Charge air temperature regulating method for internal-combustion engine, involves determining control signal for pressurization of engine characteristic thermostatic valve from reference-bypass-coolant flow and determining position of valve

摘要

The method involves determining a charge air temperature over a temperature of an inter heat exchanger coolant flow (9). An offset is computed from a reference charge air temperature to an actual load air temperature. A reference bypass coolant flow is computed as a correcting variable from the offset over a charge air temperature controller. A control signal is determined for pressurization of an engine characteristic thermostatic valve (6) from the reference-bypass-coolant flow. A position of the engine characteristic thermostatic valve is determined over the control signal.
