Abstract:
The invention pertains to a method to make more efficient the engine operation in a motor vehicle, comprising the steps (s410; s420; s430) to continuously determine one or several of the parameters exhaust temperature (Texh), coolant (Tcool) and oil temperature (Toil); - to continuously determine (s440) a change in at least one of said temperatures (Texh; Tcool; Toil), as a basis for control of the heat development of said engine (s240), and - to control (s450) said heat development to achieve a desired operating mode in said engine. The invention also pertains to a computer program product comprising program code (P) for a computer (200; 210), to implement a method according to the invention. The invention also pertains to a device to make the engine operation more efficient in a motor vehicle (100), and a motor vehicle which is equipped with said device.
