Abstract (en)

[origin: EP2392794A1] The engine (1) has a cylinder block coolant jacket operated in a turbine housing (13) in a turbocharger (12) during a subphase of a heating phase of the engine according to nitrogen oxide flow strategy. A cooling circuit (4) is separated from the cylinder block coolant jacket and connected with a common pump (7) that is joined to the cylinder block coolant jacket. A bypass (11) is provided downstream to the pump and upstream to a cylinder block coolant inlet (9). The housing is made of light material i.e. aluminum, where the housing or the turbocharger is provided with the cooling circuit. An independent claim is also included for a method for controlling coolant during a heating phase of an internal combustion engine.
