If you choose Other users you can create regular accounts just fine. However, if you need to setup time limits for some accounts, it is impossible to do so. It is a feature exclusive to Your family. Not all time-restricted users I want to create are my family, and not everyone is okay with sharing their info with Microsoft.
By this means, a catalyst is produced which is readily reduced at 300Â°C - 350Â°C (570 - 660OF) but with which loss of activity caused by sintering is not a problem during several years, normal operation at temperatures up to 350Â°C (660OF).
Depending on the application, catalyst inlet temperature is often 650 C to 850 C at the inlet to the first catalyst. It is typically controlled to a 850 C to 900 C maximum temperature, often by fuel enrichment in engines with PFI fuel systems. The limiting factor for exhaust temperatures in the past had largely been exhaust catalyst durability (sintering of active metals and metal oxides and washcoat/substrate durability).
