The catalyst is used to control and reduce the harmful gases expelled by the internal combustion engine. It is used both in gasoline engines or Otto cycle and more recently in the diesel engine. The performance of this element is electronically controlled by the oxygen sensors (lambda) upstream and downstream of the catalyst, when it is in bad condition it is detected by the engine module turning on the Check-Engine light and in some cases going into mode. limiting the correct operation of the engine. Unfortunately, the loss of efficiency of the engine, the poor quality of our fuel or the life time of the spare part produce stagnation and obstruction in the exhaust circuit causing lack of power, increased fuel and a high replacement value of this. system. Our rescheduling services can help reverse these problems
