Definitions
- the invention relates to an internal combustion engine with a cooling water heat accumulator and an exhaust gas recirculation with cooled in an exhaust gas heat exchanger Exhaust gas and a work process that can be carried out with it.
- the components required in each case namely the cooling water heat accumulator and the Exhaust gas recirculation heat exchangers are very large-volume components, which are particularly important smaller vehicles only with a lot of design effort in an engine compartment can be housed and applied to the engine.
- Another disadvantage is that each individual component has a not negligible weight.
- the object of the invention is to provide an internal combustion engine, which with the use of a Cooling water heat storage and an exhaust gas heat exchanger even in a confined space enables. Furthermore, a more efficient working process should Internal combustion engine to be made available.
- a valve which that coming from the cooling water outlet of the internal combustion engine Cooling water flow can enter the cooling water inlet of the cooling water heat accumulator or bypasses it through the storage heat exchanger.
- the advantage of this is that the amount of water to be heated first inside Cooling circuit is significantly reduced, so that the internal combustion engine faster can approach their optimal operating temperature.
- the Valve in front of the cooling water heat accumulator of the storage heat exchanger is closed, can recirculated exhaust gas through the exhaust gas heat exchanger of the storage heat exchanger are passed through to the intake manifold and cools due to of the cold water in the storage heat exchanger, it being advantageous warmed up.
- the time from which exhaust gases are led through the cooling water heat accumulator and in what amount is preferably arranged in the exhaust gas stream Valve regulated.
- An embodiment of the inventive is also of particular importance Internal combustion engine, in which the cooling water heat accumulator of the storage heat exchanger is provided with an additional vent closure, so that it is in a third function can also serve as an expansion tank for the cooling water, so that this, as a separately executed component, can also be dispensed with and that Additional weight of the integrated cooling water heat accumulator with exhaust gas heat exchanger by saving the own weight of the expansion tank with filling, about 3 kg a small vehicle that can be fully compensated.
- the heat exchanger which is heat-insulated from the outside, before the start of the Internal combustion engine is still filled with hot cooling water from the last engine run, is immediately after starting the engine by a in front of the cooling water heat accumulator arranged valve is opened briefly and the hot cooling water in it against cold cooling water from the internal cooling circuit of the internal combustion engine exchanged, after which the valve closes and the cooling water flow through as long Bypass past the storage heat exchanger until it reaches a minimum operating temperature has reached, from which the valve the flow of cooling water through the cooling water heat accumulator of the storage heat exchanger releases again.
- the cold cooling water heats up in the cooling water heat accumulator through the recirculated exhaust gas and the cooling water in the internal cooling circuit Internal combustion engine, the temperature difference between cooling water and Exhaust gas always remains so large that the exhaust gas is cooled even when the valve is open remains guaranteed.
- a partial flow of the exhaust gas 9 is a Exhaust gas recirculation valve 14 branches off and through one in a cooling water heat accumulator 2 integrated exhaust gas heat exchanger 4 of a storage heat exchanger 1 and passed then passed through an exhaust gas recirculation line 10 to an intake manifold 15, where it is with Fresh air 8 mixed is fed back to the combustion process.
- the cooling water conveyed out of the internal combustion engine 11 flows through a Cooling water drain line 5 to a valve 3, which is in front of the cooling water heat accumulator 2 of the storage heat exchanger 1 is arranged and which the cooling water flow either through the cooling water heat accumulator 2 or via a cooling water bypass 6 bypasses the storage heat exchanger 1.
- the cooling water flows through a heating heat exchanger 16 and is then fed back to the internal combustion engine 11.
- the storage heat exchanger 1 is additionally provided with a vent lock 17 equipped so that it can also serve as a surge tank.
