More Information
Summary:The monitoring injection of hydrocarbons in the exhaust pipe of an internal combustion engine is carried out by injecting periodically, at different time interval, a specific quantity of hydrocarbons upstream to the catalytic elimination system, due to pulsed injection of hydrocarbons. The catalytic conversion of nitrogen oxide is carried out using a platinum/aluminum catalyst.
