SYSTEM FOR THERMALLY INSULATING AN ENGINE

摘要

System for insulating an element of a power train (1) comprising an internal combustion engine (100) comprising: a solid mass (10; 13; 16) intended to be in thermal contact with a heat source, the solid mass being at least partially surrounded by a chamber (11; 14; 17) containing a gas and - a pump (30) for regulating the pressure of the gas, characterized in that the regulating pump is controlled as a function of a temperature in order to modify the thermal conductivity of the element between the solid mass and an environment external to the element.
