Status of Emission Control Science and Technology in Argentina

With a current population of 44 million inhabitants  the Argentine Republic has an automotive fleet of over 14 million vehicles,  i.e., a rate of 3.5 inhabitants per vehicle (not taking into account freight transport lorries, passenger transport vehicles, or motorcycles). In the last decade, the number of vehicles in use has practically doubled, having gone from 7.4 million vehicles in 2007 to 14.4 million in 2017 (not taking into account approximately 7 million of motorcycles)
Based on the information available between 1980 and 2017, it is clear that the composition of the entire Argentine automotive fleet by fuel type is 33% of diesel vehicles, 55% of gasoline vehicles, and 12% of vehicles have been converted to CNG.

- Between 1995 and 2004, US EPA emission limits (according to US CFR 40 Part 86 to US Tier 0 standard) until 2004 for light vehicles and European Directives (88/77/EEC and post to EURO I and II standards) for heavy vehicles (Dec PEN 779/95).
- As of 2004, the EEC regulations for light and heavy duty are established including the following limits for the new designs:
❖ As of 01/01/2004 EURO II (Resolution SAyDS* 1270/2002) for light-duty vehicles 94/12/EC and heavy-duty vehicles 88/77/EEC.
❖ As of 01/01/2006 EURO III (Resolution SAyDS* 731/2005) for heavy-duty vehicles 99/96/EC.
❖ As of 01/01/2007 EURO III (Resolution SAyDS* 731/2005) for light-duty vehicles 98/69/EC.
❖ As of 01/06/2009 EURO IV (Resolution SAyDS* 731/2005) for light-duty vehicles 98/69/EC and heavy-duty vehicles 2005/55/EC.
❖ As of 01/01/2015 EURO Va (Resolution SAyDS* 1464/2014) Only light-duty vehicles M1** with GWV < 2500 kg 692/2008/CE.
❖ As of 01/01/2016 EURO Va (Resolution SAyDS* 1464/2014) for light-duty vehicles M1** with GWV > 2500 kg and N1** (692/2008/EC) and heavy-duty vehicles (2005/55/EC).

In the last decade, the entry of EURO V standards (Table 2) has suffered several postponements as a result of delays in the programs aiming to improve the environmental quality of traditional commercial fuels (gasoline and diesel). At the present, the higher prices of the better quality fuels (with lower sulfur content according to emission control technologies EUROIV and EUROV) as well as biofuel incorporation programs (current composition of 12% bioethanol in gasoline and 10% biodiesel in diesel), promoted as of 2006 by National Law 26093 on the Promotion of Biofuels, have generated a particular local scenario. This new scenario includes the impact of recent technological fraud committed by particular international manufacturer of diesel internal combustion engines as well as the challenges imposed by the issues of energy efficiency improvement and mitigation of global climate change through reduction of CO2 emissions.
In reference to the real technological composition of the vehicle fleet in use in Argentina, as almost 80% of the fleet is less than 20 years old  most have been subject to emission regulations and standards implemented in Argentina since 1995 (Table 1). In the case of the light vehicles fleet, most gasoline engines (including those converted to CNG or bi-fuel) have incorporated three-way catalysts or TWC (since 1999 all gasoline vehicles marketed in Argentina have TWC) and the diesel engines have been equipped with the Diesel oxidation catalysts (DOC) and in some cases exhaust gas recirculation (EGR) systems. The heavy diesel vehicular fleet (Fig. 3) that constitutes the passenger and freight transport is only 5% of the fleet in use, but consumes more than 50% of the vehicular fuel, in tons of oil equivalent . This fleet is composed of almost 60% of EURO III diesel technologies , because of the aforementioned delay in the entry of EURO V technologies (Table 2), while the remaining 40% (models over 10 years old) are older units with technologies Pre EURO, EURO I, and II.
Selective catalytic systems (SCR) with urea injection
EGR (in a few models mainly light-duty diesel)
On the other hand, the incorporation of particulate filters and oxidation catalyst is currently focused on the light-duty diesel (utilities and commercial vehicles) vehicles (GWV < 3500 kg), and is projected for heavy-duty vehicles with having EUROVI technologies.
Thus far, there is still no clear and formal implementation date for EURO VI emission Regulations in Argentina. However, taking into account the availability of fuels compatible with EURO VI technologies (Resolution SRH—No. 5/2016 Ministry of Energy and Mining), it could be expected that by 2019, it would be implemented for M1 light vehicles and by 2020 for vehicles N1 and N1/M1 and heavy vehicles (even taking into account the way in which EUROV was implemented).
