    Abstract: A connector arrangement for a fluid system, comprising a component (40), more particularly being an automotive fuel injector, that defines a first fluid passage (64) having a connector (68), a pipe (68) that is engageable with the connector (68) of the first fluid passage (64), preferably to form a high pressure seal, and connecting means (74) arranged to connect the pipe (68) to the connector (68) of the first fluid passage (64). A chamber (88) is defined between the connecting means (74) and the component (40), such chamber serving to collect leaked fluid from the first fluid passage (64). The first component is provided with a second fluid passage (100) having a first end in communication with the chamber (88) and a second end in communication with a low pressure drain such that leaked fuel is provided with a drain path. The invention is also applicable to other components which are supplied with fluid from a pipe, or which supply fluid to a pipe, and for which potential leakages must be managed appropriately.

    Abstract: An inlet valve arrangement for a pump head of a fuel pump for use in a common rail fuel injection system comprises an inlet valve member (10) moveable between open and closed positions to control the flow from a source of low-pressure fuel to a pumping chamber (6) of the fuel pump. The inlet valve member (10) is arranged to open in response to the pressure difference between the fluid pressure of fuel on an inlet side of the inlet valve member (10) and the fluid pressure in the pumping chamber (6) exceeding a threshold value. The inlet valve arrangement (9) comprises means for selectively applying a closing force on the inlet valve member (10) to bias it toward the closed position, such that, in use, the application of the closing force by said means acts to increase the threshold value of the pressure difference at which the inlet valve member (10) opens.

    Abstract: A method of monitoring functional capability of a soot sensor (10) that is responsive to deposition of soot (18) from an exhaust gas stream on a sensor surface (14) comprises acquiring a measurement signal (61) of the soot sensor and running a plausibility check, in which it is ascertained whether the measurement signal agrees with an expected finding (66). According to the invention it is detected whether conditions are present, on which liquid, e.g. water, from the exhaust gas stream condensates on the sensor surface. Additionally or alternatively, such conditions are produced. The plausibility check then includes ascertaining whether the measurement signal reflects (60) the condensation of liquid. The detection of presence of conditions for condensation comprises a measurement or an estimation of temperature on the sensor surface (14).
