Abstract
An exhaust gas recirculation system is provided that includes an internal combustion engine, which is supplied with exhaust gas, diverted at a removal point and returned via a return point and/or charge air, having a heat exchanger arranged between the removal point and the return point, for the returned exhaust gas and/or the charge air, and having an exhaust gas recirculation valve, by means of which the amount of returned exhaust gas and/or charge air can be regulated. To provide an exhaust gas recirculation system, which has a simple structure and can be manufactured cost-effectively, the exhaust gas recirculation valve is connectable between the removal point and the heat exchanger.
Claims17
An exhaust gas recirculation system comprising:
- an internal combustion engine that is configured to be supplied with exhaust gas and/or charge air diverted at a removal point and returned via a return point;
- a heat exchanger arranged between the removal point and the return point for the returned exhaust gas and/or the charge air;
- and
- an exhaust gas recirculation valve via which the amount of returned exhaust gas and/or charge air is regulated,
- wherein the exhaust gas recirculation valve is connectable between the removal point and the heat exchanger, and
- wherein an additional removal point, which is connectable via another exhaust gas recirculation valve to an additional return point, which is provided between the return point and the internal combustion engine, is arranged between the internal combustion engine and the removal point.
An exhaust gas recirculation system comprising:
- an internal combustion engine that is configured to be supplied with exhaust gas and/or charge air diverted at a first removal point and returned via a first return point;
- a heat exchanger arranged between the first removal point and the first return point for the returned exhaust gas and/or the charge air;
- an exhaust gas recirculation valve connected between the first removal point and the first heat exchanger;
- and
- a second exhaust gas recirculation valve connected between a second removal point and a second return point, the second removal point arranged between the internal combustion engine and the first removal point and the second return point arranged between the first return point and the internal combustion engine.
