Abstract

In this paper, an analysis of the pollution limits generated due to faults in a spark ignition engineassociated to the low ignition voltage and to the change in the air/fuel ratio, using control charts is presented. For this, the emission data of gases generated in the vehicle is collected in normal operation and failure conditions. Subsequently, control charts are made for the mean and the range of each type of polluting agent. From the limits defined in normal operating conditions of the engine, the sensitivity of these cards for the detection of out-of-control values, obtained from the induction of the aforementioned faults, is tested. The obtained results show that, under normal operating conditions, the upper control limits obtained do not differ significantly from the maximum admissible values established in international environmental regulations, and that the highest values registered of polluting emissions together with the sudden changes on the developed control charts, they are presented for the rich dosage and therefore all failures that generate this type of mixture must be considered as critical due to the impact it generates in the ecosystem.
