Method and device for controlling an internal combustion engine

摘要

In a method for stopping an internal combustion engine, a quantity of air supplied to the internal combustion engine via an air-metering device, e.g., a throttle valve, is reduced after a stop request has been determined, and the quantity of air supplied to the internal combustion engine via the air-metering device is increased again when a detected speed of the internal combustion engine falls below a predefinable speed threshold value. The predefinable speed threshold value is increased when, after the metered quantity of air is increased up to stopping of the internal combustion engine, an intake cylinder no longer passes through a bottom dead center.

1. A method for controlling an internal combustion engine, comprising:
reducing a quantity of air supplied to the internal combustion engine via an air-metering device after a stop request for stopping the engine has been detected; and subsequently increasing the quantity of air supplied to the internal combustion engine via the air-metering device when a detected speed of the internal combustion engine falls below a predefined speed threshold value; wherein the predefined speed threshold value is increased when, after the metered quantity of air is increased up to stopping of the internal combustion engine, an intake cylinder no longer passes through a bottom dead center, wherein the intake cylinder is a cylinder of the internal combustion engine that is in an intake stroke one of immediately after or during the increase of the quantity of air supplied to the internal combustion engine; and wherein the speed threshold value is reduced when, after the metered quantity of air is increased up to stopping of the internal combustion engine, the intake cylinder goes into a power stroke.
