PRESSURE REGULATION METHOD FOR A FUEL INJECTION SYSTEM

摘要

Disclosed is a method of controlling the gas pressure in a dual fluid injection system wherein the gas is used to deliver a metered quantity of fuel to a combustion chamber (60) of an internal combustion engine (20). On detection of an abnormal fuel supply condition, gas pressure in the fuel injection system is regulated to a level less than the fuel pressure deliverable by a fuel supply system of the engine (20) under the abnormal fuel supply condition. In this way, fuel may be delivered as required to the dual fluid fuel injection system.
