Rail pressure regulator, which is installed in high-pressure pump, controls rail pressure as regulating fuel quantity supplied to the common rail. ECM performs duty control of rail pressure regulator in order to keep rail pressure at target rail pressure according to current engine loading condition.
As rail pressure regulator duty rises, more fuel flows into common rail so, rail pressure increases.
When rail pressure regulator operation stops due to the power supply cut off to rail pressure regulator, the maximum fuel quantity flows to common rail as passage inside regulator fully opened.
