Argentina: Heavy-Duty Engines

Emission Standards: MY 1994-2005

Emission standards for new, model year 1994-2005 diesel fueled trucks and buses in Argentina are summarized in Table 1 [Decree 779/95]. The standards were based on European heavy-duty engine emission regulations. The standards were also applicable to engines used in light commercial vehicles (LCV), as indicated.

**Table 1**
Emission standards for diesel trucks and buses: MY 1994-2005
Year	Reference	CO	HC	NOx	PM	Applicability
Year	Reference	g/kWh				Applicability
1994	Euro 0	11.2	2.45	14.4	-	Urban buses
1995	Euro I*	4.9	1.23	9.0	-	Urban buses
1996	Euro I*	4.9	1.23	9.0	0.4^a	LCV & trucks
1998	Euro II	4.0	1.1	7.0	0.4^a	Urban buses
2000	Euro II	4.0	1.1	7.0	0.15^a	LCV & trucks
* production conformity limit ^a multiply by a factor of 1.7 for engines below 85 kW

Emission Standards: MY 2006 and Later

Since 2006, Argentina has been adopting EU heavy-duty emission standards by reference. The implementation schedule is summarized in Table 2. While Euro IV standards were adopted, this stage was effectively bypassed by the allowance of Euro III certifications until the implementation of Euro V standards. While there was some interest in adopting Euro VI standards, no formal legislative process has been announced [6338].
