    Nameplates, model designation or serial number can be found on the product. All EU-certified engines delivered by MTU come with a second nameplate. This second nameplate is deliv- ered "loosely" with the engine. If the nameplate secured to the engine after installation in the vehicle/system is not visible without the removal of components, the system integrator must install the second nameplate in a clearly visible area on the vehicle/system.
  • Page 7 Replacing components with emission labels On all MTU engines fitted with emission labels, these labels must remain on the engine throughout its opera- tional life. Exception: Engines used exclusively in land-based, military applications other than by US government agen- cies.
