Abstract:
Connector assembly for electrical power supply or transmission in vehicles, comprising first and a second connector devices to be mated according to a mating axis. The first connector device comprises at least one spring device terminated by at least one electrically conductive head, movable in a spring load direction. The second connector device comprises at least one interlock terminal including an electrical conductor and an insulation cap arranged in such a way that, during the mating sequence, the at least one head touches first the insulation cap on one or several insulating areas and then contacts the electrical conductor on one or several conducting areas. Each of the one or several insulating areas is offset laterally with respect to each of the one or several conducting areas, according to a lateral direction perpendicular to the mating axis and to the spring load direction.
Abstract:
A connecting bus includes an electrically conductive bar comprising two electrical connector assemblies. At least one of the two electrical connector assemblies includes a female connector having at least one electrically conductive spring tongue. For each of the electrical connection assemblies included in the connecting bus, the electrically conductive bar includes a corresponding non-isolated zone surrounding the electrical connection assembly. The electrically conductive bar further includes an outside electrically insulating layer surrounding the whole electrically conductive bar apart from the non-isolated zone.
Abstract:
An electrical male terminal formed from a metal plate comprising a mating portion having contact surfaces adapted to electrically contact a female terminal. The mating portion comprises a first and second seamless strip electrically contacting the first and second female contact surfaces. The male terminal has a seam comprising a mating portion seam, within the mating portion, which is parallel to the longitudinal axis, and located on one of the side portions which are perpendicular to the contact surfaces of the mating portion.
Abstract:
A compression-ignition engine (10) comprises an exhaust system (16) with an exhaust gas after-treatment assembly, the after-treatment assembly comprising a three-way catalyst device (30) and an SCR device (34), the three-way catalyst device being arranged upstream the SCR device in close-coupled position with respect to the engine. An engine control unit (47) is provided for controlling operation of the engine. The engine control unit is configured to monitor the temperature of the SCR device and to control the engine to change over from an operation with a lean air/fuel mixture to an operation with a stoichiometric or a rich air/fuel mixture in response to the temperature of the SCR device dropping below a temperature threshold.
Abstract:
Electrical connector including at least one electrical power contact having a cross-section larger than 8 mm2 and adapted to mate with a complementary connector. The at least one power contact includes a front end adapted to be electrically connected with a first complementary contact of said complementary connector. The at least one electrical power contact includes a back pin having a back pin extremity located at the opposite end of the power contact with respect to the front end and adapted to be electrically connected with a second complementary contact of a second connector.
Abstract:
An injection nozzle comprising a nozzle body provided with a bore within which a valve needle is moveable, the valve needle being engageable with a valve seating to control fuel delivery through a set of nozzle outlets, said nozzle outlets including respective entry openings defined in a wall of a sac volume of the nozzle body, wherein the valve needle includes a first valve region, a second valve region and a seat region defined by a transition between the first and second valve regions which seats against the valve seating when the nozzle is in a non-injecting state. The valve needle comprises a third valve region adjacent the second valve region, the third valve region having an outer surface defining a curved profile, the end of the outer surface terminating substantially in alignment with the entry openings when the valve needle is engaged with the valve seating.
Abstract:
A method of providing electronic trim data for a fuel injection device to an engine system, the method comprising: reading an identifier associated with the fuel injection device; accessing a database containing trim data associated with the identifier; downloading the trim data for the fuel injection device; uploading the downloaded trim data to the engine system for use in controlling fuel injection device operation.
Abstract:
The present invention relates to a contact terminal for the reception of contact pins. The terminal includes a pin reception member having a box-shape made from a single piece of sheet metal, wherein two opposite walls include each at least one cut-out contact tongue being inwardly bent into the interior of the box-shape. Two other opposite walls include each a contact front portion which is inwardly bent such that the respective wall has essentially a hook-shaped cross-section to clampingly receive a contact pin.
Abstract:
The present invention relates to an electrical connector system. The electrical connector system includes a first connector to be mated to a corresponding counter connector and it is further adapted to be connected to a signal circuit for activating an electrical power source upon switching. As a safety feature, the connector system further includes a connector position assurance (CPA) member assigned to the first connector, which is movable, whereby an end position is not reachable if the first connector is incorrectly mated to the counter connector. The CPA member is adapted to interact with the signal circuit if placed in said end position so that it activates of the electrical power source.
Abstract:
A method of determining whether a cylinder in an engine system comprising a plurality of cylinders is ready for injection/ignition, the method comprising: monitoring the in-cylinder pressure of each of the plurality of cylinders within the engine system; determining a pressure related parameter for each cylinder within the engine system; wherein, in the event that the pressure related parameter in a given cylinder exceeds a first threshold, the method further comprises performing a diagnostic test in order to determine whether the given cylinder is ready for injection/ignition.
