AI Technical Summary

Technical Problem

Existing lambda control systems for internal combustion engines do not effectively adapt to geographical and operational conditions, leading to inefficient emissions control and potential engine damage.

Method used

A device and method for lambda control that adjusts lambda setpoints based on geographical location, using GPS and radio signals to switch between different lambda settings, including a first and second setpoint, with the second setpoint being lower than the first, and allowing for operation with a rich mixture in specific areas like race tracks or during payment instructions.

Benefits of technology

Enhances emissions control by optimizing lambda settings for different geographical areas and operational conditions, reducing emissions and protecting the engine from damage.

Abstract

Method for lambda control of an internal combustion engine (101), wherein the lambda control is performed with a first lambda setpoint (202) when it is determined (201) that the internal combustion engine (101) is operated within a specified geographical area, and wherein the lambda control is performed with a second lambda setpoint smaller than the first lambda setpoint (203) when it is determined (201) that the internal combustion engine (101) is operated within the specified geographical area and a radio signal is received which includes an instruction for paid activation of the internal combustion engine (101) to operate with the second lambda setpoint.
