Internal combustion engine operating method, involves processing output signals of combustion chamber pressure sensor to heating process, and deriving parameter characterizing injected fuel amount from heating process

摘要

#CMT# #/CMT# The method involves processing output signals (pZyl) of a combustion chamber pressure sensor (7) to a heating process. A parameter characterizing an injected fuel amount is derived from the heating process. Heat amount is transferred with a predetermined crankshaft angle, and is used for characterizing the injected fuel amount. Injection amounts of cylinders of the internal combustion engine are controlled, and combustion noise of the cylinder of an internal combustion engine (1) is controlled. #CMT# : #/CMT# Independent claims are also included for the following: (1) a computer program with a program code for performing a method for operating an internal combustion engine (2) a control device for an internal combustion engine. #CMT#USE : #/CMT# Method for operating an internal combustion engine. #CMT#ADVANTAGE : #/CMT# The parameter characterizing the injected fuel amount is derived from the heating process, thus providing fast adjustment of sensor or actuator errors occurred during the operation of the internal combustion engine, and expanding a region, within which the sensor or actuator errors occur. The method individually controls pre-injection and main injection, thus maintaining the life time of the internal combustion engine within very narrow limits. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block representation of a method for operating an internal combustion engine.'(Drawing includes non-English language text)' pZyl : Output signals 1 : Internal combustion engine 3 : Injector 7 : Combustion chamber pressure sensor 9 : Rotary position sensor.
