In a method for controlling the heat in an internal combustion engine for a vehicle with a coolant circuit and actuable devices for influencing the heat balance of the internal combustion engine, wherein a coolant temperature and further operating parameters of the internal combustion engine are recorded, the actuable devices are operated as a function of the coolant temperature and the further operating parameters of the internal combustion engine in such a manner that an output value for determining a control variable is provided by means of a basic characteristic diagram as a function of the rotational speed and the load on the internal combustion engine, and this control value is corrected by means of a controller as a function of the coolant temperature and/or the further operating parameters.

Method for controlling the heat in an automotive internal combustion engine

An internal combustion engine having one or more parallel exhaust-driven turbochargers that each comprise an activatable delivery capacity adjusting unit for variable adjustment of the boost air delivery capacity with malfunction monitoring of each individual delivery capacity adjusting unit wherein, upon detection of a malfunction of a respective delivery capacity adjusting unit, a corresponding malfunction datum is emitted.
