FUEL INJECTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE, COMPRISING A HYDROCARBON INJECTOR

摘要

The invention relates to a fuel injection system comprising a hydrocarbon injector (16), wherein the supply pressure of a pre-supply pump (5) is used for the fuel supply of the hydrocarbon injector (16). When the hydrocarbon injector (16) injects fuel into the exhaust gas system of the internal combustion engine, the pressure in the low pressure section of the fuel injection system is temporarily increased.
