglio nazionale per l'ambiente (CONAMA) - National Council on the Environment - and is coordinated by the Brazilian Institute for the Environment (IBAMA).
