摘要
An engine operating method and a direct injection gaseous fuelled system directly injects a gaseous fuel into a combustion chamber during a compression stroke, commands gaseous fuel injection pressure to a target value that is determined as a function of at least one pre-selected engine parameter, measures actual gaseous fuel injection pressure and adjusts fuel injection pulsewidth to correct for differences between the target value and the actual gaseous fuel injection pressure to thereby inject the desired mass quantity of gaseous fuel as determined from an engine map.
