Diagnosis and the engine management system which have the device and method, and that device which calculate the quantity of NOx which is discharged from the Diesel engine of the motor transport

摘要

This invention the common rail fuel supply expedient for the cylinder (12) the Diesel engine of the motor transport which it possesses (10) from being the device which calculates the quantity of NOx which is discharged, the expedient which acquires at least the pressure of one cylinder of the engine (32) with, the expedient which calculates the mass amount ratio of the oxygen of the mixture which was sucked to inside the cylinder (50) with regards the device of the type which it has. The device has the expedient which calculates the quantity of NOx which is discharged the expedient which calculates the temperature of the flame surface of mixture combustion (58 and 68) with, the expedient which calculates the mass of the fuel which burnt inside the cylinder (52) with, mass amount ratio of pressure and the mixed air oxygen which are recorded, as a temperature of the flame surface, and a function of mass of the fuel which burnt, by the combustion of the mixture inside the cylinder (70) with.
