Engine control system based upon a quick detection of exhaust gases

摘要

An arrangement for carrying out a motor vehicle engine control on the basis of a rapid exhaust gas sensor system, in which a combination of a conventional lambda probe (1) with an exhaust gas sensor (2) which detects changes in the O2 content of the exhaust gas and, at the same time, is insensitive to temperature fluctuations and long-term drifts is provided. The exhaust gas sensor (2) is arranged in the area (2a) of the outlet section (3) of the respective internal combustion engine (4) near to the cylinder at a location at which the individual exhaust gas bursts (5) of the cylinders of the internal combustion engine (4) are not yet completely mixed with one another, the lambda probe (1) being arranged at the conventionally predetermined location (1a) at a greater distance from the outlet valves of the cylinders (51...54), where the lambda value averaged over all the exhaust gas bursts (5) is measured and provided as an engine control variable.
