A device is provided for compressor and charge air cooler protection in an internal combustion engine, such as a Diesel engine. The engine having an intake manifold and an exhaust manifold, first and second EGR routes, a charge air cooler, a turbocharger having a compressor and a turbine. A regulator is also provided for regulating the flow rate of exhaust gas and the splitting of exhaust gas between the first and second EGR route. A temperature sensor is also provided for sensing output temperature of gas at the outlet of said compressor. A method and computer readable medium embodying a computer program product are also provided that have a first phase of monitoring a parameter representative of the gas temperature at the output of the compressor and a second phase in which an activity involving engine components operation is performed. The activity is performed using temperature information determined in the monitoring phase.
