  • Method and device for controlling an engine
    Patent number: 6827070
    Abstract: A method and a device for controlling an engine, in which a control module calculates a setpoint torque based on an accelerator position and calculates an air mass and a fuel mass from this setpoint torque. In the process, a setpoint value for lambda (ratio of air mass to fuel mass) is taken into account when the fuel mass is calculated. A monitoring module calculates a monitoring value for the air mass from the fuel mass and compares it to a measured air mass for fault detection.
