We all know that Diesel engines are much more pollutant than gasoline ones, and measures had to be taken.
Since 2006, new cars equipped with Diesel engines (especially in Europe) had particulate filters.
Now, let’s get a little bit in depth.
Every car has a catalytic converter, a device which contains platinum and other rare metals which absorb (even destroy) most of the harmful pollutants. In Diesel engines, besides these pollutants there are fine particles from 2.5 to 10 microns which are extremely harmful to our health. If we inhale those particles, they remain stuck forever on our lungs which cause fatal injuries and in some cases, even cancer.
To reduce the amount of particles which come from Diesel engines, engineers have created the particulate filter – a device which absorbs particles with the diameter greater than 2.5 microns.
Also, Diesel engines with particulate filters emit less smoke.
The sad part with particulate filter is that they break pretty fast and they’re expensive. Whenever the particulate filter is stuck or needs regeneration, you need to drive 10-20 km constantly at 3,000 rpm and it will get at its standard state.
Driving such cars around the city for short distances will damage the particulate filter in less than 500 miles, and one particulate filter costs from $800 to $3,000 depending on the car and manufacturer.
That’s why I prefer gasoline…
