IC engine and method for operating an IC engine
View Patent ↗A method is provided for operating an internal combustion engine of a motor vehicle. The method includes, but is not limited to storing exhaust gas while the engine is working, and supplying the stored exhaust gas into at least an engine cylinder during a subsequent start phase of the engine.
1. A method for operating an internal combustion engine of a motor vehicle, comprising:
storing an exhaust gas during operation of the internal combustion engine; and
supplying the exhaust gas into at least an engine cylinder during a subsequent start phase of the internal combustion engine;
receiving air via an intake conduit that is fluidly connected to the tank per the engine cylinder via an injection port, wherein the injection port leads into the intake conduit downstream a swirl valve.
2. The method according to claim 1 , further comprising regulating an engine operating parameter in order to increase the exhaust gas produced during a storage phase of the exhaust gas.
3. The method according to claim 1 , further comprising storing the exhaust gas at least during a shut off phase of the internal combustion engine.
4. An internal combustion engine of a motor vehicle, comprising:
an engine cylinder;
an EGR system;
a tank of the EGR system;
a valve of the EGR system configured to store exhaust gas into the tank during an operation of the internal combustion engine and configured to supply the exhaust gas from the tank into the engine cylinder during a subsequent start phase of the internal combustion engine;
an intake conduit that is fluidly connected to the tank per the engine cylinder via an injection port; and
a swirl valve for the intake conduit, wherein the injection port leads into the intake conduit downstream the swirl valve.
5. The internal combustion engine according to claim 4 , wherein the tank is fluidly connected to a plurality of cylinder intake conduits via a plurality of injection ports.
6. The internal combustion engine according to claim 4 , wherein the injection port comprises an On/Off electrically controlled valve located in the injection port.
7. The internal combustion engine according to claim 4 , wherein the valve comprises a one way valve located in the intake conduit.
8. The internal combustion engine according to claim 4 , further comprising a control system configured to regulate an engine operating parameter in order to increase production of the exhaust gas during the operation of the internal combustion engine.
9. The internal combustion engine according to claim 4 , further comprising a control system configured to implement an engine start and substantially stop functionality.
