Fuel injector for internal combustion engine |
摘要 |
A fuel injector for an internal combustion engine including an in-cylinder fuel injection valve and an intake port fuel injection valve. An ECU controls an electromagnetic valve to keep a fuel inlet of a high pressure pump closed during an intake port injection mode during which fuel is injected only from an intake port fuel injection valve. As a result, even if the plunger reciprocates in the high pressure pump, fuel does not flow between the high pressure pump and a low pressure fuel path. Thus, pressure pulsation that would be caused by the operation of the high pressure pump does not occur in low pressure fuel.
