Discover why diesel fuel emits more harmful pollutants than petrol, affecting health and the environment despite its fuel efficiency.
360 views
Diesel is considered worse than petrol primarily due to its higher emissions of particulate matter and nitrogen oxides, which are harmful to both the environment and human health. These pollutants can lead to respiratory issues, smog, and acid rain. Diesel engines, while more fuel-efficient, emit more CO2 per liter of fuel burned compared to petrol engines. However, advancements in diesel technology are helping to reduce these emissions, making modern diesel engines cleaner than their predecessors.
