When you pit liquid into them which is a bad thing since liquid solifies the ash, you will not get it in the air, only in the place you are cleaning it in
DPF was introduced prior to the SCR system. Also, you have to actually be running pretty good when regen happens for it to work but for school buses, they don't get the engine speed/load needed in order for regen to work.
Because diesels vehicles with dpf's need to do long journeys for the soot to get hot enough and burn which is known as regenerating. If your engine is idling or start stop like buses and taxi's the soot doesn't get hot enough to get burn't off it just gets trapped in the dpf and clog it up.
Particulate emissions don't contribute to climate change. They are dangerous to human health and cause great harm to children and people with asthma and emphysema.
what a piece of shitty technology all a diesel needs is Variable geometry turbo with a really good tune and it won't blow an ounce of smoke out the pipes.
Why can't he say the word "PROCESS" properly?…. in reality he just puts it in a kiln and then takes it out the next day. It heats up and cools down. The "Particulant filter cleaning machine" is just a sandblasting machine box… I bought a new one for £100 recently. You just use the compressed air from it… nothing difficult and no magic ! So this should be a £50 job each time - it is so easy.
He's using the American pronunciation. And that's not a Sandblasting box, it's specifically designed for cleaning DPF's, which is why it has a Vaccuum unit at the bottom along with a collection box for waste and a plate specifically designed to seat the DPF - He doesn't state that it's anything super secret he even says it uses a simple high pressure air knife to blow ash through the filter - but it does work in combination with the vaccuum under the DPF...
