From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Emitec catalyst for SCR NOx reduction

Diesel engines for commercial vehicle applications often operate under ignition pressures in excess of 200 bar (2900 psi)—250 bar (3625 psi) and higher are future possibilities—for optimal fuel consumption. Such high pressures lead to very high combustion chamber temperatures, which lead to oxides of nitrogen (NOx) generation. Engineers have learned to reduce NOx emissions by internal engine measures such as increasing the fuel injection pressure, using multiple injections, exhaust gas recirculation (EGR), etc. However, NOx must be reduced even further to comply with more stringent regulations in Europe, the U.S., and Japan. For that reason, there are many aftertreatment projects under way throughout the industry, including De-NOx systems from Emitec that are presently being developed and introduced for Mercedes-Benz trucks in Germany.
