    Abstract: A method of reducing tensile stress within a drilled element 100 at an intersection 130 between a primary bore 110 and a secondary bore 120 comprises the following steps. A first face of the drilled element 100 is loaded with a first loading element. A compressive hoop stress is generated where the first face of the drilled element 100 is loaded by the first loading element, and the intersection 130 is sufficiently close to the first face of the drilled element 100 such that the compressive hoop stress counteracts tensile stress in the drilled element 100 at the intersection 130. A suitable drilled element 100 and fluid flow systems, such as a fuel injector, including such a drilled element 100 are also described.

    Abstract: An electrical connector assembly including a first connector having a first casing and a first contact and a second contact, and a second connector having a second casing and a first and a second contact. The first and second connectors are configured to transition between an unassembled condition and an assembled condition to connect the first contacts together and the second contacts. The second connector supports a connector position assurance (CPA) element. In the unassembled condition, the CPA element abuts against a surface borne by one of connectors, thereby preventing movement of the CPA element relative to the second connector between a safety and an active position. In the assembled condition, the CPA element does not abut against the surface and is movable relative to the second connector between the safety and active positions, so as to connect the contact carried by the CPA element with the corresponding contact.

    Abstract: A selective catalytic reduction (SCR) catalyst control system and method for an engine is disclosed. Urea injection to an SCR catalyst is determined based on an SCR catalyst model, which determines a value of stored NH3 in the SCR catalyst based on the NOx engine emission value, the SCR catalyst temperature, the quantity of urea supplied to the SCR catalyst and a pre-determined efficiency of conversion of NOx gases. A target value of stored NH3 and the value of stored NH3 in the SCR catalyst is then used to determine a stored NH3 differential, which is then used to calculate urea injection.

    Abstract: A fuel injector for an internal combustion engine includes an injector body, a first actuator for controlling movement of a first valve needle for injecting a first fuel into a cylinder of the engine, and a second actuator for controlling movement of a second valve needle for injecting a second fuel into the cylinder. Each of the actuators are axially spaced along a longitudinal axis of the injector body and has a respective conductive element for carrying current to the actuator, the injector further includes an electrical connector module which has first and second electrical connectors for connection with an associated one of the conductive elements for the actuators. The electrical connector module is mounted between the first and second actuators along the longitudinal axis of the injector body.

    Abstract: A method of operating an internal combustion engine is proposed, the engine comprising an exhaust system with a DOC and a DPF and, downstream thereof a SCR catalyst. The ECU is configured to allow operation in at least one of a normal mode and a heat-up mode. A predicted temperature evolution of said second exhaust after treatment means is regularly determined based on a thermal model taking into account the thermal inertia of the exhaust system and having as input the current temperatures of the DOC/DPF and SCR. The predicted temperature evolution of SCR is indicative of the temperature that the SCR may reach during a simulated time period in case the operating mode. The engine operating mode is changed depending on the predicted temperature evolution.

    Abstract: A valve assembly suitable for use as an inlet metering valve of a fuel injection system comprises an inlet opening, an outlet aperture, and a valve element arranged to control fluid flow between the inlet opening and the outlet aperture. The valve element is moveable in response to an applied control signal to a closed position and to a fully-open position, and is biased to return to a rest position when the control signal is absent. When the valve element is in the rest position, fluid flow between the inlet opening and the outlet aperture is permitted at a relatively low rate. When the valve element is in the closed position, fluid flow between the inlet opening and the outlet aperture is substantially prevented. When the valve element is in the fully-open position, fluid flow between the inlet opening and the outlet aperture is permitted at a relatively high rate.
