Both diesel and gasoline, fuels used for the operation of vehicles and machinery, have a strong impact on the environment due to the gas emissions that are produced when these are burned, some being more polluting than others. However, more and more environmentally friendly technologies are being developed, for example in the automotive industry they are betting on plug-in and electric hybrid cars to reduce the emission of polluting gases.
If you want to know what polluting gases are emitted by diesel engines and gasoline engines or how the burning of fossil fuels affects the environment, continue reading this interesting AgroCorrn article in which these doubts will be clarified and it will be explained in detail what pollutes the most the diesel or gasoline .

What pollutes more a diesel car or a gasoline car
Saying what pollutes a diesel car or a gasoline car more is difficult, since each pollutes differently. For example, if we compare two cars with the same characteristics, with the only difference that one is diesel and the other gasoline, we find that the diesel car emits fewer grams of CO2 per kilometer traveled, but also emits more harmful components than the gasoline one.
However, with the new filter techniques of diesel engines , also known as diesel, diesel or diesel , the difference is minimized. Everything is due to the new Euro 6 regulation that makes the emissions of the rest of diesel pollutants similar to those of the Euro 4 regulation of gasoline .
Therefore, today a gasoline car and a diesel car could be said to pollute the same thing, but in a different way, since diesel cars emit less CO2 than gasoline cars, but they still emit more others. pollutants , although no longer with as much difference as in previous years.
In this other article you can learn more about vehicular pollution: what it is, types, causes and consequences .
What polluting gases do diesel engines and gasoline engines emit?
We have said that CO2 is one of the main pollutants emitted in the combustion of engines that use these fossil fuels, but what are the polluting gases emitted by diesel engines and gasoline engines?
Pollutant gases emitted by diesel cars
- Sulfur dioxide
- Nitric oxides
- Carbon monoxide
Pollutant gases emitted by gasoline cars
- Nitric oxides
- Carbon monoxides
Here we tell you more about what type of pollution emits the exhaust pipe of a car .
How much a gasoline car pollutes
Regarding the pollution of the car that uses gasoline , we can say that the most significant differences between diesel and gasoline engines are based on the way in which the fuel mixes with the air and how they burn. They work differently, but one is not better than the other.
So how does gasoline affect the environment? This causes greenhouse gases to be emitted into the atmosphere, such as CO2. For every liter of gasoline consumed, 2.32 kg of CO2 are emitted to travel about 13 km.
How much a diesel car pollutes
With the subject of the gasoline engine somewhat clearer, we will 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 that are harmful to the environment, such as SO2, NOx and soot. For each liter, diesel emits 2.6 Kg of CO2 for about 16 km.
Devices to reduce pollution from vehicles
There are different devices that have been incorporated into the automotive industry with the aim of reducing the pollution emitted 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. Urea contains ammonia and thanks to this and the high temperatures of the catalyst, when the NOx reacts, N2, CO2 and water vapor are produced.
- Catalyst: the objective of this device is to reduce those harmful agents that escape through catalytic reactions (oxidation-reduction).
- NOx accumulator-catalyst: as their name indicates, they are NOx accumulator catalysts, they accumulate NOx until it is regenerated and then eliminated. It arises to complement the three-way catalyzing.
- Anti-particulate filter: used to retain the soot particles that are produced during diesel combustion, to later eliminate them through their oxidation.
- EGR gas recirculation: this device manages to reduce NOx emissions by approximately 50% as it recirculates exhaust gases to the intake manifold when the engine works at part load and at operating temperature.
What is the fossil fuel that pollutes the environment the most
It is clear that other fossil fuels pollute the environment a lot, both their extraction and their use in combustion. However, oil and its derivatives are among the best known for offering us great advances in technology, transport and many other areas, but also for the high pollution they produce. As we have already mentioned, both gasoline and diesel oil , both derived from oil, pollute the environment a lot, both being equally harmful .
Therefore, it is necessary to make a moderate use of vehicles of this type and opt for public transport or electric vehicles or, at least, hybrids.

Cars that pollute the least
There are many car models that are becoming more efficient in reducing vehicle pollution . These are some of the cars that pollute the least :
- Toyota Prius 1.5 Hybrid
- Volvo V70 2.4 Bifuel
- Honda Civic 1.3i Hybrid
- Skoda Octavia Combi
- Skoda Octavia 1.6
