Jakarta, CNN Indonesia — Indonesia implemented Euro 4 emission standards to reduce pollution levels. Several countries have adopted Euro 5 and even Euro 6 emission standards.
The higher emission standards for motorized vehicles aim to reduce the negative impact of vehicles on the environment and human life, especially in big cities like Jakarta.
President Joko Widodo previously expressed his desire to increase emission standards to Euro 5, especially in the Jabodetabek area.
Currently, vehicle emission standards in Indonesia vary. For example, motorbikes are still subject to Euro 3 standards since it was first implemented in August 2013. Then petrol cars are Euro 4 starting in 2018 and diesel cars, including commercial vehicles, will enter Euro 4 in 2022.
The following is an explanation of Euro emission standards.
In an effort to reduce emissions, the European Union (EU) is taking steps to use more environmentally friendly transportation technology.
In the early 1990s, the EU issued regulations requiring the use of catalysts for petrol cars, often called the Euro 1 standard. This aims to reduce the levels of pollutants produced by motorized vehicles. Then the EU gradually tightened the regulations to Euro 2 (1996), Euro 3 (2000), Euro 4 (2005), Euro 5 (2009) and Euro 6 (2014) standards.
The same requirements also apply to diesel cars and small and large commercial cars. European motor vehicle emission standards were then adopted by several countries in the world.
Euro 4
Referring to these standards, Indonesia is at the highest level at Euro 4. This standard makes a significant reduction in the emission limits for particulates and nitrogen oxides in diesel and gasoline engines.
Euro 4 petrol emission limits:
CO: 1.00 g/km
HC: 0.10g/km
NOx: 0.08 g/km
Diesel Euro 4 emissions limits:
CO: 0.50 g/km
HC + NOx: 0.30 g/km
NOx: 0.25 g/km
PM: 0.025 g/km
Euro-5
Stricter emission limits are contained in Euro 5 which applies to petrol and diesel engine vehicles.
Euro 5 petrol emission limits:
CO: 1.00 g/km
HC: 0.10g/km
NOx: 0.06 g/km
PM: 0.005 g/km
Diesel Euro 5 emissions limits:
CO: 0.50 g/km
HC+NOx: 0.23 g/km
NOx: 0.18 g/km
PM: 0.005 g/km
PM: 6.0×10^11/km
Euro-6
Further, a reduction of up to 67 percent in permitted nitrogen oxide levels in diesel fuel and the introduction of particulate count limits for petrol at Euro 6.
Carmakers are said to be using two methods to meet diesel limits in Euro-6.
First, through selective catalytic reduction, which involves a liquid that converts nitrogen oxide into water and nitrogen that is sprayed into the car’s exhaust.
Second, an exhaust gas recirculation system is installed to replace some of the exhaust gas to reduce the amount of nitrogen that can be converted to NOx.
Euro 6 petrol emission limits:
CO: 1.00 g/km
HC: 0.10g/km
NOx: 0.06 g/km
PM: 0.005 g/km
PM: 6.0×10^11/km
Diesel Euro 6 emissions limits:
CO: 0.50 g/km
HC+NOx: 0.17 g/km
NOx: 0.08 g/km
PM: 0.005 g/km
PM: 6.0×10^11/km
