Abstract
The invention relates to a method for detecting an unsealed location in a heat recovery system of an internal combustion engine of a motor vehicle. The heat recovery system has at least one working medium, in particular a combustible working medium, and a working medium circuit with at least one evaporator, a pump, and at least one expansion machine to allow an early and reliable detection of leakages in the evaporator.
