In some respects, the newer diesel engines are actually cleaner than gasoline engines, and their visible emissions are less dangerous than the invisible ones sneaking out of gas engines, according to a new study published in Scientific Reports that was carried out by Canadian, European, and U.S. scientists.
Are diesels cleaner than gasoline?
Diesel engines are cleaner than gasoline engines and alternative fuel engines as well. Diesel engines do not produce as much carbon dioxide as gasoline. They may produce more carbon dioxide than alternative fuels.
While new generation diesels emit lower levels of carbon dioxide than petrol engines, they tend to emit higher levels of NOx. In built-up urban areas, these emissions mean that diesel engines are often the biggest cause of roadside air pollution, particular among older models.

Is diesel exhaust worse than gas?
Although diesel cars obtain 25 to 35 percent better mileage and emit less carbon dioxide than similar gasoline cars, they can emit 25 to 400 times more mass of particulate black carbon and associated organic matter (“soot”) per kilometer [mile].
Why do diesels get better mpg?
According to Bell Performance and Road and Track, customers who drive many highway miles often prefer diesel engines, since they are more efficient on these roads than gas engines. Diesel fuel simply packs more energy in every gallon than gas fuel, which makes it more economical overall.

Are diesel engines harder to work on?
Diesel engines are easier to work on because components are designed with maintenance in mind. In general, diesel engines are less complicated and require less tooling. Components are usually easier to reach and therefore make replacing parts and regular maintenance simpler.
Are diesel cars going to be banned?
The sale of new petrol and diesel cars will be banned in the UK from 2030. Here’s everything you need to know. The shift to zero-emissions electric cars is gathering pace as authorities around the world act to reduce carbon emissions and tackle climate change.
