Embodiment Construction

[0018] In the following, the procedure according to the invention will be described using the example of a control valve and an exhaust gas recirculation valve. In principle, the approach according to the invention is suitable for all regulators which can influence the fresh air flow or the exhaust gas recirculation flow. Instead of the fresh air flow or the exhaust gas recirculation flow, other parameter values ​​corresponding to these quantities can also be adjusted and / or controlled. That is to say the parameter value that is involved in the target value or actual value and characterizes the fresh air flow or the exhaust gas recirculation flow. Appropriate parameter values ​​for the corresponding controller control are contained in the control parameters.

[0019] The procedure according to the invention will be described below on the example of a diesel internal combustion engine. But the present invention is not limited to the application on the diesel internal combusti...

Abstract

The invention provides a method and a device of controlling the internal combustion engine. A first regulator is used to regulate the supply of fresh air into the internal combustion engine. A second regulator is used to regulate the recirculating mass of the exhaust gas. Through comparing a first rating and the real value of the fresh air flow, the value of the first adjustment parameter of the first regulator can be predetermined; and through comparing a second rating and the real value of the exhaust flow, the value of the second adjustment parameter of the second regulator can be predetermined.

Description

technical field [0001] The present invention relates to a method and a device for controlling an internal combustion engine. Background technique [0002] A method and a device for controlling an internal combustion engine are known, for example, from DE19620039. In the system described in this document, a first regulator is used to influence the fresh air flow to the internal combustion engine, while a second regulator is used to influence the exhaust gas recirculation flow. In particular, a regulating valve arranged in the intake line downstream of the compressor is used as the first regulator. An exhaust gas recirculation valve arranged in the exhaust gas recirculation line is used as a second regulator. [0003] Under certain operating conditions, not only the fresh air flow but also the portion of the recirculated exhaust air needs to be precisely adjusted. For this purpose, both the exhaust gas recirculation valve and the control valve must be operated in a controll...
