Operating method for internal-combustion engine, involves examining fail-safe condition, and switching normal operation in fail-safe operation with operational behavior of internal-combustion engine

摘要

The operating method involves examining a fail-safe condition, and switching a normal operation in a fail-safe operation with an operational behavior of an internal-combustion engine (1) if the fail-safe condition is fulfilled. The operational behavior of the internal-combustion engine is monitored in the fail-safe operation by a sensor (8). An independent claim is included for an engine controller for an internal-combustion engine, which has a program memory.
