Method for charge pressure control of an internal combustion engine with turbines arranged in parallel, and internal combustion engine for carrying out such a method
Embodiments for controlling boost pressure during transient conditions are disclosed. In one example, a method includes, responsive to deactivation of a first turbine of a first turbocharger, deactivating an exhaust valve of a cylinder to flow exhaust gas from the cylinder to a second turbine of a s...

Summary: | Embodiments for controlling boost pressure during transient conditions are disclosed. In one example, a method includes, responsive to deactivation of a first turbine of a first turbocharger, deactivating an exhaust valve of a cylinder to flow exhaust gas from the cylinder to a second turbine of a second turbocharger, and adjusting a speed of the second turbocharger via an electric machine coupled to the second turbocharger in a generator mode; and responsive to activation of the first turbine, activating the exhaust valve to flow exhaust gas from the cylinder to the first turbine and the second turbine, and adjusting the speed of the second turbocharger via the electric machine in an auxiliary drive mode. |
