Diesel cars emit more nitrogen oxides and fine particulate pollution than petrol cars.

Is it true that Diesel cars emit more nitrogen oxides and fine particulate pollution than petrol cars?

Unclear. Two peer-reviewed sources indicate diesel cars emit more nitrogen oxides than petrol cars, one giving real-world Indian measurements and one stating diesels produce more nitrogen oxides than gasoline engines. None of the placed sources compares fine particulate emissions between diesel and petrol cars, so the particulate half of the claim is not covered.
