please explain the best position of catalyst placement in 6 element catalyst housing with 3 catalyst

Does inlet temperature at the catalyst face effect the catalyst efficiency? Is there an optimal temperature for effectiveness? A temperature that will degrade the element?

Could you explain the difference between radial & Lateral catalyst elements? One more efficient than the other?

I've noticed more inquiries in Eastern Europe for emissions reductions. Is that something that Emit is preparing for? Is there any particular law we need to look out for?

How do Catalyst elements and blanks effect back pressure?

How often do elements typically need to be cleaned? If elements are not cleaned do they "clog" the exhaust? Finally are elements removed to be cleaned and sent to EMIT or can they be cleaned in the field?

Is a 3 way catalyst / oxidation catalyst / Diesel Catalyst just compromised of different precious metals to meet specification emissions?

The EA housing has the capacity for 2 catalyst elements. In the situation where only one is needed why is it recommended to place in the space furthest from the inlet?

better understanding how a catalyst works and how it is made.
