The petrol generator produced around five times as many ultrafine particles.
The Danish Technological Institute measured ultrafine particle emissions from both generators. Both produced ultrafine particles. But the difference between them was surprising.
In this particular test, the petrol generator produced around five times as many ultrafine particles as the diesel generator tested.
“I did not expect the petrol generator to produce around five times as many.”
Søren Hanghøj Møller, Danish Technological Institute.
The measurement relates to these specific generators and test conditions, so it should not be read as a general comparison between all petrol and diesel generators.
What it does highlight is useful in itself: actual emissions may not always match our assumptions.
