Problems solved by technology

The more unstable the operation of the internal combustion engine becomes (such as in the case of alternating uphill and downhill or for vehicles in split traffic), the further the achievable efficiency of heat recovery decreases

Embodiment Construction

[0077] exist figure 1 shows as a block diagram a method for recovering heat and converting it into a drive for a motor vehicle, in particular a commercial vehicle (such as a truck or bus) with an internal combustion engine (not shown) as drive source An arrangement of the mechanical power of the system with a working medium circuit 1 into which, for example, the two evaporators 2 , 3 , the expander 4 and the condenser 5 are also integrated here.

[0078] For example, deionized water is used as the working medium, which is filled into a storage container 6 at the underside of which a delivery line 7 branches off. A supply pump 8 is arranged in the delivery line 7 , which supplies here two separate delivery lines 7 a , 7 b (which are connected on the inlet side to the evaporators 2 , 3 ) via a distributor. Furthermore, for example electrical proportional flow control valves 10 are installed in each delivery line 7 a , 7 b , by means of which the working medium mass flow and thu...

Abstract

The invention relates to a method and a device for recovering heat and converting it into mechanical power, the working medium guided in the working medium circuit using at least one evaporator integrated in the working medium circuit by means of the internal combustion engine of a motor vehicle The waste heat is evaporated, the steam produced is fed to an expander connected to the internal combustion engine, and the waste steam from the expander is subsequently led back into the liquid phase in at least one condenser. Downstream of the at least one evaporator, at least one valve and the steam accumulator are integrated into the working medium circuit in such a way that at least a portion of the steam produced is fed in, especially when the drive power of the expander is not required and / or when the internal combustion engine is not powered. into the steam accumulator, wherein the steam stored in the vapor accumulator is at least partially returned to the working medium circuit for driving the expander when the expansion machine again requires drive power and / or when the internal combustion engine is operating under power.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for recovering heat in a drive system for a motor vehicle and converting it into mechanical power, as well as a method according to the preamble of claim 9 Apparatus for performing such a method. Background technique [0002] Such methods are generally known. The structural design of the system components, in particular the evaporator, the expander (fluid machine or reciprocating piston machine) and the condenser, takes into account conventional motorway-road traffic applications (Autobahn-Fernverkehrseinsatz), ie almost steady-state operation of the internal combustion engine And in this operation it helps to increase the efficiency of the drive system. As heat carriers that can be used, for example, coolant or charge air, but in particular the exhaust gas of an internal combustion engine, can be used. The more unstable the operation of the internal combustion engine becomes (su...
