What pollutes diesel or gasoline more

Say What contaminates more a diesel or a gasoline car It is difficult, since each one pollutes differently. For example, if we compare two cars with the same characteristics, with the only difference that one is diesel and the other of gasoline, we find that the diesel car emits less grams of CO2 per kilometer traveled, but also emits more components than that of gasoline.

However, with the new filtering techniques of the diesel enginesalso known as Díel, diesel or dieselthe difference is minimized. Everything is due to the new Euro 6 regulations which makes emissions from other diesel pollutants similar to those of the EURO 4 regulations of gasoline.

Therefore, today a gasoline car and a diesel one could say that they contaminate the same, but in a different way, since Gasoil cars emits less CO2 than gasoline cars, but continue to emit more of other pollutantsalthough no longer with as much difference as in previous years.

In this other article you can learn more about vehicular pollution: what is, types, causes and consequences.

We have said that CO2 is one of the main pollutants that are emitted in the combustions of the engines that use these fossil fuels but, What are the polluting gases emit diesel engines and gasoline engines?

Pollutant gases emitting diesel cars

• Nitrogen
• CO2
• Water
• Oxygen
• Sulfur dioxide
• Soot
• Hydrocarbons
• Nitric oxides
• Carbon monoxide

Polluting gases emitting gasoline cars

• Nitrogen
• CO2
• Water
• Hydrocarbons
• Nitric oxides
• Carbon monoxides

As for the car contamination that uses gasolinewe can say that the most significant differences between diesel and gasoline engines are based on the way the fuel is mixed with air and how they enter into combustion. They have different functioning, but it is not a better than the other.

So, How does gasoline affect the environment? This causes greenhouse gases to the atmosphere, such as CO2. For each liter consumed of gasoline are emitted 2.32 kg of CO2 To travel about 13 km.

With the subject of the gasoline engine something clearer, we clarify some doubts related to diesel. How does diesel affect the environment? How much does a liter of diesel pollute?

The answer is that diesel or diesel negatively affects the environment and does so at levels very similar to gasoline. In addition to CO2, diesel also emits other gases and particles harmful to the environment, such as SO2, Nox and soot. For every liter, the diesel emits 2.6 kg of CO2 For about 16 km.

There are different devices that have been incorporated into the car industry with the objective of reduce pollution issued by vehicles:

• Adblue: It is an additive formed mainly based on urea and is injected into the exhaust gases, it is injected before these gases reach the catalyst. The urea contains ammonia and thanks to this and the high temperatures of the catalyst, when reacting the NOX N2, CO2 and water vapor occurs.
• Catalyst: The objective of this device is to reduce those harmful agents that the escape through catalytic reactions (oxidation-reduction).
• NOx catalyst-accumulator: As the name implies, they are NOx accumulative catalysts, they accumulate the NOX until it is regenerated and then eliminated. It arises to complement when catalyzing three ways.
• Antiparticle filter: It serves to retain the soot particles that occur during diesel combustion, to later eliminate them through the oxidation of them.
• EGR gas recirculation: This device manages to reduce approximately 50% of NOX emissions since it recirculated exhaust gases to the intake manifold when the engine works at partial load and operating temperature.

It is clear that others fossil fuels They contaminate the environment a lot, both its extraction and its use in combustion. Nevertheless, oil and its derivatives They are the best known for offering great advances in technology, transport and many other areas, but also for the high pollution they produce. How we have already mentioned Both gasoline and diesel or dieselboth derived from oil, contaminate the environment a lot, being both equally harmful.

Therefore, you have to make moderate use of vehicles of this type and opt for public transport or electric vehicles or, at least, for hybrids.

We encourage you to also read this other article about what fossil fuels are and how they formed.

There are many cars models that are increasingly efficient for reduce vehicular pollution. These are some of cars that pollute less:

• Toyota Prius 1.5 Hybrid
• Volvo V70 2.4 Bifuel
• Honda Civic 1.3i Hybrid
• Skoda Octavia Combi
• Skoda Octavia 1.6
