FUEL INJECTOR ENERGIZATION CONTROL METHOD AND COMMON RAIL FUEL INJECTION CONTROL APPARATUS

Deterioration of a start characteristic of a fuel injector, which is caused by sludge, at a start of an engine is reliably suppressed or prevented. Non-injection energization is performed on fuel injectors 2-1 to 2-n at a start of a vehicle (S102), and a valve closing time at the time is measured (S...

Zusammenfassung:	Deterioration of a start characteristic of a fuel injector, which is caused by sludge, at a start of an engine is reliably suppressed or prevented. Non-injection energization is performed on fuel injectors 2-1 to 2-n at a start of a vehicle (S102), and a valve closing time at the time is measured (S104). If the valve closing time exceeds a specified range (S106), a cause that deteriorates a starting state of an engine 3 is present, and energization control of the fuel injectors 2-1 to 2-n is executed on the basis of a corrected energization condition until an engine speed exceeds a specified speed (S110, S112) . In this way, the deterioration of the start characteristic at the start of the engine is suppressed or prevented.
