发明名称 Fuel injection system for internal combustion engine comprising two fuel injectors
摘要 A fuel injector for an internal combustion engine (2) including an in-cylinder fuel injection valve (4a,6a,8a,10a,12a,14a) and an intake port fuel injection valve (4b,6b,8b,10b,12b,14b). An ECU (56) controls an electromagnetic valve (42b) to keep a fuel inlet (42a) of a high pressure pump (26) 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 (34) reciprocates in the high pressure pump (26), fuel does not flow between the high pressure pump (26) and a low pressure fuel path (42). Thus, pressure pulsation that would be caused by the operation of the high pressure pump (26) does not occur in low pressure fuel. <IMAGE>
