It comprises an internal-combustion engine (1), a radiator (2), a coolant liquid for the engine (1), a heat exchanger (3), and a first heat-regulation device (4) for the engine (1). It is characterized in that it comprises a single coolant liquid inlet to the heat exchanger (3) coming from the radiator (2) or from the engine (1), and a second temperature-regulation device (6), controlled by means of the oil temperature at the entry to or at the exit from the exchanger (3), allowing the oil to be heated in a forced-heating step and a natural-heating step, and the oil temperature to be regulated in order to keep it at its ideal operating temperature. The oil-temperature-regulation system is greatly simplified.
