Exhaust
Gas
Recirculation
EGR System
use heat exchange between a portion of engine exhaust gases and cooling wate
to lower the temperature of the gases, then supplies them to the combustion chamber to
decrease the production of nitrogen oxide.
Nitrogen oxide is released when fuel is burned at industrial sites or as part of automobile exhaust gases, and is usually released as air pollution in the form of nitrogen dioxide (NO2). It reacts photochemically with sunlight, producing micro-dust and ozone, and through contact with the mucous membranes of the eyes and nose, etc., it can cause chronic bronchitis, pneumonia, pneumorrhagia, and pulmonary edema. - As automobiles age, carbon sedimentation accumulates inside the cooler and the heat exchange performance of the cooler falls, causing increased emissions of nitrogen oxide.
What if the EGR systems in the approximately 1.1 million cars that are
10 years or older were replaced (based on 12-13 year old vehicles)?
The effect of planting approximately 200 million trees,
a forest of around 45,600Ha in area
The entire area of Jirisan National Park
Environmental rehabilitation expected
With an annual average of 20,000km of driving,
nitrogen oxide is reduced by 44%
The effect of planting
Approximately 196 trees per year
