摘要

A novel strategy for closed-loop controlling the stoichiometric combustion of gasoline engines is presented. In contrast to common strategies which use the signal two lambda probes up- and downstream of a three way catalyst to control the engine, here the oxygen loading degree of a threeway catalyst is directly and in-operando determined by a radio frequency-based method and used as the process variable. Initial tests at a high dynamic laboratory test bench show that such a controlling strategy may lead to much lower emissions. Hence, there is a chance to replace lambda probes.
