Operation of a diesel motor, for low exhaust emissions, sets the air intake mass flow according to the oxygen concentration in the exhaust gas before cleaning

摘要

The system is for the operation of a diesel motor, where the air intake (1) and exhaust outflow (4) at the cylinders are connected to their combustion zones (9) through the valves (12,13). A nominal oxygen concentration value is detected in the exhaust gas, before gas cleaning, according to at least one motor working value. A nominal fresh air mass flow value is detected according to the exhaust oxygen concentration for the motor running to be set according to it.
