Argentina: On-Road Vehicles and Engines

Passenger Cars

Emission standards for new passenger cars in Argentina are summarized in Table 1. Since 2004, the standards are based on European light-duty vehicle emission regulations.

Table 1
Emission Standards for Diesel Cars

Year	Reference Standard	CO	HC	NOx	PM
		g/km
1994		24.0	2.1	2.0	-
1996		12.0	1.2	1.4	0.373
1998		6.2	0.5	1.43	0.16*
2000		2.0	0.3	0.6	0.124
2004	Euro 2
20071	Euro 3
20092	Euro 4
* 0.31 g/km for vehicles above 1700 kg 1 - New models; 2009 for all models 2 - New models; 2011 for all models

The limits for 2007 and later light-duty vehicles established by Resolution 731/2005 are those of European Directive 1998/69/CE Stage A and B as opposed to limits that are numerically equal. European Directive 1998/77/CE is the required methodology. Compliance with the low temperature Type VI test is not required. The application of modifications in the methodology for evaporative emissions (Type IV test) established in European Directive 1998/69/CE and the requirement for OBD systems are only necessary starting January 1, 2008.

Historically, passenger cars in Argentina could also be emission certified (homologated) using an alternative option of certifying the car engine to the light commercial vehicles (LCV) emission standards, Table 2.

Trucks and Buses

Emission standards for new diesel fueled trucks and buses in Argentina are summarized in Table 2 [Decree 779/95; Resolution 731/2005]. Through the 2000 stage, the standards were also applicable to light commercial vehicles (LCV, engine certification), as indicated. The standards are based on European heavy-duty engine emission regulations.

The limits for 2006 and later heavy-duty engines established by Resolution 731/2005 are those of European Directive 1999/96/CE Stage A and B1 as opposed to limits that are numerically equal.
