Control Program of Air Pollution by Automotive Vehicle (PROCONVE) was created on 05/06/1986 by CONAMA through Resolution No. 18 as a means of quality control of air in the urban centers. It is an adaptation of the international methodologies to the Brazilian needs, such as Euro V, which is effective in Europe.
In Brazil, the decrease of the emission levels allowed has been progressively deployed since the first version of PROCONVE. It ensures that every release of new vehicles and national and imported motors work within the limits of emissions allowed. We are in the seventh phase (P-7) that foresees a significant decrease in the emission levels allowed for the heavy vehicles line produced from January 1st, 2012. In order to be met, the phase requires, besides the modifications in the motors, new Exhaust Gas Recirculation system and diesel with reduced sulfur content (for example, BR's S110 diesel).
Every exhaust pipe emission is strictly tested, quantified and compared to the limits set out by company registered at INEA (CREV – Registry Certificate – Vehicle Emission).
CECA Resolution No. 4.814 of 04/17/2007 which approved the guidelines set out in DZ-572.R4
