Emission Standards » Chile

Light-Duty Vehicles

Background

First emission standards for new light-duty and medium-duty vehicles applied from model year 1992 in the Santiago Metropolitan Region (RM) and from 1994 nationally. These early standards were based on US emission requirements.

Since model year 2005/2006, there are two alternative emission compliance options:

  • US-based emission standards, with EPA Tier 2 Bin 5 based standards effective from 2013/2014, and
  • European-based emission standards, with Euro 5 based standards effective from 2013/2014.

No on-board diagnostic (OBD) requirements are indicated in Chile’s emission standards.

Light-duty vehicles include passenger cars and light light-duty trucks (GVWR < 2700 kg). Medium-duty vehicles are heavy light-duty trucks (2700 ≤ GVWR < 3860 kg).

Model Year 1992-2006

Early emission standards for passenger cars and light trucks, which were based on US 1984 regulations, are shown in Table 1 [2947][2948]. These standards first applied in the Santiago Metropolitan Region and in the continental parts of Region V and Region VI. The test cycle was the US FTP 75. The standards are updated from time to time.

Model Year 2005 and Later

More recent emission standards are summarized in Table 2.1 and Table 2.2 for diesel fueled vehicles and in Table 3.1 and Table 3.2 for gasoline, CNG and LPG fueled vehicles.

Standards for light- and medium-duty vehicles reflecting US Tier 1 and Euro 3 standards came into effect in 2005 for RM and 2006 nationally. For light-duty diesel fueled vehicles operating in RM, standards based on California Tier 1 and Euro 4 were adopted for 2006/2007 and were tightened to EPA Tier 2 Bin 5/Euro 5 levels in 2011. EPA Tier 2 Bin 8/Euro 4 based standards for light-duty vehicles with a spark ignition engine operating in RM applied in 2011. For medium-duty spark ignition and diesel fueled vehicles operating in RM, standards based on EPA Tier 1 Bin 8 and Euro 4 levels came into effect in 2011. For medium-duty diesel fueled vehicles, these were be tightened to EPA Tier 2 Bin 5/Euro 5 in 2012.

The US based standards adopted prior to 2013 are numerically equal to the intermediate life (5 year/50,000 mile) EPA or California limits; presumably to match the 80,000 km durability of the earlier Euro standards. US based standards effective from 2013 are based on the 120,000 mile full useful life limits.

New gasoline fueled vehicles must also meet an evaporative emission limit of 2 g/test (SHED).

In-use Vehicles

Early Inspection and Maintenance tests were carried out with a two speed idle test. In-use light-duty, medium-duty spark-ignition and heavy-duty gasoline fueled vehicles had to meet I/M maximum limits of 0.5% CO and 100 ppm HC. Light-duty SI vehicles must also meet a minimum limit of 6% CO2 + CO. Light-duty diesels must show no visible smoke. In 2006, an Acceleration Simulation Mode (ASM) test was introduced for SI vehicles in the RM. Medium-duty and heavy-duty diesels must pass filter smoke number and opacity tests with the engine under load and during a snap-acceleration test. An in-use opacity limit for vehicles equipped with particulate filters is set at 0.24 m-1 maximum [2949]. Urban buses have also the following in-use emission limits [2950]:

  • Smoke opacity < 4%, k = 1.0 1/m for diesel engines
  • CO < 0.5%, THC < 100 ppm for gaseous fuel and gasoline engines
