| 摘要 |
An injector apparatus for an internal combustion engine and suitable for injecting two different fuels, namely a "pilot injection" liquid fuel and a "main injection" liquid or gaseous fuel comprising a low-pressure pump (1B) for pilot injection fuel feed, a high-pressure pump (1A) of the injection pump type, two fuel injectors, and a metering pump (30) selectively connecting the low-pressure pump, the high-pressure pump, and the two fuel injectors. The metering pump (30) includes a transfer piston (2) and two abutments (3, 4) which are independently adjustable so as to vary the relative importance of pilot injection and of main injection and also vary the extent to which the two injection stages overlap. |
