Y27 EGR switchover valve

Exhaust gas is recirculated as a function of the map in the engine control unit as soon as the following criteria are met:

Coolant temperature >48 °C

Engine speed <3500 rpm

Part throttle

The EGR switchover valve (Y27) is actuated at the ground end and switches vacuum to the EGR valve, as a result of which this valve is opened.

-----------------------------------------------------------------------------------------

Low-oxygen exhaust is inducted dependent on the position of the throttle valve. As a result, the fuel/air mixture contains less oxygen.

This results in a reduction in the combustion temperature and the formation of NOx is reduced.
