AIR FUEL RATIO CONTROL FOR AN INTERNAL COMBUSTION ENGINE THAT CAN BE OPERATED WITH FUELS AT DIFFERENT PROPERTIES

Toyota Jidosha Kabushiki ...

1. A control system for an internal combustion engine which uses fuel having a possibility that a property may change every time being charged, the control system for the internal combustion engine comprising:a controller, comprising at least one processor, configured to:
perform air-fuel ratio feedback control for determining a fuel injection amount so that an air-fuel ratio approaches a target air-fuel ratio, in which a first correction value is determined depending on a difference between a detected air-fuel ratio of an air-fuel mixture com busted in the internal combustion engine and the target air-fuel ratio, and the fuel injection amount is determined using the first correction value and a second correction value; and
when an absolute value of the first correction value in the air-fuel ratio feedback control becomes larger than a predetermined threshold value after fuel is charged, perform fuel property learning control for correcting the second correction value so that the absolute value of the first correction value becomes not more than the predetermined threshold value; and
a storage storing a fuel property learning correction value range as such a range of the second correction value that allows an air-fuel ratio of an air-fuel mixture to be included in an air-fuel ratio range in which combustion can be continued in the internal combustion engine;

SYSTEM AND METHOD FOR ESTIMATING THE QUANTITY OF PARTICULATE ACCUMULATED IN THE PARTICULATE FILTER OF A DIESEL ENGINE

Fiat Group Automobiles S....

1. A diesel engine system for a motor vehicle, comprising:a particulate filter interposed in an exhaust line of an engine, and an electronic control unit controlling fuel injectors which are associated with cylinders of the engine, said electronic control unit being programmed for activating, when an estimated amount of particulate accumulated in said particulate filter exceeds a threshold value, a control mode of the injectors in which a regeneration of the particulate filter is obtained through an increase of a temperature of exhaust gases fed to the particulate filter which is sufficient to burn the particulate within the particulate filter,
wherein the electronic control unit is configured for applying a statistical model, which estimates an amount per time unit of particulate accumulated within the particulate filter, on the basis of operating conditions of the engine and of the vehicle, and
wherein said system comprises a sensor configured to detect an exit temperature of the exhaust gases at an exit from the particulate filter and in that said electronic control unit is configured to correct said estimated amount of the accumulation of particulate after each particulate filter regeneration, on a basis of a comparison between an actual variation of said exit temperature detected by said sensor during regeneration and a reference variation of an exit temperature stored in said electronic control unit and previously detected empirically during a regeneration with said particulate filter being empty such that the particulate filter is without particulate accumulated therewithin, wherein said correction of said estimated amount of the accumulation of particulate after each particulate filter regeneration is based on a direct comparison of said exit temperature detected and said exit temperature stored.
