History
The motor vehicle emission control program in Brazil is known as Programa de Controle da Poluição do Ar por Veículos Automotores (PROCONVE). Heavy-duty vehicle emission standards ("P" standards) generally follow the European precedent for numerical emission limits and certification test cycle. Important regulatory steps in Brazil are summarized in the following table:

MY 1994-2002
Emissions standards for new MY 1994-2002 diesel fueled trucks and buses in Brazil are summarized below. The same standards also applied to light-duty trucks. All truck and bus engines, including those used in light trucks, are certified on an engine dynamometer (test cycle ECE R-49).

In addition to the above standards, new engines must meet the following free acceleration smoke limits (effective March 1994):
 * 0.83/m (30 HSU) for naturally aspirated engines
 * 1.19/m (40 HSU) for turbocharged engines

MY 2006 and Later
More stringent standards applicable to heavy-duty engines effective 2006 are summarized below. Diesel engines are tested over both the ESC and ETC tests, while gas engines are tested over the ETC test only (see also EU regulations). The P7 stage also introduces a 25 ppm limit for ammonia (NH3) to be met over both test cycles.
