  • Method and devices for operating an internal combustion engine having a supercharging system
    Patent number: 11396842
    Abstract: A method and device for operating an internal combustion engine having a supercharging system that has an exhaust turbocharger and an electrically driven compressor. An output of the exhaust turbocharger is adjustable by a control element. A boost pressure setpoint is determined for achieving an increased engine torque setpoint. The supercharging system is adjusted to build up the actual boost pressure in accordance with the boost pressure setpoint and a positive scavenging gradient in a cylinder of the internal combustion engine is adjusted as the overriding command variable for driving the supercharging system.

  • Method for operating an internal combustion engine, control unit, and electrically driven charging device
    Patent number: 11168607
    Abstract: A method for operating an internal combustion engine with a system for supercharging that includes an exhaust turbocharger and an electrically driven charging device for dynamic assistance during build-up of boost pressure, with: determining a drive criterion of the charging device, establishing an initial quantity of the drive criterion; continuously determining a reduction factor for the drive criterion within a balance period; applying the reduction factor to the initial quantity of the drive criterion; and operating the charging device with the drive criterion reduced by the reduction factor.
