Abstract: The invention relates to a method for detecting an unsealed location in a heat recovery system (5) of an internal combustion engine (1) of a motor vehicle. The heat recovery system (5) has at least one combustible working medium, a working medium circuit (6) with at least one EGR evaporator (7), a pump (8), and at least one expansion machine (9). The aim of the invention is to allow an early and reliable detection of leakages in the EGR evaporator (7) of a heat recovery system (5) in the simplest manner possible. This is achieved in that the internal combustion engine (1) is operated in the overrun mode, the oxygen concentration in the exhaust gas is ascertained and compared with a defined lower threshold, and if the lower threshold is undershot, a leakage in the EGR evaporator (7) is detected.

Abstract: The invention relates to a method for controlling a waste-heat utilization system (20) for a motor vehicle driven by an internal combustion engine (10) by means of a drive train (13), wherein the waste-heat utilization system (20) has at least one expander (22), at least one evaporator (21), and at least one pump (24) for an operating medium, in particular ethanol. At least the evaporator (21) is arranged in the region of the exhaust gas system (11) of the internal combustion engine (10). The expander (22), which can be operated in several operating modes, performs work in at least one operating mode.

Abstract: A method for detecting a leaking point in a heat recovery system of an internal combustion engine of a motor vehicle, wherein the heat recovery system includes a combustible working medium and a working medium circuit with an evaporator, a pump and an expansion machine. The recirculated exhaust gas of the engine flows through or around the evaporator which is arranged in an exhaust-gas return line. At least one oxidation catalytic converter is arranged in an exhaust gas line of the engine. A first temperature sensor is arranged in the exhaust gas line upstream and a second exhaust gas temperature sensor is arranged downstream of the oxidation catalytic converter. Temperatures of the exhaust gas are measured with these temperature sensors during operation of the engine in the exhaust gas line upstream and downstream of the oxidation catalytic converter.

Abstract: System for managing a vehicle compressor, wherein the compressor (C) is driven in rotation by a vehicle engine (E). The system varies a stop pressure threshold (cut-off threshold) of the compressor as an inverse function of a compressor speed of rotation. The compressor speed of rotation is directly proportional to the vehicle engine speed of rotation (E).
