Exhaust gas recirculation valve opening control method for internal combustion engine, involves opening recirculation valve according to value representative of nitrogen oxide emission rate, which is measured in exhaust circuit of engine
Exhaust gas recirculation valve opening control method for internal combustion engine, involves opening recirculation valve according to value representative of nitrogen oxide emission rate, which is measured in exhaust circuit of engine
The method involves adjusting an opening of an exhaust gas recirculation valve (10) according to a value representative of nitrogen oxide emission rate, which is measured in an exhaust circuit (4) of an internal combustion engine (1). The exhaust gas recirculation valve is inserted in a bypass (6) extended between the exhaust circuit and intake circuit (2) of the internal combustion engine. An independent claim is also included for a device for implementing an exhaust gas recirculation valve opening control method.
