SCR Technology and Engine Emissions

The emission of certain gases and toxic chemicals can be particularly damaging to the environment and can have some grave health affects for humans. In order to combat the amount of emissions produced by engines, Selective Catalytic Reduction (SCR) Technology has been created. SCR technology works to limit the amount of toxic emissions created and pushed into the environment by car exhaust.

What Is SCR Technology?

In short, SCR technology converts gaseous emissions into water, carbon dioxide and nitrogen to be released into the air, effectively minimizing air pollution. SCR engine emissions are not damaging to the environment as nitrogen makes up about 70% of breathable air and water vapor will go on to create condensation.

In more complex terms, SCR technology first removes particulates from the exhaust in order to prepare it to be converted. Then, the exhaust is then combined with Diesel Exhaust Fluid (DEF). This causes a chemical reaction which converts the exhaust into water, carbon dioxide and nitrogen.

Why SCR?

As aforementioned, SCR engines can reduce the number of toxic emissions that are released into the environment. In addition to releasing hydrocarbons and nitrogen oxides into the air, cars also release carbon monoxide. If areas are not properly ventilated carbon monoxide can cause poisoning and even death. SCR Technology can reduce these emissions and therefore reduces health risks that come with operating a motor vehicle.

In order to ensure that the SCR technology continues to operate at full capacity the vehicle operator needs to maintain the amount of DEF in the SCR system. This is as simple as maintaining the amount of engine oil or transmission fluid in a vehicle. If the amount of DEF starts to get low, the driver will be signaled using the indicators on the dashboard. If the amount of DEF becomes so low that they SCR system cannot properly operate, the car may be locked, preventing driving completely. As long as the operator of the vehicle maintains the level of DEF in the SCR system, upkeep will be very easy.

If the number of SCR systems increased along with SCR engine emissions, it could have a very positive impact on the environment. A small increase in carbon monoxide can benefit plants and reciprocally boost the production of oxygen. Similarly, the increase of water in the atmosphere can create the opportunity to create more oxygen and the creation of water vapor helps to keep the earth heated, as it is a secondary source of warmth.
