Diesel Engines Emit More Pollutants Than Petrol, Here's Why

Imagine two types of car engines: one runs on diesel and the other on petrol.

The diesel engine is like a very strong person who squeezes the air super tight, making it really hot.

When the diesel fuel is added, it burns, but this burning makes more harmful smoke like tiny bits of soot (called Particulate Matter) and a gas called Nitrogen Oxides.

The petrol engine is more like a controlled firework; it uses a spark to burn its fuel more evenly.

Because diesel burns differently, it releases more of these bad pollutants that can make it hard to breathe and harm the environment.

Also, diesel fuel itself has more stuff in it, like sulfur, that can make even more pollution.

This is why diesel cars are becoming less common, especially for smaller vehicles, as rules get stricter about keeping our air clean.
