Improved process to reduce the formation of deposits derived components in the Fuel Injector fuel supply system in an internal combustion engine and the systemWith this improved used

摘要

The present Invention relates to improved process to reduce the formation of deposits derived components in the Fuel Injector fuel supply system in an EngineInternal combustionIt comprises the steps of: providing a source of fuel for fuel under pressure to media type port fuel injectors close Tolerance by means of a linePressurized Fuel connected to the fuel Source; having a fuel pump to maintain the pressurized Fuel Line Pressure supraatmosfu00e9rica predeterminadDuring the operation of the Internal Combustion Engine; connecting a fuel return Line, through which the fuel which enters the Injector.Return from the area of the injectors to the fuel sourceThe Fuel return Line operates at a Lower operating pressure in the pressurized Fuel Line during the operation of the internal combustion Machine; maintaining and controllingPressurized Fuel Line Pressure through regulatory means of pressure placed on the system.In combination with these stages include the Improvement comprises: means for despresurizadores depressurize or decompress automatically pressurized Fuel line in response to the outputException of the Internal Combustion Engine, to a pressure less than approximately 10 kPa, which reduces the formation of Harmful Deposits on Injector components.
