How to Deal with Car Emissions Effectively, Good for the Environment

Automobile exhaust contains toxic components such as HC, Nox, Co... not only affecting human health but also adversely affecting the environmental ecosystem, air pollution, and weather changes. instability, greenhouse effect…

Along with the constant increase in the number of cars in operation, automobile emissions are also greater. How to effectively handle automobile exhaust, avoiding negative impacts on people and the living environment? Let's find out through the article below!

Learn About Car Emissions

When a car is running, the internal combustion engine produces waste products including CFCs, Pb, Hc, NOx, CO2, CO and sulfur compounds. After automobile waste is released into the environment, it is likely to be separated and synthesized to form many compounds that are harmful to human health and change the climate and ecological environment.

Based on the influence of components, emissions are classified into the following 2 groups:

• Substances present in the exhaust gas that cause common pollution include NOx, CO, HC, PM and CO2 particulate matter.
• Substances present in the exhaust gas that cause typical pollutants include polynuclear aromatic hydrocarbons – PAH, aldehydes, formaldehyde, buta-l… Although these substances account for only a very small percentage, they cause unpredictable consequences such as changes. genes, cancer...

How to Treat Car Exhaust Effectively

The process of treating automobile exhaust gases is divided into 4 groups:

The first group – Reducing pollution caused by substances such as HC, CO, NOx at the cylinder

In order to reduce harmful emissions including NOx, CO, HC, it is necessary to optimize the engine system structure affecting the combustion process such as:

• For direct injection or diesel engines, it is necessary to design the engine cover and piston to form a cyclone effect to help the process of mixing fuel and air better, and the fuel combustion time is faster.
• Increase the intake efficiency by expanding the valve size, using the turbocharger system.
• Design a reasonable early discharge valve opening time.
• Application of electronic control fuel injection system, single or multi-point injection, increased injection pressure...

The second group – Treatable when released into the environment

The content of harmful substances in the exhaust gas of automobiles before being discharged directly into the environment must ensure the correct dosage according to the permitted regulations. Some common waste treatment technologies today include:

• Accumulator NOx processor.
• Oxidation treatment for diesel engines.
• PM filter.
• 3-way catalytic converter.

The third group – Application of the backend system

In order to avoid overloading the engine in some working modes and promote the effectiveness of the above groups of automotive emission treatment solutions, car manufacturers combine the use of ancillary systems including:

• OBD Self-Diagnostic System.
• Air injection system.
• The system ensures the intake air temperature.
• Exhaust gas return control system.
• ...

Fourth group – Fuel handling

Fuel has a great impact on exhaust gas characteristics, the possibility of exhaust pollution of internal combustion engines. Common methods of limiting automobile exhaust pollution include:

• Using green materials to limit harmful emissions into the environment.
• Choose the right fuel for your vehicle's engine.
• Increase fuel quality by reducing harmful additives and impurities…

Measures to Reduce Car Emissions Into the Environment

To minimize car emissions into the environment, vehicle owners can refer to the following ways:

• Periodic cleaning and change car engine air filter Avoid dust accumulation that causes machine blockage.
• Tor periodic lubricant helps cars create less smoke and emissions.
• Make sure your tire pressure is correct by checking it regularly. Low pressure car tires cause great obstacles, the engine needs more fuel to operate the car normally, thus increasing emissions into the environment.
• Carrying the correct vehicle weight to ensure that the vehicle operates at the correct capacity and reasonable fuel consumption. Overloading causes the vehicle to operate continuously with high capacity, consumes a lot of fuel and generates large emissions. In addition, overloading is also very dangerous because it increases the possibility of tire explosion.
• Prioritize the use of cars that are low on fuel consumption and environmentally friendly.
