Fuel e.g. petrol, injection controlling method for e.g. petrol engine of automobile, involves simultaneously decreasing fuel injection time during shifted phasing of injection until fuel injection cut-off of injector

摘要

#CMT# #/CMT# The method involves controlling an injector for shifting fuel injection phasing in an intake duct beyond the closing time of an inlet valve. Fuel injection time is simultaneously decreased during the shifted phasing of injection until the fuel injection cut-off of the injector, where the shifting period of the injection phasing until the injection cut-off is parametrable in the number of operating cycles of a non-spark or spark ignition engine. #CMT#USE : #/CMT# Method for controlling injection of fuel e.g. petrol, for a non-spark ignition engine and a spark ignition engine (claimed) e.g. petrol engine, of an automobile. #CMT#ADVANTAGE : #/CMT# The method enables reduction of unburned hydrocarbon quantity during beginning of fuel injection cut off and exothermic catalyst using the simultaneous actions on the injection phasing and on the injection time. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graph representing the variation of injection phasing according to an operating time of a non-spark or spark ignition engine proportional to the number of cycles of the engine.`(Drawing includes non-English language text)` PAO : Open inlet valve injection phasing PAF : Closed inlet valve injection phasing.
