Motor vehicle`s engine controlling method, involves determining loss and failure of combustion in combustion chamber of engine by comparing running average value of preset variable of engine with preset threshold value

摘要

#CMT# #/CMT# The method involves determining loss and failure of combustion e.g. diesel combustion, in a combustion chamber of an engine by comparing a running average value of a predetermined variable of the engine with a predetermined threshold value. The running average value of the variable is modified when the failure of combustion is detected, where the variable depends on release of energy of a gas in the combustion chamber. #CMT#USE : #/CMT# Used for controlling an engine (claimed) of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The running average value of the predetermined variable of the engine is compared with the predetermined threshold value, thus reducing the noise of measurement of the variable, and reducing the influence of the failure of combustion on determination of the combustion loss, and hence rapidly and easily detecting the loss and failure of combustion in the combustion engine of the engine in a reliable manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart of a method for controlling an engine of a motor vehicle.`(Drawing includes non-English language text)`.
