Exhaust gas inlet flow control valve opening or closing control method for e.g. diesel engine, involves controlling valve based on acquired pressure difference between filling and swirl plenum chambers and acquired characteristics value

摘要

#CMT# #/CMT# The method involves acquiring difference of pressure between filling and swirl plenum chambers (25, 26) of an air distributor (24) in an internal combustion engine (1) using pressure transducers (101, 102), and acquiring a value of determined characteristics such as speed value or load value, relative to an operation point of the combustion engine. An exhaust gas inlet flow control valve (27) is controlled based on the acquired pressure difference and the acquired characteristics value. #CMT# : #/CMT# An independent claim is also included for an internal combustion engine including two cylinders and an air distributor. #CMT#USE : #/CMT# Method for controlling opening or closing of an exhaust gas inlet flow control valve in a plenum chamber of an air distributor of an internal combustion engine (claimed) e.g. diesel engine. #CMT#ADVANTAGE : #/CMT# The method controls opening or closing of the gas inlet flow control valve within the plenum chamber of the air distributor in reliable manner without depending on the geometry differences between the engines while avoiding swirl movements affecting proper functioning of the engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an internal combustion engine. 1 : Internal combustion engine 24 : Air distributor 25 : Filling plenum chamber 26 : Swirl plenum chamber 27 : Exhaust gas inlet flow control valve 101, 102 : Pressure transducers.
