General information
The EATS to comply with the emissions standards Euro V or EEV
based on new engine technology in combination with a range of
measures to reduce the emissions in exhaust.
The emissions standard Euro V, EEV
Emissions standard are legal guidelines which serve to subdivide
vehicles into certain emissions classes. These emissions classes are
assigned to certain emission

numbers
which serve, amongst other things, to compute the vehicle tax
and classification in emission groups for environmental zones.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The emissions standards Euro V and EEV for commercial vehicles
establish very strict limits for output of carbon monoxide (CO),
nitrogen oxide (NOx), hydrocarbons (HC) and particles (PM).
As a vehicle manufacturer Mercedes

Benz must guarantee
compliance with these limits for an established time period and
mileage. Therefore the EATS is a component of engine/vehicle
homologation subject to compulsory certification.

New diesel engine generation
The new engine generation is fitted with a common rail diesel
injection system, EGR and boost pressure control. The engines
themselves are set to maximum efficiency and low particulate
emissions.
